Biesinger

What Biesinger does

Biesinger GmbH is a family-owned German precision manufacturing services provider headquartered in Haigerloch-Hart, Baden-Württemberg, founded in 1986 as a wire-erosion job shop by Gregor Biesinger and now jointly run by his sons Ingo Biesinger (Commercial Director) and Jörg Biesinger (Technical Director). The company employs 11-50 staff (26 as of 2015, plus 5 inherited from the February 2024 acquisition of Nagolder Erodiertechnik) and operates a second site in Nagold acquired in 2024. It brands itself as the "Unikat-Fabrik," reflecting that roughly 95% of its production consists of unique, one-off parts rather than serial production.

Its core technology stack is built around wire EDM (Drahterodieren), sinker EDM (Senkerodieren), 5-axis simultaneous HSC milling on Hermle machining centers, and CNC turning, supplemented by automated handling systems that enable unmanned 24/7 operation. Programs are generated in hyperMill CAD/CAM; quality is verified on Zeiss coordinate measuring machines with 3D measurement protocols, and the company holds DIN EN ISO 9001 certification continuously since 2001 (renewed May 2025). Adjacent in-house products include custom electrodes (copper and graphite), handling/gripper systems, rapid tooling for pre-series injection molding, metal injection molding (MIM, with external debinding/sintering partners), fixtures and full tool construction. Differentiating technical capabilities include 0.05 mm wire diameters, microfinish to Ra=0.2, 430 mm cutting height, hard milling up to 70 HRC, and start-hole EDM from Ø0.3-3.0 mm.

Biesinger's revenue model is B2B contract manufacturing sold directly to industrial customers via phone, email and website inquiry, with project-based quote-based pricing and no public rate cards. The go-to-market is sales-led, targeting the DACH region across verticals including automotive (with Porsche cited as an example customer), aerospace, medical technology, watchmaking, electrical engineering, mechanical engineering and furniture/rubber tooling (zitzengummis). Marketing channels span a corporate website, LinkedIn, Instagram, Facebook and YouTube, plus active VDWF association membership and trade show presence (Fakuma, Moulding Expo). The company has no external investors, no disclosed revenue, and operates as a privately held GmbH registered in Stuttgart.

Core offering

Biesinger GmbH provides precision manufacturing services and built-to-print components, including wire EDM and sinker EDM machining, 5-axis HSC milling, CNC turning, and full toolmaking. The company also manufactures electrodes, handling systems, rapid tooling, metal-injection-molded parts, custom fixtures, and specialized tools for industrial clients. Output targets tight-tolerance, complex-geometry applications.

Product overview

Biesinger GmbH operates as a precision manufacturing services company offering a unified suite of metalworking services centered on EDM (wire and sinker erosion), 5-axis HSC milling, and CNC turning. The product portfolio includes four core machining services (wire EDM, sinker EDM, milling, turning), complemented by an in-house electrode manufacturing capability for EDM operations. The company also provides specialized products including custom handling/gripper systems, rapid tooling for pre-series injection molding, metal injection molding (MIM), custom fixtures and jigs, and comprehensive tool construction services. The offering is architecturally integrated: electrode production supports the EDM services, while the tooling and rapid tooling capabilities feed into injection molding and small-batch production, creating a one-stop precision manufacturing solution for prototypes, individual parts, and small series in the DACH region.
