The manual bayonet clamping systems consists of a clamping
adapter plate that is bolted to each platen using existing Euromap
threaded holes. On the stationary side of the mould the existing
locating ring is replaced by one of our bayonet centering adapters.
The moveable side of the mould will also require a bayonet
centering adapter. When loading the mould into the machine
the stationary side bayonet adapter is pushed into the stationary
clamping plate. The mould is located on the machine platenlocating ring. The mould is locked in place by a simple 53 degrees
rotation of the lever. The machine is closed and the process is
repeated on the moving side. The systems are suitable for moulds that weight up to 2 t and injection moulding or rubber moulding machines up to 250 t capacity.
The clamping adapter plates are 17 or 22 mm thick with centering
ring sizes of 100, 110, 125 and 160 mm. The manual system
does not require mould standardization other then mounting of the
bayonet adapter rings. Bayonet adapter rings are also available
for tools with insulating plates.
EAS Manual Clamping Solutions
for SPI Platen Standards
Manual clamping solutions are available for SPI machines with multiple ejector bar holes. These systems
utilize a rack and pinion to rotate the lock ring to clamp the
mould in place. The SPI manual clamp systems are equipped
with removable handles. SPI clamping plates have a thickness
of 1" inch. Bayonet adapter rings are available in a variety of
spi machines

The WS series clamps utilize an wedge system, which
allows a greater tolerance on
the back plate thickness.
Clamps come equipped with 2 proximity switches to indicate
the clamped and unclamped positions. This series of clamp
also requires standardized mould back plates.
Clamps are available in the following capacities:
80, 200 & 350 kN.
mod / wod / nod series
A typical quick clamping system consists of 4 or more double acting hydraulic clamps, which are mounted to both platens. The clamp
plungers are angled at a 5 degrees to provide a self-locking feature. Pressure does not have to be maintained for the clamps to remain locked
providing additional safety during the moulding
EAS offers two series of self-locking wedge
clamps: MOD/WOD/NOD series with the
5 degrees plungers and the WS series, which
uses an internal, wedging feature. Both series
clamp on flat back plates and come equipped
with 2 proximity switches to indicate the clamped
and unclamped positions.
The MOD series is the metric version for use on Euromap
standard machines and feature metric mounting patterns and BSP oil connections.
The WOD series is the imperial version for use on American
SPI standard machines and feature imperial mounting patterns
and SAE oil connections.
The NOD series is available for the Japanese market
The back plates of the moulds that are used with these series
of clamps must be standardized because the clamps will be
fixed to the platen. Clamps selection is determined by dividing
the opening force of the machine by the number of clamps. Example: A machine with an opening force of 800kN (80 t)
would need 4 clamps per platen, each with a 200kN (20 t)
capacity or the MOD/WOD/NOD 2010. Clamps are available in the following capacities:
15, 30, 60, 110, 200, 400 & 1200kN.
Standard temperature range: 60º C (140º F)
High temperature seals and proximity switches available on request.

and the mould is clamped on the fixed platen. The movable
platen is then closed and the movable platen clamps are then
activated. The mould is now securely clamped.

Centering rings are not required when using standardized back plates.
 Movable clamps
Movable clamps can be used when fully
standardized back plates are not feasible.
MOD/WOD/NOD series clamps can be made movable in T-slots. This movement can be accomplished manually or
automatically using a pneumatic or hydraulic cylinder. When done automatically the clamp sensor will determine if the clamp has reached the back plate. The cylinders are mounted on long T-nuts for accurate movement in the T-slots. It will still be necessary to standardize the back plate
thickness at the clamping points as well as the height from the base to centerline if a mould stop locator is used.
 Vertical Load & Rotate
Large moulds are often wider than the tie bar gap but must be rotated between the tie bars when loaded vertically.

