Complex handling of injection molded parts in a clean room environment
For Flex Precision Plastic Solutions, we automated the complex handling of medical injection molded parts in a clean room. A downstream inspection station checks the sophisticated plastic parts using a modern vision system.
The challenge
Flex Precision Plastics Solutions is part of the global Flex Group, which has 250,000 employees at over 300 locations around the world. At the Hägglingen AG site, medical technology parts of the highest quality are manufactured under clean room conditions. The challenge was that delicate injection molded parts had to be removed, inspected and stacked and packaged aseptically - in very tight space conditionsand in 3-shift operation.
The solution
Injection mold partextraction - whether with or without inserts - are predestined for automation with industrial robots. For Flex Precision Solutions, we developed a robot that is located next to the injection mold and removes the parts individually or multiple times from a complex plastic injection mold. A gripper turns the parts, separates them from the sprue and places them neatly in the downstream inspection stations.
Finally, the parts are stored in packaging trays in a dimensionally stable and protected manner. The test stations can be equipped with different measuring systems and check the parts for surface quality (via a vision system), or leaks (with a high voltage process). The entire system meets the clean room requirements and is documented and certified in accordance with GMP.
“We were impressed by the ability to cover many process steps with one system. And this under the most demanding cleanroom conditions and in confined spaces.”
The project
All system assemblies were developed and built by Robotec Solutions. This enables us to offer our customers a coherent solution and guarantee at least 20 years of support and spare parts availability.
