Section 1 – Introduction About
This Manual
This manual provides information to set up, operate, and interface Dukane’s
model 220 20kHz Press/Thruster. The manual consists of sections that
describe in detail press specifications and functions, installation and testing procedures, and maintenance and troubleshooting steps. Each section describes all of the press functions that are applicable to a standard
press/thruster.
Note that the manual covers the Model 220 & Model 340 Press/Thruster
only. Refer to the user manual for the Dynamic Process Controller™ (DPC)
for additional information regarding safety, connections, and programming
for the entire assembly system.
Safety
Safety Recommendations
Your safety is important!
This symbol warns you of any hazard or unsafe practice that could result in personal injury or equipment damage. Carefully read and observe all cautions and
warnings that appear in this manual.
To operate the equipment in a safe and efficient manner and avoid possible
injury, please observe the following safety measures:
•
Do not operate the system before it is properly installed.
•
Any unauthorized modifications to the control circuitry or other parts
of the system could cause damage to the equipment and/or injury to
the operator.
•
Do not operate this equipment without a grounded connection.
•
Accessories may be required for compliance with applicable OSHA
regulations for machine guarding and noise exposure.
Dukane Part No. 403–556–03
Page Model 220/340 Press User's Manual
•
When ultrasonic plastic assembly equipment is used with automatic
material handling equipment as an automated system, a SYSTEM
ABORT switch should be located at each operator station.
•
Use of a foot switch in place of dual palm buttons violates OSHA
regulations.
•
DO NOT touch the horn tip when the system is operating. Touching a
horn tip that is vibrating at ultrasonic frequencies can result in serious
injury.
•
The operator’s head should be kept at least six (6) inches away from
the horn and transducer during the system operation.
•
At times, parts being ultrasonically joined may vibrate at frequencies
that are audible to the human ear. Ear protectors may be worn to reduce annoyance or discomfort from the resulting high-pitched sound.
Ultrasound baffles, sound enclosures, or acoustical absorbing materials
may also be located in the vicinity of the system to reduce the level of
high-frequency sounds.
•
A system using pre-trigger must be adjusted so that the ultrasound will
not fire when the horn is any further than 1/4 inch away from the part
to ensure safe operation. This is because the pre-trigger switch option
starts the horn vibrating before it contacts the part.
•
Do not wear loose clothing or jewelry as they can become caught in
moving parts.
•
Use eye protection. Wear ANSI approved safety impact goggles.
•
Stay alert and watch what you are doing at all times. Use common sense.
Do not operate the press when you are tired or distracted from the job
at hand.
•
Do not operate the press if under the influence of alcohol or drugs.
Read the warning labels on prescriptions to determine if your judgement or reflexes are impaired while taking drugs. If there is any doubt,
do not operate the machine.
Other safety recommendations are included in the manual where they
apply.
Page Dukane Part No. 403–556–03
Section 1 – Introduction Special Health Notice – Plastics
Certain plastic materials, when being processed, may emit fumes
and/or gases that may be hazardous to the operator’s health. Proper
ventilation of the work station should be provided where such
materials are processed. Inquiries should be made to the U.S. Department of Labor concerning OSHA regulations for a particular
plastic prior to processing with Dukane ultrasonic equipment.
CAUTION
If there is any question about the
grounding of your
receptacle, have it
checked by a qualified electrician. Do
not cut off the power cord
grounding prong, or alter the
plug in any way. If an extension
cord is needed, use a three-wire
cord that is in good condition.
The cord should have an adequate power rating to do the
job safely. It must be plugged
into a grounded receptacle. Do
not use a two-wire extension
cord with this product.

Electrical Safety Grounding
The Dynamic Process Controller (DPC) provides the operating
power and power returns: Refer to the DPC manual for full information regarding electrical grounding and safety. In addition
to the safety considerations, proper grounding is essential for the
effective suppression of RFI (Radio Frequency Interference).
Every DPC contains a RFI filter which blocks noise on the AC
power line from entering the DPC control circuitry. This filter also
prevents ultrasonic RFI from being fed back into the AC power
line. If you experience problems with RFI from the press, run an
additional grounding wire from the press base grounding stud (see
Figure 2-6) to the nearest grounded metal pipe or equivalent earth
ground by means of a ground clamp. Use at least 14 AWG wire
for the connection to the press base.

CAUTION
To ensure safe and trouble–free operation, ground
the DPC chassis and the
press/thruster.
Use a STAR configuration (illustrated below).
Do not DAISY CHAIN the
grounds.

Section 2 – Installation Installing the Press System
The press system consists of a thruster, ergonomic base and support package. It is assembled at the factory for shipment.
Unpacking
The press system is secured to a wooden pallet and covered with a cardboard
carton. The press sits on the pallet and is supported inside the carton by
styrofoam blocks.
1.
Before unpacking, it is suggested that the press be moved close to the
location where it is to be installed.
2.
Remove the straps from the carton.
3.
Open the carton and remove the packing material and the cables.
4. Cut the tape located at the bottom corners and unfold the flaps.
5.
Remove the carton, as shown in Figure 2-1, leaving the press on the
shipping base.
6.
Inspect the assembly for any possible damage before placing it in
position.
Placement
Figure 2-1Unpacking Press System
CAUTION
Manually lifting the
press system could
result in injury
Dukane Part No. 403–556–03
DO NOT LIFT the Press
manually. Lifting and/
or moving the Press
manually could result in
personal injury. Use mechanical means to move
and place the Press.
Page Model 220/340 Press User's Manual
The placement of the press system should be by mechanical means.
To place the press on the work area, use a pallet lift platform or equivalent. Raise the assembly until the bottom edge of the base is even with
the top of the work area as shown in Figure 2-2. Then, carefully slide
the press system on to the work area.
Installing the Press System
Without Machine Base
In this configuration, secure the flange to a rigid, level stationary structure. We recommend socket-head cap screws M12 -1.75 with a minimum
length of 40 mm for securing the flange to the supporting structure. We
recommend a minimum of 1 inch (25.4 mm) full thread engagement
of the cap screws into the supporting structure. Depending upon the
thickness and material of the supporting structure, longer screws and/or
additional hardware may be required.
A full scale template is provided for locating and drilling holes in the
supporting structure. The template is on the last page of this section.
Press Height Adjustment
The height of the thruster on the column is adjustable. Adjustment is
made by first turning the two handles located on the left rear side of
the press.
•
To loosen the grip on the column, turn the handles counterclockwise,
as shown in Figure 2-3a. The counterbalance spring on the column
supports the weight of the thruster while the handles are loose. If a
thruster is not installed, the unloaded column may rise up unexpectedly, so be careful to avoid injury.
•
Adjust the column to the desired height.
•
Turn the handles clockwise, as shown in Figure 2-3b, until tight.
•
To rotate the handles out of the way without loosening or tightening,
pull the handles outward, rotate and release, as shown in Figure 2-4.

