Subassembly production

Precisely. Accurate. Certified.

We don't just form a unit as a company

In subassembly production it is about adding the perfection of assembly to the perfection of the individual parts. We created all the prerequisites for high-quality assembly many years ago and improved them again and again.

Assembly of complex assemblies

Whether apparently simple consumer products such as socket strips with integrated child safety devices or sophisticated handles for minimally invasive surgical instruments: What comes from Frech works, lasts and is fun. You anyway. But above all your customers. And that’s what matters most.
