GEHR GmbH is a family-owned company in its 3rd and 4th generation headquartered in Mannheim and is one of the manufacturers of thermoplastic semi-finished products. Using the extrusion process, the company with more than 250 employees produces a range of solid and hollow rods, sheets, tubes, profiles and filaments made from standard, engineering and high-performance materials such as POM, PEEK, PVDF, PVC, PA, PE, PC, PP, PPSU, PSU and PEI. Semi-finished products manufactured according to DIN EN 15860 serve the machining industry as starting material for finished parts with tight tolerances. The portfolio comprises the product lines MEDI-GEHR (medical technology, ISO 10993, USP Class VI), ECO-GEHR (materials made from renewable raw materials) and FIL-A-GEHR (filaments for 3D printing). In addition to stock production, GEHR offers custom manufacturing with more than 30 materials and over 600 colors, post-processing (cut-to-size, planing/milling, grinding, laser and inkjet marking), ultrasonic testing for defects, cleanroom production Class 7 as well as plastics training. Semi-finished products and proximity to customers are ensured through production sites in Mannheim, Boothwyn (USA) and Toronto (Canada) as well as sales offices in Europe, Asia and Latin America.
