About Kläger SPC
Kläger SPC GmbH & Co. KG, based in Hartha (Saxony), has been manufacturing technical precision parts and hybrid components from thermoplastic plastics since 1992, with a focus on the high-performance plastic PPS. The focus is on precision and hybrid injection molding (insert technology), in which delicate metal inserts such as connectors, contacts, axles or threaded inserts are precisely overmolded. In addition to PPS, PEEK, PEKK, PPA, PA66 GF 50+, PEI, LCP, PA, POM, PP and HDPE are processed on around 70 injection molding machines with clamping forces of 25 to 250 tonnes. The complete process chain – engineering and 3D CAD design, prototyping, in-house tool and mold making, series production, assembly with automation and quality assurance – is located at the Hartha site. More than 60 million plastic parts are produced annually from over 700 tonnes of granulate. Customers include the automotive and electrical industries, the consumer sector and industries such as defense, semiconductor manufacturing, heat pump and hydrogen technology.
