Beier

What Beier does

Paul Beier GmbH is a contract precision machining shop (Lohnfertigung) headquartered in Kassel, Germany, founded in 1924 and operating from a single production facility at Naumburger Straße 36. The firm converts customer-supplied drawings into high-precision metal components across single-piece manufacture, small-series production, and full machine/assembly builds, using a machine park that spans 5-axis CNC milling centres, turning-milling automatics, CNC lathes, wire EDM, and flat/round grinding on parts up to 3 metres. A distinguishing capability is the machining of difficult materials — zirconium, titanium, molybdenum, nickel-based alloys, and high-strength cast/forged steels — supported by certified welding (DIN EN ISO 3834-2, DIN EN 15085-2), in-house and partner-network heat treatment, surface coating, painting, and FEM-supported documentation.

The business is organised into five vertical competence fields: Railway Technology (Bahntechnik) as a Q1-certified supplier to Deutsche Bahn since 1995; Plastics Technology (Kunststofftechnik) supplying screw sets, segmented elements, nozzle plates, perforated plates, and housings for twin-screw extruders used in compounding, granulation, and re-granulation; Mechanical Engineering (Maschinenbau) for custom machines, gearboxes, shafts, pressure vessels, and food/medical components; Defence for high-strength steel components in military utility vehicles; and Apparatus (Apparate) for seamless pressure equipment and pipelines from special materials with TÜV acceptance. The Q1 supplier status, ISO 9001:2015 quality system, and sector-specific welding certifications function as the firm's primary competitive lock-in across regulated end markets.

Revenue is earned exclusively through bespoke per-inquiry quotations — no catalogue pricing — based on material, geometry, tolerances, batch size, and required certifications. Sales are entirely direct B2B via phone, email, website contact form, and a small in-house sales function; LinkedIn and SEO-optimised service pages provide top-of-funnel visibility. Distribution is exclusively domestic Germany, with relationship-based account management across long-tail industrial buyers. Ownership history: private since 1999 under listed GESCO-Group, transitioned in 2021 to EVOCO AG, where it now operates as one of four companies forming the Precision Werks Group (PWG). The company employs approximately 60 people and is led by Managing Director Dipl.-Ing. (FH) Johannes Overhues.
