What WEISS Kunststoffverarbeitung GmbH & Co. KG does

WEISS Kunststoffverarbeitung GmbH & Co. KG is a privately held, family-owned injection molding manufacturer founded in 1946, operating from its headquarters in Illertissen, Bavaria, and a subsidiary (WEISS Hungaria Kft, est. 2007) in Győr, Hungary. The company produces technically sophisticated thermoplastic parts using one- and two-component injection molding processes, serving primarily automotive OEMs and Tier 1/Tier 2 suppliers (passenger vehicles, commercial vehicles, and e-mobility) with safety-critical and functional components including chain tensioning systems, transmission housings (e.g., Porsche Macan PDK via Jopp Automotive), tire pressure sensor housings, and pneumatic level control valves. A secondary non-automotive segment includes pressure cooker valves for WMF/SEB Group, industrial door components for Butzbach (since 2004), and RFID-enabled logistics pallets.

The company's core technical platform is built around vertically integrated capabilities: in-house mold construction (WZ-Formenbau subsidiary, 27 employees, 70 molds annually), proprietary sensor integration into molds for "view into the cavity" inline quality control, automated camera and laser inspection systems, Simcon Cadmould 3D-F process simulation, and 2K injection molding with turning devices for complex assemblies. Total capacity across both facilities comprises 92 injection molding machines (60 in Germany, 32 in Hungary), 33 material drying silos, 18,300 m² of production floor area, and 675,000 individual plastic parts produced daily with 3 million kg annual material throughput.

WEISS operates a project-based B2B sales motion targeting enterprise customers, with dedicated project engineers engaged from concept through series production, just-in-time delivery, and KLT-managed logistics. The firm holds IATF 16949, ISO 9001, and ISO 14001:2015 certifications across both plants. Revenue is not publicly disclosed but press references indicate growth in 2023 and 2024; management transitioned in April 2024, and the company is led by third-generation family member Jürgen Weiss as authorized managing director.