Section 2 – Installation Installing the Thruster
Secure the thruster to a rigid stationary structure by placing the back of
the thruster onto the support frame. Align the bolt holes in the thruster
with the bolt slots in the support frame. Insert the two mounting bolts
(3/8-16 x 1-1/4 inch hexhead or equivalent), with flat washers, as shown
in Figure 2-5. Align the thruster with the work surface in both the
horizontal and vertical planes to assure parallelism. Tighten the bolts.
Mounting
Holes
Washers
When mounted to a Dukane column as in the press configuration,
the height of the thruster is adjustable on the column. If the height
of the thruster is not adjustable in your mounting arrangement, you
must consider the distance from the horn tip to the work surface when
determining the position of the thruster.
Mounting
Bolts *
The distance between the tip of the retracted horn and the parts in
the fixture must be less than the maximum travelling distance (stroke)
of the thruster slide assembly. If greater, the horn will be unable to
contact the parts during operation. The maximum stroke distance is
177.8 mm (7 inches).
A shorter distance between the retracted horn tip and the parts in the
fixture means a shorter travelling distance (stroke) during operation
which results in two advantages:
•
A more stable thruster when applying pressure to the parts
•
A shorter duty cycle for a faster production rate
Rigid
Mounting
*
Distance from
horn to work
surface should be
less than 7 inches.

this cable.
Shut Off Valve
Operational control (J7) - Connects the press functions to the Press
Port (J201), located in the DPC. Through this cable the DPC provides controls for triggering of the weld, operation of the thruster’s
pneumatic system, and 24 VDC operating voltage. The press driver
card in the DPC also provides monitoring for these functions.
•
Air in - This is a threaded receptacle for a compressed air supply
that provides the thruster with the required pressure of 10-100 psi
(1-7 atmospheres) to operate the pneumatic system.
This connector is attached to an air filter on the press. The input
to the filter comes from the air shut-off valve, located on the back,
near the bottom of the press.
•
J1
Top of Stroke (J40) - This receptacle is factory wired to a switch in
the press/thruster that opens when the press/thruster slide assembly
begins extending and closes when the slide assembly returns to the
fully retracted (i.e. top-of-stroke) position. This contact closure is
typically used in automated systems to indicate to the controlling
mechanism when the slide assembly is fully retracted. A Dukane
cable (model number 438-528) mates with this receptacle to allow
access to the switch contacts.
Note: Under normal usage, it is recommended that the voltage applied to the contacts does not exceed 24 VDC @ 2 amps.

The press system requires three cables for proper operation. These cables
are part of the cable package that is shipped with the press. A customerprovided air hose ( 5/16 inch dia.) is also required.
Connect the following lines and cables to the press system:
•
Connect the ultrasound coaxial cable to J1 on the thruster.
DO NOT run the generator unless this cable is connected and the
transducer is installed in the thruster — Otherwise, an overload condition could occur, with possible damage to the generator.
•
Connect the operational control cable to J7 on the thruster.
•
Connect clean, dry air from an air source to the fitting located at the
lower portion of the support package.
Figure 2-6 shows the locations of the connections.
•
Encoder cable (optional) - If the press is equipped with an encoder,
the cable will already be wired in.
•
Connect 9-pin ergonomic base cable to J35 on the back of the base
CAUTION
The compressed air for
the thruster
must be clean,
dry and oil free. Any
particulate, oil contamination or moisture can
coat or clog the valves,
sensors and cylinder
walls. This can result
in premature failure of
the regulator, pressure
transducer, air cylinder or other componets of the pneumatic
system.

the hydraulic speed damper is engaged. The SLOW SPEED Control
knob adjusts to a point along the 7 inch (177.8 mm) of total available
downstroke distance that the hydraulic Speed Control engages. Refer to
Section 4: Press Options, for detailed information on the Hydraulic Slow
Speed Control.
Hydraulic Slow Speed
Adjustment
The Hydraulic slow speed adjustment is an integral part of the optional
hydraulic slow speed control. It sets the amount of velocity damping of
the hydraulic unit. For detailed information on this adjustment, refer to
Section 4: Press Options.
Mechanical Stop Adjustment
The function of the mechanical stop is to halt the down stroke at a
predetermined point. It is used in two ways:
•
To stop the down stroke at a particular depth of travel relative to
the fixture/anvil
•
To prevent the horn from contacting the fixture when there is no
part present. This prevents possible damage to the horn and/or
fixture. Never allow the horn to contact the fixture while ultrasonic
power is applied to the horn. Metal–to–metal contact can void the
horn and/or tooling warranty.

CAUTION
Do not allow
the horn to
contact the
fixture while
ultrasonic
power is applied to the
horn.
Metal–to–metal contact
can void the horn and/or
tooling warranty.
Pressure 1 Regulator
Pressure 1 regulator is used to set the amount of air pressure applied to
the air cylinder during the press down stroke and weld cycle.

Pressure 2 Regulator
In applications where welding with dual pressure is required, this pressure
regulator would be set to provide a higher pressure during a portion of the
weld cycle. This pressure is also maintained during the hold time.
Note: The actual amount of force applied to the part
depends on the following four factors:
• The setting of the regulator(s)
• The area of the air cylinder
• The mass of the horn used
• The surface area of the horn
Regulator Select Switch (Optional)
The Regulator Select switch is used to select Pressure 1 regulator (Weld
Pressure) or Pressure 2 regulator (Hold Pressure) to set the required pressure on each regulator and for monitoring the pressure gauge.
Pre-Trigger Control (Optional)
The pre-trigger control turns the ultrasound on at a preset point in the
thruster downstroke. This control is normally used in staking and inserting
applications. This control should be set for a distance of approximately
6.25 mm (.25 inch) above the part.
Trigger Control
Setting the trigger control determines the amount of pre-load on the part
before turning on the ultrasonics.
End-of-Weld Control (Optional)
This adjustment is set at the point in the stroke of horn travel (absolute
distance) where the ultrasound turns off.

