Injection moulding

Special processes in plastic injection moulding

Our service portfolio is comprehensive and diverse. In addition to standard injection moulding, we can also respond to your individual needs and requirements in various special processes. Take a look at our injection moulding services:

2C injection moulding

Combination of two different polymers in one injection moulding process to save later assembly steps.

Injection moulding in the cleanroom

Highest cleanliness standards and protection from contamination for sensitive applications in medical technology.

Insert injection moulding

An efficient option for reducing the subsequent assembly. Inserts made of metal or other materials are inserted into the mould and permanently bonded to the article during the injection moulding process.


Individual surface treatments such as laser engraving and finishing for optimal product aesthetics and functionality.
