Quality is when the customer, and not the product, comes back!
The keen eyes of our production and quality assurance employees, the latest measurement techniques and regular internal and external audits guarantee adherence to our customers’ strict quality demands.

To perform our services reliably we don’t just use high-quality technology, such as a multi-sensor coordinate measurement device and the latest CAQ software for control and evaluation; we especially prize our employees’ many years of experience in production self-monitoring and quality assurance.

From raw materials intake, production and assembly to delivery of the goods, all business processes are documented, tested and regularly audited for potential improvements.

Our company is DIN EN ISO 9001:2008 and EN 9100:2018 certified.

We maintain an active and open dialogue with our business partners and take on constructive criticism from them.

We monitor all of our processes. We are constantly measuring, checking and testing.

We promote continuous improvement through ongoing education and optimisation of current processes.
