FRÖTEK-Kunststofftechnik GmbH

What FRÖTEK-Kunststofftechnik GmbH does

FRÖTEK-Kunststofftechnik GmbH is a German family-owned plastic technology company founded in 1985 by Bernhard and Barbara Fröhlich in Osterode am Harz. The company operates as a vertically integrated injection molder specializing in battery accessories (Aquamatik watering systems, FRicon flexible connectors, VRLA pressure relief valves, electrolyte level indicators and stirring systems), automotive plastic components, and electrical engineering assemblies. Manufacturing capabilities span precision injection molding with clamping forces from 25 to 1,200 tons, supported by in-house toolmaking, water jet and laser cutting, CNC milling and bending, powder coating, high-voltage testing, and resistance welding across eight production sites in Germany, Hungary, China, and the United States following the December 2025 acquisition of McMinnville Tool & Die (MTD) in Tennessee.

FRÖTEK generates revenue primarily through direct B2B sales of custom and standard plastic components to enterprise customers in the battery industry (lead-acid starter and industrial batteries, Li-ion cells), automotive OEMs (via subsidiaries and partners such as Sweden's Rimaster), electrical engineering, and intralogistics/packaging (through subsidiary Ernst Kraemer & Söhne). Pricing is quote-based with copper-content products subject to monthly stock-market-linked price adjustments, and contracts are typically multi-year. The company holds IATF 16949, ISO 9001, ISO 14001, ISO 50001, and (as of 2025) Volkswagen Group Formel-Q certifications across its production sites. With approximately 700 employees and ~EUR 80 million in FY2023 revenue, FRÖTEK positions itself as a mid-sized one-stop shop for OEM customers seeking complete battery accessory portfolios from a single, locally present supplier.

The company completed a generational leadership transition in June 2023 when long-tenured executive Sascha Brothuhn succeeded the founding Fröhlich family as CEO, with Martin Fröhlich continuing as Group President. Recent strategic activity has centered on expanding into North America via the MTD acquisition, deepening the Li-ion battery safety technology stack through the BMBF-funded VentBatt research consortium, and qualifying for premium automotive OEM supply chains through Formel-Q certification.
