The company's product offering centers on the design, manufacture, and inspection of sophisticated injection molds for the automotive/mobility, medical, and electrical engineering industries, operating at pressures exceeding 1000 bar on state-of-the-art equipment. All major production steps — design, manufacturing, and inspection — are performed in-house, and tools are validated in the company's proprietary technical center (Technikum) using its own injection molding machines, with initial sample test reports (Erstmusterprüfberichte) and documentation provided upon handover. Customers are unnamed major manufacturers described as the "who's who" of their respective industries, served both in Germany and worldwide.

Müller Formenbau generates revenue through project-based, bespoke tooling contracts, with pricing dependent on complexity, specifications, and volume. Its go-to-market is consultative and relationship-driven, emphasizing close customer dialogue from project initiation through series production and pilot runs (Nullserie). The company also offers supporting services including consultation, development, and comprehensive documentation as part of its delivery scope. Distribution is exclusively direct-to-enterprise, with no indirect channels or resellers apparent. The company emphasizes its "Mitdenken" (thinking along) philosophy, regional Mittelstand identity in the Swabian Alb, and continuous in-house apprenticeship training as core elements of its value proposition.
