About ElringKlinger Kunststofftechnik
ElringKlinger Kunststofftechnik GmbH, headquartered in Bietigheim-Bissingen, is a globally active technology partner for high-performance plastics. The company develops and manufactures seals, bellows, plain bearings, wear rings, diaphragms, hoses and profiles, piston rings, semi-finished products, custom assemblies and plastic heat exchangers for customers in industries such as automotive, mechanical engineering, chemical and process engineering, energy, the semiconductor industry, life sciences/medical technology, and oil & gas. The value chain begins with in-house material development and compounding using the Polytetraflon® PTFE, Moldflon® fluorothermoplastic and fluorine-free Elringplast material families (including PEEK, PPS, PPSU, PE-UHMW, PVDF). Manufacturing covers PTFE sintering and pressing, injection moulding and extrusion of fluoropolymers, machining by turning and milling to drawing from single parts to large-scale series, plastic welding processes as well as assembly – also under cleanroom conditions (ISO Class 8). Design and component optimisation are supported by FEM simulation (FEA). More than 750 employees at five sites on three continents generated revenue of €144.5 million in 2025. The company is part of the ElringKlinger Group.
