Tolerances, which often did not represent a problem 30 years ago, are unthinkable today due to the increased requirements. Predefined tolerances can usually only be achieved with state-of-the-art CNC-controlled systems.
Furthermore, the continuous control of operating and production processes according to certain quality criteria is indispensable.
In order to always guarantee this we have already been certified in 2001. Currently we are certified according to DIN EN ISO 9001: 2008.