Electronic Pressure Regulator
Refer to Figure 3-2 for the location of the controls.
The EPR (Electronic Pressure Regulator) option deletes the Pressure 1 and
Pressure 2 Regulators and the Regulator Select Switch found on the manual
press, and replaces them with the following:
•
Electronic Pressure Regulator (EPR) that controls the pneumatic pressure on command from the DPC IV.
•
A pressure transducer that functions as the pressure gauge in that it
converts pneumatic pressure into an electrical signal for the DPC IV
to use for feedback control.
and optionally–
•
A load cell that measures applied force. A force transducer converts
the mechanical force applied to the parts into an electrical signal. This
allows the DPC IV to trigger by force.
Note that this option is only functional when used with a DPC IV or
DPC IV Plus. Refer to Section 4: Press Options, for detailed information.

Hydraulic Speed Control
SLOW SPEED Control and
Indicator Flags
CM
The thruster has a knob labelled “SLOW SPEED” near the bottom of
the front panel and an indicator flag in the same slot with the STROKE
POSITION indicator flag. Refer to Figure 4-1.
The knob and the indicator flag are part of the optional Hydraulic Speed
Control Kit.
The purpose of the hydraulic speed control is to match the downstroke
speed to the material melt flow. This will produce the strongest joint. The
Slow Speed Setting knob adjusts the point along the 7 inch (177.8 mm)
downstroke distance at which the hydraulic speed control will engage. It
should be set to engage just before the horn contacts the part. The maximum distance over which this kit can control the downstroke speed is 1
inch (25.4 mm).
The top edge of the indicator flag, when referenced to the yellow scale
beside the flag slot, shows where the 1 inch (25.4 mm) of slow speed is
set to begin.

Figure 4-1Example of Slow Speed Setting
The kit contains a sealed hydraulic cylinder with an external plunger. The
cylinder is mounted to the stationary part of the thruster.
The kit also has a contact block that is mounted to the slide assembly of the
thruster. When the slide assembly descends, the contact block descends until it
engages the plunger of the stationary hydraulic cylinder and pushes the plunger
down into the cylinder. The design of the cylinder resists the downward motion of the plunger by metering the pure silicone fluid through an adjustable
internal flow aperture, resulting in a constant speed of the slide assembly.

Section 4 – Press Options
Threaded
Rod
Contact
Block
The hydraulic cylinder is mounted in a clamping block. The block is
threaded onto a long rod.
Turning the SLOW SPEED knob rotates the rod.
Plunger
This in turn causes the clamping block to ride up or down on the rod,
moving the hydraulic cylinder closer to or further from the contact block
at rest.
This distance determines how far the contact block, and therefore the
slide assembly, must travel before the block contacts the plunger of the
hydraulic cylinder.

Hydraulic Speed Control
Adjustment
Rotating this shaft adjusts the internal metering aperture which regulates the flow of the silicone fluid. There are two ways to adjust the
hydraulic speed control setting. First make sure that the slide assembly
is fully retracted (up position). This will uncover the hydraulic damper
and shaft.
•
Insert the end of a small screwdriver or similar tool into the hole
(Figure 4-3) in the adjustment shaft of the hydraulic cylinder,
OR,
•
Locate the slot on the bottom of the cylinder (Figure 4-4). Insert
a screwdriver in the slot and adjust the setting.
Just above the shaft is a scale with 30 divisions. On the adjustment is a vertical groove that indicates where along the scale the speed is set. Zero (0)
is the fastest setting and thirty (30) is the slowest.

Section 4 – Press Options
4. Connect the cable to the DPC connector J-401 (Thruster Stroke
Encoder).
5. Replace the rear panel on the press.
6. Gently slide the encoder head down until the mounting screw holes
in the press support base appear in the head’s mounting slots.
7. Center the screw holes in the mounting slots. Secure the encoder head
with the two pan-screws but do not tighten them yet.
Alignment
The purpose of this alignment is to set the internal reference mark for
the encoder. This reference mark resets the distance register in the DPC
after each thruster cycle and ensures repeatable distance measurements
from cycle to cycle.
Encoder Scale
1. Check the position of the encoder scale’s mounting hole slots using
the 6" ruler. Measure the distance from the center of the screw to
the edge of the slot in both directions. When the screws are centered
horizontally, carefully tighten the screws.
2. Measure a vertical distance of 1.375 inches (34.92 mm) up from the
bottom edge of the encoder scale, as shown in Figure 4-6.

6. Perform the following procedure to test the encoder for the proper
setting:
a. Run one weld cycle. If the encoder position reads negative
(-.xxx), then the encoder is above the “0” reference point
used for measuring distance by the DPC. This is the correct
setting. Secure the two screws. Proceed to Step 7.
xxx = approximately -.125 inch to .-250 inch.
b. If the encoder position reads positive (+.xxx) after running
one cycle, loosen the two encoder head screws and slide the
head down until the reading goes negative (-.xxx). Secure the
two screws. Repeat Step 6a.
7. Set the gap between the encoder scale and head, using the feeler
gauge .039 inch (1 mm) blade.
8. Measure the gap at the top and bottom of the stroke. Allowable
tolerance, as specified by the encoder manufacturer, is ±.005. This
is a range of from .034 to .044 inches (.864 to 1.12 mm).
9. Tighten all the screws and check the measurements again.
10. Replace the press/thruster right side panel.

