What GERG does

GERG GmbH (legal name: Modell- und Formenbau Blasius GERG GmbH) is a privately-held, family-owned German precision manufacturing and engineering company founded in 1984 and headquartered in Hohenthann, Bavaria. The company operates across six integrated service divisions: Engineering (construction, structural mechanics and CFD development via KLK Motorsport partnership), Model and Mould Design (including Class-A surface, cubing, rapid prototyping and aluminium precision casting), Precision Manufacturing (40 six-axis CNC milling machines with travel up to 14,000 x 6,000 x 4,500 mm, 10 NC turning centres, laser welding, wire-EDM), Composite/Lightweight (prepreg autoclaves up to 4,000 mm at 400°C/20 bar, RTM, a proprietary VPL/Vacuum Press Lamination process, and a 144-carrier braiding facility), Quality Assurance (1 µm precision coordinate measuring machines) and Individual Production (prototypes through exclusive small-series builds). The company also operates Selective Laser Melting (SLM) for metal additive manufacturing in aluminium, tooling steel, and titanium.

GERG serves enterprise customers in aerospace (Airbus CityAirbus NextGen rear structure and RACER front fuselage), automotive (BMW, Audi, Volkswagen, Rolls-Royce, Russo-Baltique, Marc Philipp Gemballa/Marsien), motorsport (Mercedes-AMG F1, McLaren, Austrian Luge Federation), medical technology (Highlight-360° surgical light), and consumer/industrial segments (Procair-300 UVC disinfection). Revenue is generated on a project-based, custom-quoted basis combining engineering hours, materials, and manufacturing time; no standardised pricing or licensing model exists. Go-to-market is exclusively direct enterprise sales driven by reputation, technical references and long-standing OEM relationships, supported by an in-house quality system certified to ISO 9001:2015, ISO 14001:2015, and TISAX.

The ownership base is the Gerg family, with Geschäftsführer Blasius Gerg sen., Maria Gerg, Blasius Gerg jun., and Martin Redweik. The company has no external investors, no disclosed parent, and no public funding rounds. It maintains a wholly-owned operating subsidiary, GERG Lighthouse, focused on automotive lighting. Forty years of reinvestment in proprietary processes (VPL developed 2005, aluminium precision casting 2012, SLM 2015) and capital equipment (Reiden RX18 commissioned 2024) anchor the operating profile.

Core offering

GERG is a contract manufacturer and engineering services provider offering custom precision manufacturing of prototypes, small-series components, and complete vehicles/structures. Core services span CNC machining (milling and turning), composite manufacturing (CFRP via prepreg autoclave, RTM, braiding, and proprietary VPL process), aluminium precision casting, selective laser melting (SLM) additive manufacturing, model and mould making, and integrated engineering and quality assurance. Deliverables are produced primarily for aerospace, automotive, motorsport, and medical technology clients.

Product overview

GERG GmbH is a full-service manufacturing and engineering company operating as a diversified industrial services provider rather than a single software product. The company offers six interconnected core service divisions: (1) Engineering covering construction, development, and process engineering; (2) Modelling & Mould Design with capabilities from design models to rapid prototyping and aluminium precision casting; (3) Precision Manufacturing including 40 CNC milling machines, 10 turning machines, and selective laser melting (SLM) for additive manufacturing; (4) Composite/Leichtbau featuring prepreg autoclave, RTM, proprietary VPL, and braiding technologies; (5) Quality Assurance with geometric and material testing capabilities; and (6) Individual Production combining prototyping through small series. Notable proprietary technologies include VPL (Vacuum Press Lamination) for CFRP components and aluminium precision casting. Notable projects include aerospace structures for Airbus (CityAirbus NextGen, RACER), motorsport components for Austrian Luge Federation, medical devices (Highlight-360°), and custom motorcycles (G2 Sharker).
