Magnetfabrik Bonn

What Magnetfabrik Bonn does

Magnetfabrik Bonn GmbH is a privately held, family-owned German Mittelstand manufacturer of permanent magnets and custom magnet systems, founded in Bonn in 1935 and operating from a single headquarters and production site at Dorotheenstraße 215, Bonn. The company produces polymer-bonded, sintered, and cast magnets across multiple material families — including polymer-bonded hard ferrite (Sprox®), polymer-bonded NdFeB (Neofer® p), polymer-bonded SmFeN (Neoperm p®), AlNiCo, and rare-earth-cobalt (Seco®) — using injection molding, compression molding, and sintering. Proprietary process capabilities include multi-pole magnetization, multicomponent injection molding, and Halbach array assembly, supported by in-house tooling, automation, R&D, and quality management.

The business model is built on three revenue streams: sale of branded magnet materials and stock magnets, custom-engineered magnet systems and assemblies, and engineering/R&D services. Pricing is quote-based and not publicly disclosed, reflecting the application-specific, co-engineered nature of the work. Go-to-market combines a direct Bonn-based field-sales force covering core German industrial regions with a network of seven named industrial agencies and representatives spanning the rest of Germany, Austria/Central Europe, Switzerland, Eastern Canada, UK/Ireland, and India; brand-building channels include trade fairs (Formnext, Coiltech, Electronica) and a technical knowledge base (Magnet ABC, Magnet Calculator, Magnetization Modes, Magnet Technology Compact publications).

The customer base is heavily weighted toward automotive tier-1 suppliers (Bosch, ZF, Continental, Kiekert, Magneti Marelli, Mitsuba, Swoboda, Hengst, Holmco) with secondary exposure to medical technology (Dräger), industrial automation (Festo), and filtration (IBS Filtran). The company holds IATF 16949:2016, ISO 9001:2015, and ISO 14001:2015 certifications, alongside REACH Art. 33 compliance. As of September 1, 2025, leadership transitioned to a new Managing Director (Mischa Thönnes) under a "Mission AEM — Agile, Efficient, Market-oriented" operating program, with the prior Managing Director (Dr. Martin Grönefeld) continuing in Strategic Business Development.

Core offering

Magnetfabrik Bonn manufactures and supplies permanent magnets and complete magnet systems in polymer-bonded, pressed, cast, and sintered forms across material families including NdFeB (Neofer® p), SmFeN (Neoperm p®), SmCo (Seco®/Seco p®), AlNiCo, and hard ferrite (Sprox®). The company sells both standard catalog stock magnets and custom-engineered application-specific solutions, producing complex geometries via injection molding, extrusion, rolling, and compression molding with precise multi-pole magnetization. Custom magnet systems combine magnets with conductive elements and mechanical components for automotive, medical technology, and industrial automation customers.

Product overview

Magnetfabrik Bonn is a manufacturer of permanent magnets and magnet systems, offering a comprehensive portfolio of material types including polymer-bonded magnets (Neofer® p/Neoperm p® for NdFeB/SmFeN, Sprox® for hard ferrite), sintered/cast rare earth magnets (Seco® for SmCo, Neofer® for NdFeB), and AlNiCo magnets. The company provides both standard stock magnets and custom-designed solutions across forming technologies including injection molding, pressing, and sintering. Their product range is complemented by engineering services covering research & development, tooling & automation, production, and quality management. The portfolio includes branded materials (Neofer®, Neoperm p®, Sprox®, Seco®, Seco p®, Prac®, Sprac®) alongside commodity material types.