Dukane Part No. 403–556–03
Section 4 – Press Options
Electronic Press Controls
The electronic press controls consist of the following three
components:
Electronic Pressure Regulator
The electronic pressure regulator, (I/P transducer) is an electro-pneumatic replacement for the manually adjusted air regulator on the press.
The I/P transducer converts the electrical signal current (I) into air
pressure (P). The Electronic Regulator converts the electrical signal from
the DPC into the programmed air pressure.
The pressure value settings, “Pressure 1” (P1) and “Pressure 2” (P2), are
stored in the Process Setup under Pressure in the DPC. P1 and P2 are
set in pounds per square inch (PSI), or BARS.
To monitor Pressure 1 and Pressure 2 values, use the Check Pressure
parameter, contained in the Operate Setup under View Parameters (on
the DPC).
The DPC uses a pressure transducer to measure the I/P output pressures.
The I/P transducer installed in this thruster/press does not require onsite calibration. The unit is equipped with self- correcting, closed-loop
circuitry.
Pressure Transducer
The pressure transducer (P/I transducer) performs the same function
as the air gauge on the press. The P/I transducer converts air pressure
(P) to an electrical signal current (I). It then sends the signal to the DPC.
The DPC displays this signal as pressure.
Two sets of upper and lower limits can be monitored with the pressure
transducer:
One set is used to monitor the air pressure before a cycle starts.
Using the bad parts limits, the unit will not begin a cycle if the air
pressure is outside the pressure window that has been set.
Dukane Part No. 403–556–03
Page 37
Model 220/340 Press User's Manual
This set of limits is used to ensure that air pressure from the
input line has not dropped below the required pressure for an
acceptable weld force.
The other set of limits is used to monitor the air pressure when
the ultrasound is turned on.
This feature can be used as an indicator when checking for a trigger
or load cell malfunction.
A more precise way to monitor trigger force is to use a load cell.
The pressure transducer does not require any on-site calibration.
Load Cell
A load cell (force transducer) is a device used to measure force. A
force transducer converts mechanical force into an electrical signal.
The load cell is used to monitor the force applied to the part. It sends
a signal to the DPC to indicate when the mechanical pressure equals
the programmed “Trigger Force”. The trigger is the point at which
the ultrasound is turned on.
The Trigger Force parameter is located on the Process Control Setup
under Trigger Method on the DPC. The values for this parameter
are in pounds or Newtons.
A force versus time graph can be generated if a printer or a computer
with iPC software is connected to the DPC.
The Load Cell is calibrated at the factory. It does not require any
on-site calibration.

Section 5 – Stack/Fixture Setup
Overview
A Dukane press/thruster and a DPC (Dynamic Process Controller)
generator can be used to assemble a unlimited variety of parts for every
conceivable market segment, including Automotive, Medical, Appliance,
Consumer, Packaging and Toy industries. Various techniques and processes,
such as welding, staking, swaging, inserting, and spot welding can be used
for the different applications.
This variety is made possible through the interchange of some system
components. Of these components, the horn and fixture are usually
custom-made for each application, and the booster that is selected for a job
depends on the required horn output amplitude. Also, the press/thruster
controls are specifically adjusted for each application.
This section provides instructions for setting up these components of the
system in a new installation or when changing applications.

•
Transducer
Booster
Horn
The transducer and the booster are normally shipped assembled and
installed in the press. The horn and/or the fixture may be shipped
separately.
The stack is easily removed from or installed in the press/thruster.
This makes it possible to change the horn or booster. It also makes
it easier to perform regular inspections and/or maintenance of the
stack components.

Changing Stack Components
Stack Removal
Before removing the stack, perform the following steps:
1. Activate the Abort switch on the front of the base.
2. Power down the DPC.
These two steps are necessary to ensure that no power will be
accidently applied while removing the stack.
3. While supporting the stack with one hand, loosen the two
socket-head bolts that secure the stack access door.
CAUTION
The stack access door on the press/thruster holds
the stack components in the stack housing. Hold
the stack by the HORN or the exposed part of the
BOOSTER when opening or closing the access
door. This will prevent the stack from falling out
and being damaged.
Figure 5-2Stack Removal
4. Pull the stack forward and down until the transducer clears the
electrical contact. Refer to Figure 5-2.
CAUTION
There may be an electrical charge stored in the
transducer. To avoid any electrical shock, do
not touch the contact button when removing the
stack.
5. Lift the stack out of the housing.
Note:
When changing or inspecting any of the stack components,
ALWAYS remove the stack from the thruster.
Dukane Part No. 403–556–03

Stack Disassembly
To separate the stack component carefully follow the instructions
below:
1. Use the two spanner wrenches (wrench A and B) provided with the
press. Place wrench A on the component to be removed (Refer to
Figure 5-3) and wrench B on the one next to it. Turn wrench A in
the direction indicated.
A
B
Figure 5-3Disassembling Components
CAUTION
To avoid possible injury, press down on the
spanner wrench with the palm of the hand.
Once the component is loose, it can be removed by hand.
2. To maintain structural integrity, NEVER hold a transducer by the
housing or the booster by the mounting rings while separating
components. Doing so will result in damage to the unit.
3. Use only the tools recommended by Dukane. NEVER clamp a horn,
booster, or transducer in a vise or use tools such as pliers, visegrips,
etc.. Doing so will result in scratches and/or gouges, resulting in
stress areas on the surface. This condition will affect the stack
operation and could lead to failure of each stack component.
Removing a Detachable Tip
If the horn has a detachable tip, do the following:
Use a spanner wrench to hold the horn, as shown in Figure 5-4.
Turn a properly sized open end wrench to loosen the tip.
NEVER clamp the horn or use a vice to hold it.

Section 5 – Stack/Fixture Setup
Stack Assembly
Before assembling a stack, inspect all of the components for possible
damage — especially the surfaces that are to be joined. Look for non-flat
surfaces (concave, convex), stress cracks, chips, or gouges. Any of these
irregularities will affect the operation of the stack and could cause further
damage. Contact the Dukane Ultrasonics Tooling Department concerning
a damaged component.
When the components have been inspected and are found to be free of
any damage, continue with the following steps:
1. Inspect the contact surfaces for smoothness and cleanliness. Pitting or
a buildup of old grease and dirt on the surface will interfere with the
transfer of energy from one component to another.
2. Remove any foreign matter from the threaded stud and the mating hole.
Tighten the stud in the stack component that is most distant from the
transducer according to the following stud torque values:

Note:
Do not apply any grease or lubricant to the stud.
4. Thread the components together and tighten (Refer to Figure 5-5) by
applying torque as follows:
For 20 kHz: The applied torque should be 35 ft-lbs (47.4 Newtonmeters) [± 5 ft-lbs].
For 30 kHz and 40 kHz: The applied torque should be 20 ft-lbs (27.1

Installing The Stack
1. With the stack at the angle shown in Figure 5-7, rest the booster
mounting ring on the pin of the stack housing.
2. Brace the stack at point A in Figure 5-7, and swing the stack to a
vertical position. The ultrasound contact button on the transducer
should snap under the electrical contact leaf of the housing.
3. While still supporting the stack in this vertical position, close the
stack access door and thread the socket-head bolts that hold the
door closed into their holes.

