About Seifert Kunststoff

Seifert Kunststoff GmbH, based in Neu-Ulm, specializes in CNC machining of thermoplastics. Precision components are produced to drawing or CAD data on modern 3- to 5-axis machining centers as well as CNC turning centers with driven tools, Y-axis and sub-spindle – from single parts and prototypes to series production, including large-volume series with bar feeders. The range extends from standard materials such as PVC, PE and PP to technical high-performance plastics such as PEEK, PTFE, PVDF, PPS and PPSU; PVC parts can also be bonded and welded. Typical products include housings, guide and sliding elements, insulation and spacer components, shafts, bushings, valve seats and fittings. Customers include companies from mechanical and plant engineering, water and process technology, medical technology, semiconductor and microelectronics, as well as food processing and packaging. The company is certified to DIN EN ISO 9001:2015 and manufactures with documented measurement and inspection reports.
