EXPERIENCE.
PRECISION.
RELIABILITY.

Since 11 October 1982 we have been supplying precision components to the most demanding industries. We invest in a modern machine park, a skilled team and technologies that guarantee repeatability and quality.

We look for partners for whom quality and repeatability of a single part across an entire series are critical. Our team helps optimise production processes and suggests solutions relevant from the product owner's perspective. At the pre-production stage we are not a passive executor of a drawing. Together with the client's designers we select the right machining technology, propose geometry corrections for repeatability and cost, and develop the inspection plan and complete process documentation.