4. If the horn is not properly aligned with the fixture, rotate the stack
to align the horn with the fixture.
5. Finish tightening the socket head bolts until snug. DO NOT OVERTIGHTEN!

Fixture Installation
There are three steps involved in installing a fixture.
•
Aligning the fixture with the horn
•
Leveling the fixture to provide the necessary support
•
Rigidly securing the fixture to the mounting surface
Fixture Alignment
To safely align the fixture under the horn, use the following procedure.
(Refer to Figure 5-8.)
1. Depress the Abort switch. This allows the acoustic stack assembly
to be lowered by hand and prevents the system from accidentally
cycling.
2. Turn off the power to the DPC to prevent accidental ultrasound
operation.
3. Place the fixture, with parts, under the horn.
4. Initially align the two slots in the fixture over two of the seven mounting holes on the base plate.
5. Install the two hold-down bolts with washers, and finger tighten.

Note:
The fixture should be flat on the base. If the fixture is
equipped with leveling jack screws, adjust the screws so that
they do not interfere with seating of the fixture on the base
plate.
6. Place a part in the fixture.
7. Grasping the horn firmly, pull the acoustic stack assembly down
until the horn is as close to the part as necessary to align the
fixture.
8. Align the fixture with the horn, and tighten the hold-down bolts,
or caps crews, to prevent the fixture from moving.
9. Adjust the mechanical stop of the press so that the horn stops above
the fixture. This prevents pinch points and avoids horn damage
if the acoustic stack assembly descends when a part is not in the
fixture.
Note:
Some applications may require the horn to be a few
thousandths of an inch from contact with the fixture.
Special applications may require the Mechanical (MEC) stop
to be lowered so the horn makes contact with the fixture or
anvil. When this is required, a ground-detect circuit is needed
to terminate the weld cycle.
Fixture Leveling
For most applications, the fixture must be mounted so that the contacting surfaces on the horn are parallel to the contacted surfaces on the
plastic part. This ensures that a consistent, even weld will result. To
level the fixture, do the following:
1. Place a part in the fixture.
Figure 5-9Loosening the Hold–Down Cap
Screws and Jack Screws
2. Loosen (turn counterclockwise) the hold-down bolts or cap screws
and the four leveling jack screws on the fixture plate. Refer to
Figure 5-9.
3. Pull the acoustic stack assembly down to the fixture. Allow the horn
and the part to align.
4. Turn the four jack screws clockwise until a slight resistance is felt.
Refer to Figure 5-10.
Page 48
Figure 5-10 Tightening the Hold–Down Cap Screws and Jack Screws
Dukane Part No. 403–556–03
Section 5 – Stack/Fixture Setup
5. Tighten the hold-down cap screws by turning them clockwise until
a firm resistance is felt.
Note:
Do not overtighten the cap screws. This may flex the fixture
plate.
6. If any readjustment is necessary, loosen the hold-down screws first.
Then readjust the jack screws.
The following procedure may be helpful in leveling the fixture in some
applications. To perform this procedure, use a piece of carbon paper
and a piece of white paper.
1. Place a sample part in the fixture.
2. Place a piece of white paper on top of the sample part.
3. Place a piece of carbon paper, carbon side down, on top of the
white paper.
4. Enter the following parameters into the DPC:
Weld Time = 0.05
Hold Time = 0.00
Pressure =20-40 psi
System parameters = Use default settings. See examples on Application Setup Worksheet.
5. Set the trigger control on the thruster so that the pressure switch
closes after some pressure is applied.
6. Press the ONLINE button on the DPC.
7. Cycle the equipment by depressing the two activation switches on
the base or by triggering the automation switch.
When one cycle is completed, the pressure developed between the horn
and the sample part will have left marks from the carbon paper on the
white paper. If the fixture is not level, the carbon markings will be darker
in some areas than in others. All carbon markings will be uniform when
all adjustments have been made properly.
Adjust the leveling of the fixture and repeat this procedure as necessary
until you are confident that the fixture is level.

Section 6 – Systems Test
Overview
A Dynamic Process Controller (DPC) must be operating and connected
to the press/thruster in order to test the system.
For efficient operation of a Dukane ultrasonic assembly system, the
ultrasound signal from the Dynamic Process Controller must match the
frequency and phase angle (vibrational characteristics) of the stack that is
being driven. Each stack has unique vibrational characteristics dependent on
the combination of stack components. In addition, the characteristics of a
particular stack may vary slightly during operation because of temperature
and loading factors.
To match the DPC generator output signal with the characteristics of a
particular stack, the generator output frequency is adjusted by Dukane’s
patented Phase-Locked-Loop AUTO-TRAC Pulse-Width Modulation
circuitry.
The AUTO-TRAC feature automatically adjusts the ultrasound signal to
match the vibrational characteristics of the stack being driven. When the
ultrasound turns on during each operating sequence, the AUTO-TRAC
circuit monitors the motion of the stack on a frequency cycle-by-cycle
basis and adjusts the ultrasound signal for the optimum setting. Because
the AUTO-TRAC continuously monitors each operating sequence, it compensates for vibrational changes that occur during repeated operations due
to heating of the stack components. It also compensates for changes that
occur over longer time periods due to aging of the piezo electric crystals
in the transducer, or possible wear of the ultrasonic horn.
The AUTO-TRAC feature excels in environments hostile to reliable
operation, such as high duty cycles or high stress, and continuous-duty
applications. In such situations, the AUTO-TRAC circuit compensates
for the unique vibrational characteristics of each stack due to differences
caused by aging, loading, temperature changes, and differences in horn
configurations.

Model 220/340 Press User's Manual
Operational Test of the
Acoustic Stack
The following test procedure is suggested before starting the DPC
operation, to verify that the vibrational characteristics of the stack fall
within the range of the AUTO-TRAC. All Dukane stack components are
manufactured to tolerance specifications within this range. A non-Dukane
horn, an improperly assembled stack, or a stack component that is worn
or damaged, can result in vibrational characteristics outside these specifications, and will require some adjustment. This test reveals the existence
of any problems and directs you to corrective action.
1. Check the following:
a. Make sure that the correct booster and horn for the application
are installed in the thruster.
b. Check the DPC for proper grounding.
c. Check the ultrasound cable connections on the DPC and thruster
for proper seating and security.
d. Verify that the horn is not under load (not in contact with a
fixture or part).
2. Turn the DPC power switch to ON. The INPUT TEST display will
start to flash on and off for LESS THAN 20 seconds. It will then
turn off and the ON/OFF LINE display will come on. This indicates
that the system is operating (Refer to Figure 6-1).
Note: The system retains the last state (ON LINE or OFF LINE)
that it was in when it was powered down.
Flashes for less
than 20 sec.

