What Hack Formenbau does

Hack Formenbau GmbH is a third-generation, family-owned German manufacturer of high-precision injection molds, headquartered in Kirchheim unter Teck near Stuttgart, with a secondary manufacturing site at Wielandstraße 24 in the same city. Founded in 1950, the company serves an international customer base across seven regulated end-markets — medical, pharmaceutical, optical, healthcare & consumer, packaging, dental, and industrial/technical — producing single- and multi-component molds, multi-cavity systems, and complex special tooling under its proprietary HACK® Mold Technologies brand, which includes the patented HACK® varioturncube as well as cube, stack, varioturnstack, variotwinstack, index-plate, lift & strip, unscrew, in-mold-labeling, in-mold-closing, and rotary-table architectures. A 25-year-old in-house Technical Center performs rheological simulation and full validation of molds and production systems on partner equipment under real conditions, and is treated as a core competitive asset by the company.

The business model is primarily project-based and quote-driven: revenue comes from one-time engineering and build contracts for custom molds, supplemented by professional services (consulting, maintenance, optimization, 24/7 support) and, more recently, a subscription/recurring digital revenue stream from moldlife® sense, an IoT monitoring platform for installed molds. Go-to-market is direct enterprise field-sales with dedicated contact persons, reinforced by regular booth presence at the major international plastics and MedTech trade shows (Pharmapack Paris, MD&M West Anaheim, K Show Düsseldorf, NPE Orlando), a corporate website with contact forms, and organic social channels (LinkedIn, Facebook, YouTube, XING). The company also maintains a talent pipeline via a dual-study cooperation with DHBW Stuttgart, supporting its stated headcount of over 200 qualified employees. Ownership is concentrated within the Hack family, with Gunnar Hack serving as authorized managing director (Geschäftsführer); no institutional investor or parent-company involvement is indicated.
