About Rudolf Schwarz
Rudolf Schwarz GmbH & Co. KG is a manufacturing company specializing in rubber and plastic solutions, headquartered in Siegelsbach in the district of Heilbronn. Since 1965, the company has produced rubber molded parts from elastomers and thermoplastic elastomers (TPE), rubber-to-metal bonds and rubber-plastic parts as 2K components. The product portfolio includes gaskets of all kinds — including flange, frame, manhole and DIN gaskets, inflatable seals, hose rings, round and profile lip rings and collars — as well as rubber-coated sprockets, compensators, chain tensioners, fan flaps and gaskets for gearbox and engine sealing. In addition to series production, the company offers analysis and consulting, material selection, calculation, prototype and tool making as well as assembly and delivery. In-house development led to a patent for a spur gear with backlash compensation. Customers come from the automotive, aerospace, water technology, mechanical engineering, medical technology, vehicle construction and technical trade sectors. The company is part of the MAX WERTH GROUP and is certified according to IATF 16949:2016 and ISO 9001:2015.