If the INPUT TEST display stops flashing but remains on, do not
go any further, there is a problem with the input circuit.
Note: Each time the TEST button is pressed, the display screen
shows the power and frequency of the horn being tested.
Be sure to check the System Power Output display for
verification.

If the power output exceeds the 20% indication, there may
be a problem with the stack.
b. If the OVERLOAD indicator (Figure 6-4) is displayed, a mismatch has occurred between the generator’s ultrasonic output
signal and the stack.

4. While pressing the TEST button, lightly touch the side of the horn
to check for ultrasonic vibrations. If any vibrations are felt, the stack
is operational. If there is no vibration, there may be a problem with
the stack.
If all the indicators pass their tests, the stack is within the AUTOTRAC range.
The DPC is operating at the optimum setting for this stack when the
System Power Output indicator display during this test is between
10 and 20 percent. The vibration amplitude of the horn and booster
and the mass of the horn determine the amount of energy needed
to vibrate the stack.

If the system passes the tests of these 4 steps, proceed to the
section called Running Sample Parts and Making Adjustments.
•
If one or more of these tests have failed, go to the next step.

5. Turn the DPC off. Check the stack for proper assembly, damaged
components, or dirty mating surfaces. Recheck the ultrasound cable
for proper connections. Repeat steps 1 through 4. If the test still fails,
go to the next step.
6. Turn the DPC off, remove the stack from the thruster, and remove
the horn from the stack. Reinstall the transducer-booster assembly in
the thruster and turn the DPC on. Repeat steps 2 through 4.
If the assembly passes with the horn removed, the horn is outside the
specifications required for operation with the AUTO-TRAC preset
range. Reassemble the horn to the stack.
Refer to the DPC manual Section - Hardware Setup. Using the DPC,
select the sub-menu GENERATOR; then select recommended SETTINGS for the software adjustments for PHASE, SOFTSTART and
FREQUENCY. The PULSE WIDTH setting can only be monitored.
Press the DPC TEST button again.

booster and the transducer for the following
•
Any visible damage
•
Loose or cracked stud
•
Pitted or dirty mating surfaces
Make any necessary repairs or adjustments.
Go to step 7.
7. Repeat steps 1 through 6.
•
If the failure indications disappear, reassemble the horn to the
stack and repeat steps 2 through 4.
•
If any failure indications are still present, do not run this stack.
Return the transducer and booster to Dukane for analysis.

Section 7 – Stack Maintenance
Inspection of the Acoustic
Stack Components
It is essential that the mating faces between an ultrasonic transducer/booster
and a booster/horn be absolutely flat and parallel. If there is any air gap,
there will be a loss in power output and efficiency. Coupling may be so poor
as to prevent the startup of vibration from the stack, due to the excessive
power draw at the mating surfaces.
The condition of excessive crowning, or uneven contact surfaces, is
normally made evident by a burnished appearance around the bolt hole
areas of the contact surfaces. This condition indicates that contact between
the parts occurs only at the burnished areas and not across the full faces
of the mating surfaces. (See Figure 7-1.)
Burnished
Area
The following flatness tolerances are specified for Dukane transducers,
boosters, and horns used in 20 kHz applications:
Transducer
.0005 inch
Booster
.0005 inch
Horn
.0005 inch
Figure 7-1Example of Burnished Area
Crown
To check if there may be a flatness problem, first disassemble the stack and
look at the mating surfaces. If there are burnished areas at the periphery
of a contact surface, that surface may be crowned in the center. Place a
straightedge along the face (refer to Figure 7-2). If light can be seen along
the edges, it is crowned.
The surface may also be depressed in the bolt area (refer to Figure 7-3).
In this case, there will be contact only at the peripheral edges and light will
be visible beneath the straightedge in the center region.

Reconditioning Stack
Components
Note:
The operating efficiency of the equipment will be greatly
affected if the mating interfaces of the transducer/booster/
horn stack are not flat, make poor contact with each other,
or become corroded. A poor contact condition wastes power
output, makes tuning difficult, can affect the noise level, and
can cause possible heat damage to the transducer.
To restore the interface to the proper condition, do the following:
1. Disassemble the transducer/booster/horn stack and wipe interfaces
with a clean cloth or paper towel.
2. Examine all interfaces. If any interface is corroded or shows a dark,
hard deposit, it should be reconditioned.
3. If the interfaces appear to be in good condition, go to step 11.
4. If necessary, remove the mounting studs.
5. Tape a clean sheet of #400 grit (or finer) silicon carbide wet-or-dry
paper to a clean, smooth, flat surface. A piece of plate glass is usually
suitable.
6. Hold the part to be conditioned at its lower end with your thumb over
a spanner wrench hole. Carefully stroke the part once in one direction
(toward you) across the abrasive paper, as shown in Figure 7-4. Do
not apply downward pressure. The component’s weight alone provides
sufficient pressure. Perform a second stroke.
IMPORTANT
Use extreme care to avoid tilting the part. Loss of flatness
of interface surfaces may render the welding system
inoperative.
Figure 7-4Method of Component
Resurfacing
7. Rotate the part 120° (1/3 rotation) to the next spanner wrench hole.
Repeat the procedure outlined in step 6.
Page 62
Dukane Part No. 403–556–03
Section 7 – Stack Maintenance
8. Rotate the part the remaining 120° and repeat. Be certain to perform
the same number of strokes at each orientation: Two strokes per
rotation.
IMPORTANT
Use extreme care to avoid multiple strokes at each 1/3
rotation of the part. Loss of flatness and perpendicularity
of the interface surface to the centering axis of the part may
render the welding system inoperative.
9. Before reinserting a stud in any horn, perform the following for proper
engagement of the threads:
a. Visually inspect and clean the stud.
b. Clean the threaded hole using a clean cloth or towel.
c. Tighten the stud to the torque specifications listed in Table 7-1.
Note:
Thread deformation may occur if the studs are overtightened.
Removal of the stud could damage the threads in the horn.
If this occurs, re-tap the horn threads and replace the stud
with a new one. Use studs recommended by Dukane.
10. Reexamine the interface surface and repeat steps 6 through 9 until most
of the contaminate has been removed. This should not take more than
2 or 3 complete rotations of the part being reconditioned.
11. Reassemble and install the stack, using the procedure in Section 5 of
this manual. Recheck the power supply tuning. See Section 6, System
Test.
Torque Values
The correct torque values for stack component assemblies are as
follows:
•
The torque values for the transducer/booster/horn assembly for:
20 kHz = 420 inch-lbs./35 foot-lbs. ± 5 ft-lbs.
30 kHz and 40 kHz = 240 inch-lbs./20 foot-lbs. ± 5 ft-lbs.

