About the WOLL.GROUP
The WOLL.GROUP comprises the companies WOLL Maschinenbau GmbH (Saarbrücken), RITZ Maschinenbau GmbH (Östringen) and M-O-T Mikro- und Oberflächentechnik GmbH. Having emerged from a small metalworking shop over 60 years ago, the company today develops and manufactures special machinery, automated assembly and production systems as well as process and process engineering for filtration, film and bag processing and the semiconductor sector. In its own manufacturing (WOLL.Manufacturing), parts are produced from single pieces up to large series and frame orders: sheet metal and tube/profile processing (laser cutting, folding, tube laser), CNC milling including 5-axis, CNC turning, surface grinding, welding (MIG/MAG, TIG, plasma, laser) as well as assembly of modules. Materials include steel, stainless steel, aluminium, brass, copper and special alloys. Customer industries are medical technology/life science, automotive, the semiconductor industry, industry, energy storage/e-mobility and water treatment/filtration.