Each mould would have the corresponding number of EEB
clamping bolts mounted to each side of the mould.
Clamping is achieved when the hydraulic cylinder moves the wedge on the end of the plunger into the matching wedge shaped slot in the clamping bolt.
On small injection moulding machines only 2 hydraulic
cylinders per platen are required for clamping. On larger
machines (up to 2500 t), 4 hydraulic clamping cylinders per platen are required to handle the forces defined by
Euromap 11 and VDMA specifications. On very large machine 8 hydraulic cylinders are required to insure trouble
free clamping.
Location of the clamping cylinders and clamping bolts must be standardized, and utilizes the centering ring for final mould location.
The integrated hydraulic system can be applied to any new
machine where the platens can be easily modified to accept
the system. These platen modifications do not make it
applicable for retrofit to existing machines.

The integrated hydraulic clamping system
(Engel System) is mounted to the sides of the
platen, leaving the platen face completely free
of obstructions. Depending on machine size the
mould is clamped using
2, 4 or 8 clamps per platen.
No standardization of the mould or back plates is required
except for mounting of the clamping bolts. The full platen area can be used for larger moulds.
For horizontal load mould change the mould is moved in over
rollers and uses a mould stop for final position.
For horizontal loading the mould must be standardized for the
bottom to the centerline for proper alignment.
The closing movement of the machine will push the clamping
bolts into the platens. This movement can also be used
connect the multi-coupler systems.
To pull the clamping bolts out of the platens, the opening of
the machine can be used or additional push cylinders can be
mounted to the machine.

Ideas come from EAS:
Serving the Quick Mould Change (QMC) market for more than
20 years, EAS listened carefully to it’s customers to find better
solutions for, YOUR QMC, JIT and SMED needs.
The primary advantage of the magnetic clamping system is that
it avoids the need for standardized back plates for vertically
loaded moulds. EAS has optimized their new range of electro
permanent magnetic clamping solutions which support:
demand for full electric injection moulding
need for safe systems with sufficient holding force
extra safety device when required
reduction in daylight opening
Following the acquisition of the Pressmag “know-how” from
Braillon - the original inventor of the electro magnet - EAS
optimized it’s range of magnetic clamping systems by using
both the benefits of the square pole design and the long pole
design for the right application for you, our customer.
The EAS solutions:
n For small sizes of injection moulding machines (<800T) it is important not to lose much daylight opening due to thick magnetic plates. But at the sametime maintain the required clamping forces, despite ejector holes. For these reasons we developed the small 45 mm square pole design (but round at the surface) with only 38 mm (1.5”) plate thickness, the PRESSMAG SP and
n for larger sizes of machines we optimized and
standardized the PRESSMAG HP system working with standard long poles, resulting in high magnetic flux concen-
tration with superior clamping forces. The thickness of these systems is 55 mm (2.16”).
n for alloyed steels and/or for complete demagnetizing PRESSMAG T and
n for high temperatures till 250° C or 464° F the PRESSMAG HT.

The EAS ejector couplers include a floating design to
accommodate larger misalignment between the ejector
coupler and the male adapter, which is mounted to the
mould ejector rod.
Designed to VDMA 24465 part 5 standards. Hydraulically
operated, single acting design. Life expectancy of 2 x 10(6)
cycles at 50% of specified forces on the ejector coupler. Two
proximity switches to indicate coupled and uncoupled position.
Floating design allows 1mm of misalignment correction.
The ejector couplers can also be operated pneumatically at
reduced forces. Please consult EAS for pneumatic applications.
Available in 20, 50, 100 & 200 kN capacities.
For machines with American SPI platen
configuration EAS has designed SPI ejector
couplers which can be used with the 1" and 2"
SPI ejector patterns without platen modification.
Available in 1" or 2" diameter sizes the SPI ejector couplers
simply push together, connecting the machine ejector to
the mould ejector when the mould is loaded. When the
mould is to be removed the ejector couplers are hydraulically
pressurized to release. (WCE 10 can also be operated
Our WCE 52 ejector coupler features an optional proximity
switch to provide a confirmation signal to the machine controls.