Maintenance
1. Disconnect the generator AC power cord from the AC line receptacle. Then, remove the thruster left and right side covers.
2. Check that all socket-head cap screws in the press/thruster are tight.
Check the air cylinder mounting.
3. Wipe or blow away all dirt and grease in the press/thruster.
4. Wipe away all excess oil and any dirt accumulation, especially at the
exhaust openings in the transducer housing. There should be very little,
if any, oil accumulation at the air exhaust opening. We recommend that
no oil get into the press/thruster pneumatics. Regular accumulation
of oil at the air exhaust opening means that some oil is getting into the
pneumatics. To rectify this problem, route the air for the press/thruster
through an “oil mist reclassifier”.
5. Check the press/thruster slide operation for smooth downward motion.
Wipe away any accumulated grease, but do not apply any solvents. If
movement is not smooth, the lower bearing may be greased with AFB
lithium grease in the standard grease fitting provided.
6. Ensure that all wire and cable connections are secure in the press/
thruster and are not rubbing or showing wear. If they do show wear
or rubbing then reroute to eliminate the problem.
7. Remount and secure the press/thruster covers and reconnect the generator AC power cord to the AC line receptacle.

Prototype Renshape 460 (Renwood) tools employ
reusable content, and therefore remain the property
of Dukane.
All Dukane warranties commence on the date of the original shipment of the equipment or tooling, and duration is based upon a single shift
per day, five day per week operation. The warranty period on rentals of new equipment that are converted to a purchase are deemed to
have commenced on the initial date of rental.
These warranties are limited to equipment and tooling operated and maintained per Dukane’s written instructions, and used under normal
operating conditions. These warranties do not include normal wear or normal wear items, and do not cover damage attributable to misuse,
improper installation, faulty repair, unauthorized alteration or modification, neglect, or accident. Misuse includes operation of equipment with
tooling that is not qualified for the equipment or properly installed on the equipment.
The warranty on all Dukane equipment and tooling purchased and installed in North America is a parts and labor warranty only. Equipment
installed outside of North America, regardless of where it was purchased, is covered by Dukane’s International Warranty Policy. In all cases,
when on-site service is required, Travel & Living (T&L) expenses will be billed at cost. Warranty service labor (including travel time) at the
customer’s site is provided on a Monday through Friday (excluding holidays), 7 a.m. to 7 p.m. basis. Any warranty service requested outside
of these hours is available on a charge basis equal to 150% of Dukane’s prevailing rate for technical service work.
Any equipment or tooling that proves to be defective in material or workmanship during the stated warranty period will be repaired or replaced
at the sole discretion of Dukane Corporation when Dukane is promptly notified in writing. During the warranty period, defective equipment,
components, or tooling that are returned properly packed with all transportation charges prepaid will be repaired or replaced and returned to
the end-user without charge. Shipments of warranty parts will be via standard, non-expedited delivery service. Expedited shipment requests
are subject to freight charges to the Purchaser.
Computers, PLCs, CRTs, LCDs, touch screens, and keyboards separate and/or incorporated as an integral part of a system will carry a one
(1) year warranty from the date of shipment when used under normal operating conditions, and not subjected to misuse, abuse, or neglect.
For all other equipment, components, or parts included in equipment or systems from Dukane, but not manufactured by Dukane or its affiliates, this warranty shall be limited in time and extent to the warranty given to Dukane by the OEM.
EQUIPMENT WARRANTY EXCLUSIONS OR EXCEPTIONS:
When specified in our quotation, a limited warranty may apply to certain components of the equipment, and/or for certain types of applications of the equipment, including those noted below.

