Frequently asked questions

How do I choose the right solution for my application?

Contact our engineering department – we will help you select product type, material and finish for your specific use case. Backed by 50 years of experience.

How can I optimise the manufacturing cost?

We optimise the design for serial production (material choice, geometric parameters, finishing technology). Often we cut cost by 15-30% without losing functional parameters.

How do I move from prototype to serial production?

We make prototypes in 24-72 h. After prototype approval we roll out the series in 2-3 weeks with full quality control and batch traceability.

How can we shorten lead time without losing quality?

We have our own CNC machine park, toolroom and quality control lab. Everything under one roof shortens response time to design changes.