FOR retrofitting
existing machines
Retrofit solution with control unit
and satellite boxes
When the hydraulic clamps can not be
powered by the machine tool hydraulic system,
an independent pump and valve packages can
be installed to provide the hydraulic power
requirements. These pumps are often used on
retrofit systems.
Another advantage is that when the machine is down, the
mould change can still take place as the pump unit and
controls are independent of the machine. For the MOD- and
WS -series of clamps, a mobile pump unit can be used for
several machines as hydraulic pressure is not required when
clamped but only at the time of the mould change. EAS have
experienced installation crews to install these systems.
Satellite box SBL-14 and SBR-14
These boxes collect proximity switch signals from the hydraulic
mould clamps. SBR-14 for 4 clamps, SBL-14 for 4 clamps plus the ejector coupler.

Quick mould change systems
Mono couplers
Manual multi couplers
Automatic multi couplers
This is an example of how fluid connections
are often done, resulting in inefficient cooling,
leakage and high scrap rates.
The leak-proof EAS manual multi couplers are
available in standard versions with 6 and 12 mono
couplers. A variety of hose connection sizes and
configurations are available for the mould half
multi couplers.
These high quality leak-proof water couplers can also be
combined with air, hydraulic and electrical connectors to
provide quick connections for all of the moulds utilities.
Here is an example of the correct way of
connecting several fluid circuits, without the risk
of leakage or misconnenction. When used in
conjunction with a good water treatment system,
EAS multi couplers will reduce scrap and improve
the quality of your production.
Two standard manual multi couplers with 12
water connections, a special manual multi
coupler with 5 electric connectors for signals and
heating purposes and one special manual multi
coupler for hydraulic core pulling connec­tions are
mounted on these 40 t moulds.
The fluid and electrical connections are done
within 3 minutes and without leakage of water or
oil, which keeps the area very clean.
A simple parking station is provided to hang the machine side
multi coupler during mould change, avoiding coupler damage.
With these coupler solutions, fluid and electrical connections
can be made in a few minutes while keping the floor and the
system clean.
EAS can also supply a complete range of open
and closed multi couplers which are completeley
interchangeable with a leading competitive brand.
We can also supply a variety of interchangable
mono couplers some
well known brands.
A manual mullti coupler with several electrical
connectors for heating and sensor signals.
A standard 12 connection multi coupler, with size
12 (1/2”) water connections is used for the cooling
circuits. A park station is used for hanging
the manual multi coupler during mould change.
These multi couplers solutions were implemented
on five 1300 t machines.

simple, leak proof and fast
connection of all your fluid and
electric connections
Multi couplers can be used with different EAS
Most applications use our leakproof self locking couplers type
CQF and CQM, where the two multi coupler halves are locked
together by each individual mono coupler. These couplers
are available from size 6 to size 37 up to 900 l/min and for
hydraulics up to 200 bar pressure. Special connect under
pressure couplers are also available.
This 2700 t injection moulding machines with horizontal
loading, has standardized multi couplers on the movable and
fixed side of the machines. Connections for cooling water,
hydraulics for core pull cylinders and electric for heating and
signals, are automatically connected and disconnected.
This connection takes less then 30 seconds.
All couplers feature the leak proof couplers, keeping floor and
envirement clean.
The advantage of self locking couplers:
Self locking couplers contain the separating forces which occur
when pressurized. By containing these separating forces within
the body of the coupler we are able to reduce the stress on the
coupler plate and cylinders.
The other advantage with our CQF/M couplers is that if
the mould is not in the machine, each coupler can still be
connected for testing purposes.
Because of the leak proof design we can combine water, air,
hydraulic as well and electric connections into one automatic
multi coupler.
EAS also offers standard VDMA multi couplers. The number,
position and arrangements of energy connections for automatic
changing of injection moulds are specified and standardized
according to VDMA 24464 and Euromap.
This multi coupler system for horizontal loading connects
water and electric connections trouble free in less than 20
seconds. Another advantage of these multi couplers is that
misconnections are being made any longer, which reduces
the amount of bad products.
Large size 37 mono couplers are part of the multi
couplers on this machine to connect leakproof large
cooling lines. This in combination with heating oil
connections and electric connections results in a
total mould change time of less than 15 minutes in
combination with hydraulic clamping and a vertical
mould change by means of an overhead crane on this
2300 t machine. Fast, safe and clean.

