External processing
We carry out the major part of the value creation activities in-house. For the few processes we do not perform at our facilities, we collaborate with selected partners. They are outstanding specialists in their areas, and quality is as important to them as it is to PROTEC. These longstanding and trustful partnerships are an important pillar of our company.
Examples of processes carried out by external partners:
- Heat treatment
- Surface treatment
- Thermal deburring
