Quality Assurance

Systematically focused on quality.

Quality is of utmost importance in our day-to-day work. We train and manage our employees with the aim of putting the skills we have developed to use to ensure consistently high quality. We pursue active quality management at all corporate levels and in all corporate processes.


We optimise our processes on an ongoing basis and guarantee compliance with international and industrial standards by means of external monitoring and certification.

The Swiss Association for Quality and Management Systems (SQS) is responsible for monitoring and certification.

As part of our quality management system, all measuring and test equipment is monitored and calibrated on an ongoing basis.

Non-destructive testing (e.g. surface roughness, PT and X-ray testing) is performed by our own specially trained and certified personnel, or by accredited test institutes.

We provide test documentation or test reports for our deliveries on request.