Manual mould handling systems
a simple horizontal way
of changing moulds
Transferring the mould into the machine can be
done manually or must be powered in depending
on the weight of the mould. When the mould is
light enough, manual transfer is practical.
EAS offers the following solutions:
Our manual
mould change
car for one
mould of max.
800 kg.
A manual car is used to transport the moulds from the storage
area directly into the machines. The adjustable height feature
uses a hydraulic hand pump and cylinders to raise and lower
the bed. The car can accommodate one 0,8 t or two 0,5 t
moulds. When the car arrives at the machine it is positioned
to allow the existing mould to be manually pulled out of the
machine. To support the mould between the cart and machine
a set of bridge rollers are manually lowered. Once the mould
has been removed the car is then positioned to allow the new
mould to be manually pushed into the machine. The bridge
rollers are then raised up out the way and mould is transported
back to the storage area.
EAS can offer different solutions depending on mould size
and space limitations. Cars can be configured for side load or
end load operation depending on the plant layout.
Both configurations speed the mould change process.

When the moulds are too heavy to be transported
manually, a battery powered car with hand controls
can be the solution. These cars can be equipped
with variable height roller decks to accommodate
different size machines and storage system levels.
Manual or powered push-pull mechanisms are available to
transfer the moulds in and out of the machine or storage system.
These powered transfer mechanism can be operated electrically
or with air.

Mould locks keep the mould from moving on the roller deck
when the car is in motion. These cars handle one or two moulds
with a combined weight of 25 t and come equipped a battery
charging system.
A two station mould change car can complete a mould change
in less then 5 minutes when used with the press mounted
roller and clamp system.
When docking the car to the machine is difficult due to
space limitations, EAS can supply a combination battery
powered drive and air cushion car. For normal transport the
battery drive is used. Once at the machine where space and
maneuverability are a problem, the air cushion system is
connected to the air supply and the car is easily floated into
the exact position for loading.

Mould change tables
for small and large moulds
up to 200 ton weight
Single station mould change tables dedicated to
an injection moulding machine. They are used
when horizontal loading is required and moulds
are changed infrequently or space is not available
for two station mould change tables (see the next
pages for multi station tables).
These tables can use a manual or powered transfer mechanism
depending on mould weight to load and unload the machine.
The powered transfer can be equipped with an automatic push button control.
On an Italtech 2500 t injection moulding machine EAS delivered the horizontal
hydraulic adaptive clamping systems and a mould change table for moulds of
maximum weight of 40 t. Guides on the table allow the crane driver to easily
position the large mould in a simple way on the table. An air driven push-pull
spindle device moves the mould in and out the machine. All water, hydraulic and
electric connections are made with manual multi coupler systems.
A Windsor 3000 t injection moulding machine is equipped with an adaptive
horizontal hydraulic clamping system, an ejector coupler, automatic multi couplers
and a mould change table for one mould of maximum weight of 35 t.
The operator controls manually the different steps of the mould change.
When using a single station change table you must first pull
the mould from the machine and remove it from the table
by overhead crane or fork lift truck. The new mould is then
positioned on the table roller deck. The new mould is then
pushed into the machine. These tables are used in conjunction
with clamp and roller systems in the press (see page 12 & 13).
The time required to do a complete mould change is depending
on the size and weight of the mould. For example, a 40 t
mould could be changed in less then 20 minutes.
A table for 1 x 20 t mould with on one side the rollers with mould guidings, while
on the other rollers moulds with different dimensions can be placed.
This table has a fixed operation panel. This table also features two guides
to enable the crane operator to position the mould easily on the table.

