How it all begann: The foundation

In September 1991 Reinhold Willems and his son-in-law Walter Marienfeld founded the company WIMA Control GmbH in Heiligenhaus in North Rhine-Westphalia. The company name consists of the first letters of the surnames:

At that time, owner and managing director Reinhold Willems could already look back on more than 20 years of experience in the screw and fastener industry and in the screw trade. In 1991 he came up with the idea of entering the field of quality testing, as this topic played an increasingly important role, especially in the automotive industry.
