More about our production

Heat and surface treatments

At the customer's request, you can obtain all turned parts from us with a heat and / or surface treatment. We work with selected partners and suppliers and can offer treatments such as hardening, annealing, nickel-plating, silver-plating, gold-plating, anodizing and the like.


After machining, the turned parts are given the appropriate finishing treatment if required. Unwanted burrs that arise on the work pieces during the manufacturing process are removed in-house using various methods such as blasting, barrel finishing or manual fine deburring. The parts are then gently cleaned and degreased in a cleaning system down to the smallest hole.

Quality assurance

The entire production process is monitored by means of SPC (Statistical Process Control) and thus ensures high product quality right from the start. In addition, if required, we use flexible testing machines and offer 100% testing for defined features.


With us you can be sure that the goods will arrive undamaged and on time. Depending on customer requirements, we deliver the goods as bulk goods in bags or in appropriate plastic containers. You can also purchase products with higher quality requirements from us individually set in plastic trays. We can supply customers from Grenchen and the surrounding area quickly and directly on request.