This 800 t machine is
equipped with hydraulic
clamping system with rollers
and with automatic multi
couplers. A mould change
takes place in less then
4 minutes and this system
had a return of investment of
6 months.
Mould changes with a two station mould change
table are faster then a single station mould
change table because the mould is pre-staged
on the table. Additional time can be saved by
pre-heating the mould on the table.
When changing a mould the mould in the machine is pulled on the empty station on the table. The table is then shuttled to position the new for loading. The new mould is then pushed
into the machine. EAS provides powered transfer mechanisms
which load from one side of the table or both sides of the table.
Powered roller transfer is also available. This system utilizes
powered rollers on the table and in the press to provide the fastest method of changing moulds.
When mould change tables are used with 2 presses they
increase your flexibility to run smaller production batches and
reduce inventory. Side load systems increase safety for the
operators because the mould is always supported and guided
during the change. Mould change tables can be equipped with
Programmable Logic Control (PLC) system which allows manual,
semi-automatic or fully automatic operation.
Automatic operation requires interfacing with the machine
controls, and they are most often applied on new machines.
Mould change table for two moulds of max 2 x 15 t, with an
overhead push-pull device. This table features a pre-heating
station with automatic multi couplers connections and was
placed next to 800 t machine and a 1300 t machine.
This mould change table , which can handle two 20 t moulds,
has been fitted with a pre-heating unit; this allow pre-heating
or the moulds outside the machine, so that valuable production
time is not lost by heating the moulds while it is in the machine.
Integrated multi couplers ensure automatic connection of all
liquid and power supplies.
Mould change tables are often equipped with a hydraulic
power unit to power table movements as well as clamping,
ejector couplers and multi couplers.
On this 1000 t machine this table for
2 x 10 t moulds enables the operator
to change moulds within 6 minutes.
Each mould position features a telescopic push pull device for a fast transfer into
the machine. At the end of each device is a pneumatic mould gripper to connect
the push pull device to the mould automatically. Each mould need to be equipped
with an adapter.
Mould change tables, positioned between two presses
mould change tables increase
your flexibility, speed and safety
When using a mould change table betwen two
injection machines you will improve your return
on investment because the table is suporting two
machines instead of one. This provides greater
flexibility and faster changeover.
EAS has implemented solutions with overhead push/pull devices,
telescopic push/pull devices to load from both sides of the
table as well as powered rollers. Powered rollers provide the
fastest changeover because you do have wait for the push/pull
device to travel into the machine.
At this application a mould change table was placed in between two 2700 t
injection moulding machines and is able to carry two 40 ton moulds. The moulds
are loaded and unloaded on the table by an overhead crane. The table is
equipped with pre-heating multi couplers, allowing the new mould to be heated
prior to its movement into the machine, saving hours of unproductive time.
At this application EAS selected an overhead transfer mechanism, which is
mounted over the table and on the two machines. Each mould is equipped
with two connection bars, mounted on top of the fixed side of the mould.
With this solution a mould change can be done within 10 minutes.
Note; If no overhead crane is available to load and unload the moulds on
the table, the table can be equipped as a rail guided car. This table-car brings
the moulds then to storage positions where several moulds can be stored.
The moulds are equipped with standardized
mould backplates. The fluid and electric
connections are well organized and being
connected by automatic multi couplers.
Three 3000 t machines are configured with mould change tables in between.
These powered roller mould change tables can transfer a 40 t mould into either
machine at the push of a button. This provides speed and flexibility to the
moulding process.
EAS equipped the machines with powered rollers and clamping systems.
EAS installed the complete system including platforms, stairs and mould change
table control systems. The operator has acces to the top of the table form the
