ALD Vacuum Technologies supplies equipment and systems for thermal and thermochemical treatment of metallic materials in solid and liquid form. The company’s competence consists on the one hand of its mastery in vacuum process technology and on the other hand of its know-how in designing custom-tailored system solutions for use in these fields.

ALD is noted for its superb know-how basis, high investments in research and development and its strategic alliances. Close collaborations with well-known manufacturers in operator companies have strengthened its position as a supplier of key technologies to major growth markets.

Vacuum Metallurgy involves designing and supplying systems and processes for treating metallic materials in liquid form – particularly vacuum systems for the melting, casting and remelting of metals and alloys, metals for solar cells as well as special coating equipment for turbine blades.

Vacuum Heat Treatment includes vacuum furnaces for heat treating metallic materials. Such equipment is used for heat treating of tools, high precision parts for engines and fuel injectors as well as for transmissions. Sintering of high strength cemented carbides and special oxides is also a part of heat treatment.

Heat Treatmnet Services (HTS) offerings are primarily aimed at customers who do not wish to invest in their own facilities, but who wish to benefit from all the well-known and repeatedly demonstrated advantages of the heat treatment technology developed by ALD.

After Sales and Services create an individual service package for each of our customers based on the experience of thousands of furnaces in the market. ALD Service is adapted to your unique requirements, exactly like our furnaces.
