When it discovered items were missing from shipments to customers, Danfoss Commercial Compressors responded by increasing reliability in its checkweighing operations.
After extensive research, Danfoss chose a turnkey solution that eliminated interpretation errors and enhanced its efficiency. Now, the company is confident every customer receives the items it ordered.
The Danfoss Commercial Compressors division develops and manufactures piston and screw compressors for refrigeration and air conditioning applications.
Based in Reyrieux, France, the division’s head office is also a major production and logistics site.
its compressors. The accessory packaging workshop through its logistics department has recently been outfitted with
METTLER TOLEDO equipment to help resolve an issue of reliability in checking the packaging of the kits.
Danfoss Commercial Compressors optimizes its supply chain to offer reliable products and solutions that closely match the needs and expectations of its customers. To respond proactively to non-conformity issues, Danfoss increased reliability in its checkweighing with new weighing equipment.
After a customer complaint about missing items from the pack of accessories received, the company sought the best possible weighing equipment that could indicate clearly whether the pack was within the required tolerance or not.
Danfoss chose a high precision weighing platform with 6 kg capacity and 0.1 g readability.
The Reyrieux site mainly manufactures kits containing accessories for maintenance and repair that are supplied with
“METTLER TOLEDO suggested we go for a device equipped with a monitor for recording the weights corresponding to
each part number and a colored screen
(red, orange, green indicators) that allows visual distinction between conforming and non-conforming products,” says
Claire Mendes, logistics manager at the
Reyrieux factory. “The product is an
ICS669check turnkey solution, consisting of a terminal that can check instantly and efficiently for any missing items, without a risk of interpretation errors by the operator due to the indicators displayed.”
As part of the turnkey solution, METTLER
TOLEDO provides all the services associated with the products it had supplied: installation, calibration and training.
“We also appreciate the printer that automatically produces a validation ticket if the weight is correct. That’s why we equipped both our order preparation stations with this complete unit,” says
Mendes. “Since outfitting these two stations, we are happy to say that we have had no more complaints about non-conforming orders. What’s more, we have saved time in the order preparation checking cycle.”

Despite 100% Inspection
The manufacturing process for solar cells consists of a multitude of individual steps. A weight check between each step ensures that only good wafers proceed to the next treatment. METTLER TOLEDO has the right products and the expertise to support machine builders in successfully applying weight based quality control for solar cells.
The transformation process from a block casted poly-crystalline silicon ingot to a solar cell consists of several individual steps. It starts with cutting and shaping the ingots into wafers. Then the wafers have to pass through several etching, coating and printing processes until it is a solar cell with the capability to produce electricity. A strict quality control check at the end of each treatment ensures only good wafers proceed to the next production step.
Weight-based quality control
Measuring the weight before and after each production step is a fast and reliable quality check. It allows for detecting deviations in geometry, completeness and density of the wafer before surface treatment starts. Then the weight difference is used for checking results of etching, coating and printing. It requires weigh modules with repeatable precision between 10 mg and 0.1 mg.
One weigh module for all steps
METTLER TOLEDO’s high-precision weigh modules comply with the requirements.
They can reliably detect deviations of less then 1mg in a fraction of a second. The
WMS104C is the most often used weigh module for quality control in siliciumbased solar cell production. It has a readability of 0.1 mg and the repeatability of
0.2 mg. The software applies filter algorithms to measure correct and repeatable results despite of vibrations from machines and drafts from the air conditioning system. An incorporated calibration weight allows testing of correct function without the need to remove the hosting adapter for the wafer.
The fast interface sends 92 filtered and compensated weight values per second to the control system. The transmitted data can be converted to all common Fieldbus
Systems if required.

40 000 Articles Accurately Picked
When operators pick inventory for hundreds of orders every day, mistakes may occur due to human error. To improve efficiency in terms of both time and accuracy, Teknikprodukter Nordic AB, a Swedish distributor of bearings, power transmissions and seals, implemented a mobile parts counting solution that saves time and money while increasing accuracy.
Logistics Manager Rikard Lundberg says the new solution, which includes an article database and barcode scanner, has eliminated hand counting. In turn, this has reduced time spent on each order – and saved man-power means saved money. The operator brings the BBK462 highprecision counting scale (6 kg x 0.01 g) into the inventory area on a mobile cart, where he or she picks the article.
By scanning the barcode on the package, the scale automatically retrieves the average piece weight from the database.
“Without taking any reference pieces, the operator can immediately start counting the required parts out of the blister,”
Lundberg says. “This process saves a huge amount of time. And with the highprecision scales, we ensure that our customers get the parts they have ordered.” tory is downloaded weekly from the company’s database to the METTLER TOLEDO

Less than 5 Seconds
to Check Shipment Completeness
To be successful, distribution companies must deliver complete shipments on time. By simply checking shipment completeness, they can ensure customer satisfaction and considerably reduce losses. The largest distributor of press in Czech Republic found a simple and effective way to control completeness – by installing a checkweighing scale on its shipping line.
Mediaprint & Kapa Pressegrosso, distributes more than 1 000 titles to outlets throughout the Czech Republic from one state-of-the-art distribution site. The company wants all of its customers to have access to their favorite magazines everyday, everywhere. To ensure completeness of all shipments, Mediaprint chose to checkweigh all its orders prior to distribution. lights. The terminal display shows the operator important information. A single check takes less than 5 seconds to complete.
METTLER TOLEDO integrated three elements into Mediaprint’s existing information system:
“To install a checkpoint, we needed a very precise and robust industrial scale and a solution for comparing the theoretical, computed shipment weight with the actual weight,” says Mediaprint Sales
Director Václav Čihák. He says to do this, the company needed to change its information system. After inspecting a model solution at a customer’s site where scales and systems were in use under rigorous conditions for many years, Mediaprint decided to supplement its exisiting information system with a checkscale from
METTLER TOLEDO, which tailored its solution to Mediaprint’s needs.
Completeness checks in seconds
Mediaprint chose the KB60 weighing platform – with a weighing range of up to 60 kg and 1 g readability as its checkweighing soution. The programmable display unit for the scale, the IND560 terminal, communicates with the parent system via Ethernet. A barcode reader is connected to the terminal and the integrated relay set controls external signal
1. Reference weights of current magazines added to the system
The reference weights are determined using the BBA432-15LA scale designed for piece counting. The scale computes the average weight of one copy on the basis of ten items and communicates the information to the system. The procedure is repeated for all of the publication titles to be distributed that day.
2. System information communicated to the checkweighing scale and comparison result is archived
Depending on the job structure and publication unit weights, the system computes the theoretical weights, including permitted tolerances. The job number is scanned at the checkpoint using the barcode reader, and the system then sends the expected weight to the scale terminal. The result of the theoretical and actual weight comparison is communicated and then archived.
3. Scale checks completeness
The operator places the shipment on the scale. The scale compares the theoretical weight received from the system to the
KB60 high-precision weighing platform (60kg capacity, 1g readability). actual weight to a readability of 1 gram and decides whether the job is complete.
A green signal light indicates the current weight is within the allowed tolerance. A red light indicates that copies are missing or that the shipment includes excess copies. In that case, a manual check is performed. If the job is distributed across a number of packages, then the individual weights in the terminal are added, and the total weight is only compared after the last weighing.
Čihák says METTLER TOLEDO has been supportive throughout the entire system implementation. “As always, when something new is being developed, some details have to be tackled. METTLER
TOLEDO is always willing to provide assistance and quickly solve the problem,“ he says. “The function and reliability of the scale system meet our expectations and we assume it will also be used at our other sites.”
