About Horst Fischer GmbH
Horst Fischer GmbH is a plastics processor based in Gundelfingen near Freiburg im Breisgau with more than 60 years of experience in plastics processing. The company manufactures systems and special systems for solar and semiconductor technology, wastewater treatment, acid supply and disposal, and exhaust air technology, including ultrapure water and DI water systems, dosing stations, collection tanks and wastewater treatment plants. In addition to plant engineering, the portfolio includes the processing of Plexiglas (PMMA) and Makrolon (PC) through cutting, polishing and bonding, the production of standard and special pipe fittings, tank construction as well as customer-specific components and custom-made products. Thermoplastics such as PE, PP, PVC, PVDF, PTFE and PPS are processed, supplemented by copper and stainless steel (VA) for piping. CNC-milled and turned parts complete the manufacturing range. Customer industries include electroplating, swimming pool construction, drinking water supply, landfills and laboratory technology.