platforms. Safety gates prevent people from walking on the table during the
mould changes.
Production cells
For your complete
automated production
Completely automated production cells can
run very smal batches before changing over for
the next run. These 2, 3 or 4 station change
tables include pre-heating features and change
moulds automatically.
The moulds can be loaded onto the table by overhead
crane or fork lift truck by opening the safety gate.
The EAS production cells consist of clamping systems,
ejector couplers and multi couplers on the machine and the multiple station mould change table with pre-heating
system, all operated by PLC controls and on board
hydraulic sytem.
A fully automatic production cell with pre-heating station working with a 250 t
injection moulding machine.
EAS can also provide standardized mould back plates,
mould side ejector coupler adapters and multi couplers.
In most applications we work closely with the machine
manufacturer to interface cell controls with the machine
A 150 t machine with a 2 way 3 position mould change table, pre-heating,
multi couplers, hydraulic adaptive clamping and an ejector coupler.
The pre-heating equipment is stored under the table and can be easily reached.
Rail guided mould change cars
Mould change car travels
within rows of machines
and storage systems and
pre-heating stations,
changing to both sides
of the car.
Mould change car
to pick up moulds
from the storage
and to bring to one
or more machines.
Quick, safe and simple
for moulds up to 200 ton
A further step towards automation is the
installation of a rail car system to serve one
or more injection moulding machines in a
complete line of machines.
2 x 20 t car with height adjustment
This usually means a complete reorganization of the plant
and is most often done at new plants. The mould change
car transports the moulds to and from the storage and or
pre-heating stations. Unlike the mould change tables, the cars are not equipped to activate the requisite clamping
and energy coupling operations. The cars can be battery
powered or by an overhead power rail or by a cable trolley;
in most cases the option is determined by the rail length
and the normal frequency of mould changeovers.
The cars are equipped with positioning devices for exact
positioning along the machine or at the storage rack. They can be equipped by a manual or an automatic
connection for the machine interface. The mould change
device can load one side of the car or to both sides of the
car in case the car travels in between rows of machines.
Economy versions are equipped with spindle push/pull
devices. More advanced cars are equipped with telescopic
push/pull devices with automatic mould grippers.
2 x 40 t car in between 7 machines
For safety purposes, each mould roller bed is equipped with
a mould lock, which holds the mould on the car during
transport along the machines. Safety bumpers, acoustic or light signals can be part of the car. The cars can be
operated manually, semi automatic or completely automatic.
The operator can either walk along with the cars or drive
on the car from an operator platform. For different sizes of
machines the car can be equipped with height adjustment.
Loading and unloading of the moulds can be done from the storage systems or by an overhead crane. The storage
systems can also be loaded by an overhead crane or by a fork lift truck.
Mould change times for 40 t moulds can be accomplished
in 10 minutes with these solutions.
Air floating mould change cars "System Aerogo”
Air floating cars actually
float on air film like a
hovercraft and are therefor
very flexible in moving
around pillars or in restricted
areas and can carry very
heavy loads.
Easy movements of heavy loads
Air floating cars actually float on a thin film of air
like a hovercraft whih provides great mobility in
restricted areas. They can also carry very heavy
loads without special floor reinforcement.
A 110 t mould is transported from its storage system to the injection moulding
machine or inspection unit. This customer, a producer of large plastic container,
had no overhead crane available for such heavy weights and this solution enables
them to change these moulds within 35 minutes. The push pull mechanism is
a simple spindle device, which pushes or pulls the moulds in or out the large
twin machine.
An air floating car can be in interesting alternative to rail guided
mould change cars. They easily move very have loads (up
to 200 tons or more) in tight spaces while providing greater
flexibility in plant layout then a rail system. The floor must have
the cracks filled, be sealed, and level for the best performance.
A suitable air compressor is required with an appropriately sized
