Corporate Group

RITZ Maschinenbau GmbH, based in Östringen, has been a subsidiary of the WOLL Group since 2005. Both companies complement each other and operate hand in hand on assembly automation and process technology projects.

In 2010, M-O-T Mikro- und Oberflächentechnik GmbH, a company for the manufacture of wet chemical process systems for the MEMS and SEMICON sectors, was integrated. As an experienced and committed partner for trade and R&D manufacturers, M-O-T GmbH can look back on a history of more than 25 years in the development and supply of wet chemical processes.


Our group of companies unites 370 highly qualified employees. We bundle extensive know-how in a network around the areas of assembly automation and process technology, welding technology and the manufacture of wet-chemical process systems.

Our expertise has grown over 60 years – our customers benefit from it!
