Willi Haller

What Willi Haller does

Willi Haller GmbH is a family-owned German plastics processor and toolmaker headquartered in Lahr, Baden-Württemberg, operating continuously since its founding by Willi Haller in 1970. The company designs, builds, and operates injection molds and produces technically high-quality injection molded plastic parts for industrial customers in four named verticals: electronics and electrical, automotive, household goods, and hotel/cosmetics. Its operations are vertically integrated across four in-house functions — Konstruktion (CAD-based design), Werkzeugbau (tool construction), Spritzerei (injection molding), and Montage (assembly) — supported by two VISI-equipped CAD workstations, a press park of 29 injection molding machines with clamping forces from 150KN to 3000KN, and capabilities spanning 1K and 2K (two-component) molding with insert technology and multi-cavity tooling up to 32-fold cavities.

The business processes a broad thermoplastics range including commodity plastics (PET, PC, ABS, PS, PP, POM, PPO, PMMA, PA, PE) and engineering plastics (PES, PSU, PEI, PPS, PEEK, PBT), and provides finishing services such as ultrasonic welding, leak testing, pad printing, sub-assembly, and outsourced coating, painting, hot stamping, and screen printing. The revenue model is B2B project/quote-based custom manufacturing of parts and molds, with go-to-market executed through direct enterprise sales to manufacturers and system suppliers — primarily in Germany, with no disclosed geographic expansion beyond a single production site in Lahr. The firm is led by Managing Director Axel Düran following the recent succession from Birgit Düran, and continues family-controlled ownership with no disclosed external equity, debt financing, M&A, or subsidiary structure.