air hose. For greater range without several connections points,
an air compressor can be placed on board the car. Noise level
is surprisingly low.
The upper roller deck is the same as a rail guided cart and
features the same style of transfer devices, guides and mould
locks. They can be loaded from a mould storage rack or by
overhead crane.
Air floating cars can be easily positioned in front of the machines
with docking rails and locked to the machine. They can be
controlled by a pendant control panel or by radio control.
Air powered drive wheels control the speed and direction of
the cart while the cart is moving. Space is very limited around the machines at this automotive supplier, two air
floating cars for 2 x 20 and 2 x 15 t moulds are used to change these moulds in
less then 15 minutes. The push /pull changing device can change the moulds to
both sides of the car, which brings even more flexibility and speed.
For extreme heavy moulds as at this container manufacturer EAS installed
this air floating system in combination with storage systems, a 3400 t and
a 6000 t injection moulding machine as well as an EAS inspection unit.
The car can handle up to 150 t moulds and the change over time is less
then 30 minutes.
Air floating solutions can be very attractive for smaller mould handling
requirements. It can also be combined with an electric drive system to travel
longer distance. The operator can walk behind or even sit on board.
Contact EAS for very creative solutions to your mould handling problems.
Customized solutions
easy movements of heavy loads
Special presses or other unusual circumstances
lead sometimes to inventive solutions by EAS as
the picture on page 48 shows.
Because no overhead crane is available at every machine
EAS designed this electric driven car to lift and lower moulds
up to 2 t over and in the injection moulding machine. The vertical lifting stroke is 3000 mm and the horizontal stroke
is 1500 mm.
Ask EAS for your applications.
For a range of vertical mould carriers, producing different internal part for a
well-known car manufacturer in Germany, the space in front of the mould carrier
was very limited. A special designed electric driven car on rails was developed
to overcome these difficulties.
The car can carry two moulds of each 20 t and the upper bed can turn
180 degrees. The mould sequence is therefor as follows; the car arrives with
the new mould on the car, it docks on at the press. The existing mould is pulled
from the machine onto the car, then unlocks and drives back two meters where
the upper bed is turned 180 degrees. The new mould is now brought to and into
the machine with a total mould change time of 10 minutes.
A well-known Italian car manufacturer developed a very special injection
moulding machine to produce car bumpers. The requirements were; faster,
more flexible, reduce labor cost, reduce energy consumption, reduce floor
space and optimize the production process control by automation.
The mould change cars are having the following features;
 two way two direction travel with one guiding rail
 a 65 t load bearing capacity
 A floating upper bed table permitting easy self centering
of the mould with the upper platen
 Compact size
 Control by means of a remote push button station
 A floor installed carriage guiders, mono rails and side tracks with crossing for two way movement
 Change over time for 1 mould in less then 10 minutes
EAS developed together with Krauss Maffei in Germany a very fast moving
mould transport table. Due to the manufacturing method the 6 t mould needed
to be moved over a distance of 3000 mm in less then 5 seconds. This short
timeframe is including acceleration and deceleration of the heavy mould and
mould bed. EAS found the solution with the help of air cushions, normally used
on our aircushion mould change cars, but now used to float the mould bed and
the mould over the smooth and flat table frame.
Pre-heating stations
Save hours on your expensive production machines
In addition to the use of time saving automatic
clamping and multi coupler systems, pre-heating
moulds outside the machine can drastically
reduce mould change over down time. Once
clamped in position, with the energy circuits
connected, a preheated mould is ready for instant
This pre-heating can be done by a separate pre-heating
station or by integrated pre-heating on the mould change car
or table. Dependant on the degree of automation involved,
such a station can be equipped with manual or automatic multi
couplers and the requisite temperature controllers.
This separate mould pre-heating station is used to preheat 20 to 40 t moulds
out side the press.

