Plastic injection moulding of technical precision parts

We offer high-performance moulds for large-volume production and low-cost moulds for small-volume production tailor-made for your injection moulded part. We are capable of producing injection-moulded parts with a unit weight of 2 g to 500 g using a clamping force of up to 100 t. Our injection moulding machines and long-standing relationships with plastic suppliers allow us to determine the optimal production parameters. As a result, the parts can be reproduced exactly at any time.

Alongside the material used, the injection mould is the crucial factor in a high-quality plastic part. Experience and an in-depth knowledge of injection moulding are prerequisites for the design of both the mould and the moulded part. With our in-house tool shop, modern production technology and our experienced, qualified employees, we can achieve the quality, cost-effectiveness and speed required to put your product on the road to complete success.

Our absolute adherence to operational plans and to inspection and work instructions at every stage of production guarantees a high level of reliability. In turn, this ensures that our customers’ quality and scheduling requirements are met. Each process step is precisely defined, recorded and evaluated in minute detail through self-monitoring, which includes SPC data acquisition. This means that we are able to respond immediately to dimensional changes and thus ensure constant process reliability.
