Our management system under VDA6.1  (DIN EN ISO9001:2000) has been in use for many years and ensures that our products / services are compliant with the highest customer requirements in the automobile / aerospace industry.

In the context of the development of our management, an upgrade to ISO TS 16949 is currently being prepared.
Our internal quality laboratory has all the testing and measuring equipment required to ensure our high production quality.
Naturally, at KOLB, we keep going until “number certain” even at the final inspection stage. Our own optoelectronic testing machines and standard assurances in accordance with various directives ensure that our products leave the company as the customer expects and as our own demands require.
Our staff have a strong sense of responsibility and quality.
