Driven by precision
With powerful CAD/CAM systems and a modern machine park, we produce demanding components efficiently, reproducibly and economically. As a reliable partner in prototyping, we support you from development through to series production.
Thanks to our comprehensive manufacturing know-how, we support you as early as the development phase and optimise components specifically for manufacturability and cost-effectiveness.
In March 2026 the trade magazine Technische Rundschau described how we work on our 5-axis milling machine from Kern Microtechnik. Read the report at technische-rundschau.ch (in German)
We machine a broad range of materials
- Steels and superalloys Structural steel, high-alloy tool steels, stainless steels and superalloys such as Hastelloy C22.
- Non-ferrous and special materials Aluminium, brass, copper as well as titanium and ceramics.
- Plastics Plastics as well as conductive, heat-resistant and fibre-reinforced materials.
We manufacture components from 0.1 to 1000 mm in batch sizes from 1 to 10,000 pieces – consistently, on time and with reliable process control.
- 0.1 – 1000 mm Component size
- 1 – 10,000 Batch size
