Metallwarenfabrik Gemmingen

What Metallwarenfabrik Gemmingen does

Metallwarenfabrik Gemmingen GmbH is a privately held German industrial manufacturer founded in 1961 and headquartered in Gemmingen, Germany, operating two production facilities — one in Gemmingen and one in Hungary — with approximately 300 employees across the group. The company runs two integrated business pillars: a core stamping and die-casting technology business that produces precision aluminum die-cast motor components and electrical sheets for industrial OEMs, and a power generator business sold under the registered GEKO and EISEMANN brands to commercial, consumer, and emergency-services buyers. Its product catalog exceeds 300 SKUs, and its customer base spans industrial/geared motor manufacturers, fan/blower/compressor/pump OEMs, medical and wind-energy equipment makers, roller shutter and gate drive OEMs, and DIN 14685-compliant emergency-services agencies.

The underlying manufacturing technology is built around vacuum-assisted aluminum die-casting (unit weights 0.1–6.0 kg) and high-speed precision stamping of electrical sheets up to 280 mm in diameter, supported by 17 die-casting machines with 300–900 t clamping force and four high-speed stamping presses with 110–250 t punching capacity. Proprietary know-how includes the tear-off (Abreiß) casting process for low-imbalance rotors in IEC sizes 56–112 and an in-house design office with rapid prototyping, investment casting prototypes, laser-cut stamped parts, and integrated toolmaking, enabling prototype-to-series single-source delivery. Quality assurance is ISO 9001:2015 (TÜV Rheinland / TÜV AUSTRIA) and ISO 14001 (SGS/Hungary) certified, with 3D measurement inspection on critical components.

The business model is B2B hardware sales plus a branded power generator channel: pricing is quote-based and per-customer (no public price list), GTM is direct enterprise field sales supported by phone hotline, dedicated email channels, specialist advisors, downloadable brochures in German and English, and event-driven lead generation through Coiltech Germany and Coiltech Italia 2024. Distribution combines direct sales, a corporate product website, a dedicated GEKO/EISEMANN brand microsite, the Hungarian subsidiary's femmuvek.hu storefront, and a 35-business-partner network, with omnichannel social presence on Facebook, YouTube, LinkedIn and X. Revenue streams are (i) series production of stamped and die-cast components, (ii) GEKO and EISEMANN generator systems, and (iii) custom engineering, prototyping and contract manufacturing services.

Core offering

Metallwarenfabrik Gemmingen GmbH produces customized aluminum die-cast parts (unit weights 0.1–6.0 kg) and precision electrical sheets/stamping packages (up to 280 mm diameter) for electric motor manufacturers in IEC sizes 56–112. The company also manufactures and sells branded power generator systems under the GEKO and EISEMANN names for industrial, commercial, and emergency-services end users across two production sites in Germany and Hungary.

Product overview

Metallwarenfabrik Gemmingen GmbH operates as a single industrial manufacturer with two integrated business pillars: a core Stamping and Die-Casting Technology service line (producing stators, rotors, motor housings, end shields, and terminal boxes in IEC sizes 56–112) and the dual sub-brands GEKO Power Generator Systems and EISEMANN Power Generator Systems (DIN-compliant generators for emergency, BOS, and commercial use). The two pillars are delivered from a shared manufacturing footprint across two factories in Germany and Hungary, with the GEKO/EISEMANN generator portfolio running alongside the stamping and die-casting components business under one unified quality and engineering organization.
