What ALD Vacuum Technologies does

ALD Vacuum Technologies GmbH is a Hanau, Germany-headquartered manufacturer of vacuum equipment for metallurgy and heat treatment, operating as the AMG Engineering division of AMG Critical Materials N.V. The company employs approximately 1,000 people across nine countries and runs two primary product platforms: Vacuum Metallurgy (covering vacuum induction melting, vacuum arc remelting, electro slag remelting, electron beam melting, plasma arc melting, vacuum investment casting, thermal barrier coating via EB-PVD, silicon crystallization, powder atomization, and industrial additive manufacturing via the EBuild system) and Vacuum Heat Treatment (DualTherm, ModulTherm, SyncroTherm, MonoTherm multi-chamber furnaces, plus VKP sintering systems). These systems are built around proprietary vacuum process technology and decades of metallurgical know-how, targeting high-temperature, high-purity applications.

ALD generates revenue through a mix of one-time capital equipment sales (custom-quoted, multi-year enterprise contracts), contract processing services (Heat Treatment Services at facilities in Germany, USA, Mexico, and China employing ~300 people), toll melting services (electron beam), engineering services (LPC process development), and recurring after-sales including spare parts (with a 2%-discounted web shop) and modernization/retrofit programs. The ALD EXPERT digital suite adds an Industry 4.0 software layer for monitoring the installed base of thousands of furnaces.

The company sells to enterprise customers across automotive (transmission, fuel injector, gear heat treatment), aerospace (turbine blades, titanium aluminides, isothermal forging), energy (solar silicon crystallization, nuclear fuel via the NewMOX subsidiary), and specialty metals (refractory and reactive metals). Distribution runs through wholly-owned subsidiaries in Germany, the United States, Mexico, China, India, Japan, Thailand, and France with dedicated sales contacts organized by product line. The customer base is enterprise-only, served via direct field sales, with named installations including Daido Steel (VAR plants operational 2024-2025) and Safran Aircraft Engines (isothermal forging module).
