ALD Vacuum Technologies GmbH
Treatment equipment and furnaces
Company Overview and Heritage
ALD Vacuum Technologies GmbH, a key division within 'AMG Engineering' and a subsidiary of AMG Critical Materials N.V., specializes in providing advanced equipment and systems for the thermal and thermochemical treatment of metallic materials. With roots tracing back over 150 years to pioneers like Heraeus, Leybold, and Degussa, ALD has evolved into a global leader. Headquartered in Hanau, Germany, the company operates worldwide with approximately 900 employees across 10 countries, leveraging extensive expertise in vacuum process technology and custom-tailored system solutions.
Core Products and Services
ALD's offerings span two primary areas: Vacuum Metallurgy and Vacuum Heat Treatment. In Vacuum Metallurgy, ALD designs and supplies systems for treating liquid metallic materials, including vacuum systems for melting, casting, and remelting of metals and alloys—such as those used in solar cells—and specialized coating equipment for turbine blades. Key technologies include Vacuum Induction Melting (VIM), Electro Slag Remelting (ESR), Electron Beam Melting (EB), Plasma Arc Melting (PAM), and advanced Metal Additive Manufacturing (VIGA, EIGA, EBuild). The company also provides Silicon Crystallization Units (SCU) and Hot Isothermal Forging (HIF) systems.
For Vacuum Heat Treatment, ALD manufactures vacuum furnaces for processes such as annealing, hardening, tempering with high-pressure gas quenching, low-pressure carburizing, high-temperature brazing, and over-pressure sintering. These systems are critical for enhancing the properties of tools, high-precision engine parts, fuel injectors, and transmissions, as well as for sintering high-strength cemented carbides and special oxides. Complementing its core equipment, ALD offers 'ALD EXPERT' digital transformation solutions and comprehensive after-sales services, including a global network of certified engineers, strategically located spare parts warehouses, and a personalized webshop for efficient support.
Market Impact and Innovation
ALD Vacuum Technologies serves high-growth industries including automotive, aerospace, energy, and specialty metals. The company's innovations contribute to critical advancements such as reducing structural weight in aircraft through titanium production and advanced alloys like Gamma Titanium Aluminide, and improving fuel efficiency with electron beam technology for turbine blade coatings. ALD's solutions also support CO2 reduction efforts in the automotive sector by enabling efficient transmissions and injection systems, and contribute to renewable energy through high-purity polysilicon solar wafer production. The company emphasizes continuous research and development, strategic alliances, and a commitment to sustainability and ethical business practices.
