What Sonnplast Solutions does

Sonnplast Solutions GmbH is a privately held German manufacturer of high-precision technical injection-molded thermoplastic components, founded in 1989 and headquartered in Sonneberg, Thuringia. The company operates 45 injection molding machines with clamping forces from 50t to 1500t across three-shift production, processed by roughly 180 employees. Its core business is supplying complex single- and multi-component plastic parts to automotive OEMs and Tier 1 suppliers, including seat trims, ISOFIX covers, B-pillar covers, headlamp housings, air intakes, and climate control function parts for customers such as BMW, Volkswagen, Lear, Adient, Mubea, Plastic Omnium, AMK, and REHAU.

The company's technology stack includes 2K/3K multi-component injection molding, gas internal pressure molding, metal overmolding, and fabric back-injection, complemented by in-house tool design and manufacturing with Mold Flow simulation, an in-house metrology laboratory using Zeiss and Mitutoyo equipment with PolyWorks surface comparison, and a secondary processing portfolio (laser cutting, ultrasonic welding, stamping, hot stamping, printing, assembly). Quality systems are certified to IATF 16949, ISO 9001:2015, and TISAX, with ISO 14001 and ISO 50001 planned for 2024. Active R&D partnerships with Audi and an unnamed Munich-based OEM focus on automotive part reuse and wood-plastic composites, while the non-automotive segment supplies roughly 200 SKUs to German retailers including Edeka, Kaufland, Lidl, Netto, Tegut, and Marktkauf.

Sonnplast generates revenue through three streams: (1) recurring production of custom injection-molded components under tooling agreements, (2) sale of customer-financed injection molds following 6-12 months of pre-financing, and (3) secondary processing services. Distribution is direct B2B, primarily via Just-in-Time and Just-in-Sequence delivery to customer workstations, supported by specialized logistics partners. The business is managed by Geschäftsführer Axel Berke with Technical Director Uwe Langenberg, and there is no disclosed institutional, PE, or parent-company ownership.
