Rauschert

What Rauschert does

Rauschert (legal entity Paul Rauschert GmbH & Co. KG) is a family-owned German manufacturer of technical ceramics, plastic injection-molded parts, and ignition/heating systems, headquartered in Pressig/Schesslitz, Bavaria, and operating more than 20 manufacturing and sales locations across Europe, the Americas, and Asia. Founded in 1898 as a producer of electroporcelain, the company today runs five core product areas: engineering ceramics (oxide ceramics such as RAPOX® and RAPAL® aluminum oxide, zirconium oxide, plus steatite, cordierite, and porcelain), plastic moulded parts in high-performance thermoplastics (PEEK, PFA, PVDF, ETFE, E-CTFE), ignition systems and high-temperature ceramic heating elements (including the patented HTH lamellar heater operating up to 1100°C continuous / 1300°C brief), ceramic nanofiltration membranes under the inopor® brand, and a custom engineering division for special machinery, tooling, and automation. Approximately 1,200 employees serve industrial OEM customers across mechanical and chemical plant engineering, electrical engineering, medical technology, textile machinery, food/beverage/pharma, and aerospace, with named enterprise accounts including Miele, Bosch, Siemens, ZF, BASF, Evonik, DOW, Akzo Nobel, Covestro, and the European Space Agency.

The business model is direct B2B sales with quote-based, custom pricing for engineered components and systems, supported by ISO 9001, 14001, and 50001 certifications. Multi-year contracts dominate (e.g., supply of high-temperature heaters to the ESA ExoMars program, ongoing ceramic tower packing supply to BASF/Evonik/DOW, and textile ceramic components to Chinese textile machinery majors Barmag Suzhou, Saurer China, Tongkun, Shenghong, Rongsheng, and Hengli). Rauschert pursues R&D through proprietary programs and participation in at least eleven EU- and German-funded consortia spanning gas separation membranes, hydrogen production, hospital wastewater treatment, dairy filtration, and helium recovery.

Revenue is not publicly disclosed. With roughly 1,200 employees across 20+ global sites, an executive managing director team drawn from the owning family (Roland P. Rauschert, Dr. Richard Metzler) alongside non-family MDs (Theo te Baay, Roland Neubauer), and an active expansion cadence (Rauschert Norden AB in Sweden, August 2023; Rauschert Ameal second Portuguese site, February 2024), Rauschert positions itself as a vertically integrated, owner-managed specialty ceramics platform serving safety-critical and high-temperature industrial applications rather than a high-velocity venture-style growth story.