Section 13 – Glossary of Terms
Amorphous Plastic
A thermoplastic which has a random molecular structure (e.g. ABS,
Polycarbonate, Polystyrene).
Amplitude
The peak-to-peak excursion of a horn or a booster at its workface. It
is usually measured in tens of microns or thousandths of an inch.
Booster
A mechanical transformer used to increase or decrease the amplitude
of the horn vibrations.
Boss
The hollow stud into which an insert is driven.
Dampen
To mechanically limit the amplitude of vibration in the parts being assembled.
Degating A process by which injection- molded plastic parts are removed from
the runners and sprue at the gate.
Diaphragm Damage
Part flexing that can cause stress, fracturing, or undesirable melting of
thin-sectioned, flat parts. Diaphragm damage is also referred to as “oilcanning,” which describes the way the plastic part bends up and down
when subjected to ultrasonic energy.
Digital Timer
A device used to accurately control the duration of a weld or a hold
time by signaling the value to the acoustic stack assembly to extend and
retract the horn and by activating the ultrasound for a predetermined
time span.
Dual Pressure
A feature of Dukane ultrasonic assembly systems that allows the use of
two different pressures during the assembly (welding, inserting, staking,
etc.) process. Typically a weld is started at lower pressure and finished
at a higher pressure.
Encoder
An electronic device that accurately measures distance or angle of rotation.
Energy Director
A triangular-shaped ridge of plastic molded into a part and typically
running around the entire perimeter of a joint. When ultrasonic energy
passes through the ridge, it concentrates the energy at the director’s apex,
resulting in rapid heat buildup, melting, and subsequent welding of the
parts.
Far Field
Refers to the distance that ultrasonic energy is transmitted from the
horn to the joint interface. When the joint is more than about 0.25 inch
or 6mm from where the horn contacts the part, the weld is considered
far field. (see Near Field).
Filler
An inert substance that is added to a resin to modify its physical
characteristics.
Dukane Part No. 403–556–03
Page 113
Model 220/340 Press User's Manual
Fixture
A device used to align and support the parts to be assembled. It is
sometimes referred to as a nest.
Flash
The overflow of plastic from a welded joint area.
Frequency
The number of cycles per second measured in hertz (Hz).
Gain
The ratio of output amplitude to input amplitude of a horn or a booster.
When the gain is greater than one, the output amplitude is larger than
the input amplitude.
Gate
The area through which molten plastic flows into the mold cavity. Also
see Degating.
Generator
An electronic device that converts standard 120/240 volt, 50/60 Hz
line voltage into high-frequency electrical energy.
Hermetic Seal
An airtight and liquid–tight seal.
Hold Time
The length of time allotted for the melted plastic to solidify.
Horn
An acoustical tool designed to transfer mechanical vibrations from
the transducer-booster assembly directly to the parts to be welded
together.
Hygroscopicity
The tendency of some thermoplastic materials to absorb moisture
from the air. Nylon is very hygroscopic.
Hz or Hertz
Cycles per second. Ultrasonic waves are measured in kHz or thousands
of cycles per second.
Insert
A metal fastener designed to be installed in a plastic part.
Insertion
An ultrasonic assembly technique that embeds a metal insert into a
plastic part.
Joint Design
Molding the shape of mating thermoplastic parts to achieve the intended
assembly results. Proper joint designs provide a uniform contact area,
a small initial contact area, and a means of aligning the mating halves
to be welded together.
Load Cell
A transducer that measure applied force and coverts the force into an
electric signal to allow precise force measurements.
Marking
Cosmetically scuffing or marring of plastic parts by the horn or the
fixture.
Page 114
Dukane Part No. 403–556–03
Section 13 – Glossary of Terms
Mold Release
A substance added to plastics so that parts are easily removed from the
mold.
Near Field
Refers to the distance that ultrasonic energy is transmitted from the
horn to the joint interface. When the joint is less than about 0.25 inch
or 6mm from where the horn contacts the part, the weld is considered
near field. (see Far Field).
Nodal Point
The point in a booster or horn where little or no linear motion (due to
the ultrasonic wave) occurs.
Piezoelectric Material
A ceramic material that emits electrical charge when force is applied
or changes dimension when electric energy is applied.
Pneumatic
Powered, operated, or controlled by compressed air.
Polymer
A chemical compound or mixture of compounds formed by a chemical
reaction of two or more molecules. Polymers are also called resins.
Press
A pneumatically-operated device used to transport the acoustic stack
assembly to the work in a controlled and repeatable manner. It is essentially a thruster mounted on a column, press support casting, and a
base. (Also see Thruster.)
Regrind
Plastic material that has been recycled or reprocessed and added to the
original resin.
Replaceable Tip
A machined titanium tip threaded to attach to a horn. Tips are commonly used in staking, swagging and spot welding assembly.
Resin
See Polymer.
Resin Grade
Refers to the classification of the physical and chemical properties of
a resin.
Semi–Crystalline Plastic
A thermoplastic which has an orderly and repeated molecular structure
(e.g. Nylon, Polyethylene, Polypropylene).
Shear Joint
A joint design formed by the controlled, telescoping melt of two contacting surfaces. A certain amount of interference must be designed
into one of the mating parts to accomplish the weld.
Sound
Mechanical, radiant energy (vibrations) that is transmitted by longitudinal waves in a material medium, such as air, water, or metal.
Dukane Part No. 403–556–03
Page 115
Model 220/340 Press User's Manual
Spot Welding
An ultrasonic assembly method where two thermoplastic components
are joined at localized points. The components joined by spot welding
are typically cast or extruded.
Staking
An ultrasonic assembly technique by which a plastic stud is formed
into a rivet head to capture another part, which may be of a dissimilar
material.
Stud
The plastic protrusion that is shaped into a rivet head to attach two
parts together during staking.
Swagging
An ultrasonic assembly technique by which a ring or a ridge of plastic
is formed by the horn face to capture another part.
Thermoplastic
A synthetic or manufactured material which softens when heated and
harden when cooled. A thermoset plastic undergoes an irreversible
change during processing and become permanently formed.
Titanium
A high–strength metal with good acoustic properties used in the
manufacture of horns and boosters. The titanium used for horns and
boosters is an alloy with enhanced properties.
Thruster
A pneumatically-operated device serving the same function as a press.
A thruster can be mounted in a smaller area or otherwise nonstandard
position. (Also see Press.)
Transducer
A piezoelectric device that converts high-frequency electrical energy
into matching high-frequency mechanical vibrations.
Tuning
The process of matching the output frequency of the generator to the
resonant frequency of the transducer-booster-horn assembly.
Ultrasound
Mechanical vibrations having the same physical nature as sound, but
with frequencies normally above the range of human hearing (above
20kHz).
Ultrasonic Sound
same as Ultrasound
Weld Time
The length of time the parts to be assembled are exposed to the ultrasonic energy.
Welding
An ultrasonic assembly technique that uses the heat of friction to bond
thermoplastic parts.

Section 1 – Introduction Dukane ISO
ISO CERTIFICATION
Dukane chose to become ISO 9001:2000 certified in order to demonstrate to our customers
our continuing commitment to being a quality
vendor. By passing its audit, Dukane can assure
you that we have in place a well–defined and
systematic approach to quality design, manufacturing, delivery and service. This certificate
reinforces Dukane's status as a quality vendor
of technology and products.
To achieve ISO 9001:2000 certification, you
must prove to one of the quality system registrar groups that you meet three requirements:
1. Leadership
2. Involvement
3. Quality in Line Organizations and Quality
System Infrastructure.
The ISO 9001:2000 standard establishes a
minimum requirement for these requirements
and starts transitioning the company from a
traditional inspection–oriented quality system
to one based on partnership for continuous
improvement. This concept is key in that Dukane no longer focuses on inspection, but on
individual processes.
Dukane's quality management system is based
on the following three objectives:
1. Customer oriented quality. The aim is to
improve customer satisfaction.
2. Quality is determined by people. The aim
is to improve the internal organization and
cooperation between staff members.
3. Quality is a continuous improvement.
The aim is to continuously improve the
internal organization and the competitive
position.
ISO 9001:2000

Dukane products are manufactured in ISO
registered facilities