with your EAS partner.
simple and safe maintenance
of your expensive tools
A further stage in the automation of your injection
moulding plant is the installation of an inspection
unit. This rationalizes the inspection and servicing
of moulds, superceding a variety of slow and
sometimes hazardous methods involving jacks
and levers or block-and-tackle. Equipped with
hydraulic or magnetic clamping systems on fixed
and movable plates, the inspection unit greatly
facilitates the rotation and precise positioning of
moulds for maintenance and repair work; either as
separate halves or coupled tools.
A German supplier of washing machines uses this inspection
unit with two tilting platerns for 20 t moulds. The loading and
unloading of the moulds is done by an electric driven and air
floating mould change car. The unit can also simulate core
pulling movements and ejector couplers movements.
For a well known German manufacturer of plastic containers
EAS equipped several large injection moulding machines up
to 6000 t with an adaptive hydraulic clamping systems, an air
cushion mould change car, several mould storage racks and
an inspection unit for moulds up to 100 t.
A small unit for moulds of 2 t and with tilting platen.
The control panel can be move around the unit by the operator.
Safety mirrors as well as safety mat are also installed on this unit.
EAS supplies these units in several sizes up to 200 t mould
weight. The units can be equipped with hydraulic cylinders to
tilt one or two mounting plates 90 degrees.
For safety reasons the units can be equipped with a safety mat,
which stops all movements if somebody steps into the table
and or with safety light curtains which also stops any movement
if somebody comes too close to the unit.
The unit can be equipped with a number of options;
 Additional hydraulic or magnetic clamping systems for automatic vertical or horizontal mould loading.
 U-shape backplates in order to be freely accessible from the back.
 Multi coupler systems, manually or automatically for preheating purposes and or for controlling and checking the core pull cylinders.
 Movable upper clamping systems for different sizes of backplates.
 Ejector coupler with ejector cylinder for simulation of ejector movements.
 Steps and stairs for better excess.
 Connection for machine control to simulate certain programs.
 Spotting capability up to 20 t.
For large container production
heavy moulds up to 110 t are
being transported by an
air-floating car from the storage
into this inspection unit.
Either the mould half or the total
mould can be turned on one side
of the unit. The back of the plate
is open, allowing maintenance
and inspection at the back of the
mould. Hydraulic core pulling cylinders are actuated in sequence with the opening
stroke. Easy and safe maintenance without a huge overhead crane enables this
customer to deal with transport and maintenance of very large moulds, fast and
Mould turning units
Combination of a mould change car and an inspection unit
A special electrically driven mould change car
for moulds up to 1700 kg is also used as an
inspection unit.
The car has also height adjustment from 950 mm towards
1300 mm and has an electric push/pull device to change
moulds on vertical press. The platen on the car is also equipped
with spring loaded mould lifters from the EAS QDC program.
Away from the press the mould halves can be separated over a distance of 600 mm and each platen can be turned 90 degrees for maintenance.

EAS can also supply mould turning or mould manipulators to turn your
expensive moulds 90 degrees for transport or storage in a different way.
This turning unit is for moulds up to 20 t and is remote controlled. EAS can supply
these units up to 100 t mould weight.
Rack storage and lift systems for moulds or dies
EAS offer a wide range of mould and
die storage systems. These can be
simple roller beds for horizontal
mould or die storage systems or
automated tool storage systems for
100 to 200 moulds or dies with
several layers. They can be manually
operated or fully automated.

and in many cases
this is away from the machines
These horizontal mould storage systems are loaded and un­­­­­loaded by means of electric driven mould change cars, on which
either manual or automatically moulds are placed. Underneath
the moulds is room for other mould related equipment.
This electric driven mould change car for a large vertical press can bring the
moulds far away from the press to a special mould storage area.
The moulds can be stored left and right of the electric driven car.
The driver has a camera and a monitor for exact positioning the car
into the press. Changing and store moulds between 10 and 20 t is in this way
simple, fast and safe.
