About us

ALD Vacuum Technologies
is a synonym for innovation in vacuum technologies. ALD is a leading supplier of vacuum furnaces and processes. We operate in all fields of vacuum metallurgy and vacuum heat treatment. With subsidiaries in the USA, France, China, Japan, India, Singapore, and Thailand and over 70 representatives, we are serving our customers.

ALD's primary and re-melting technologies produce high grade materials and alloys. The main focus is on steels, nickel based alloys and special materials like Titanium and the products thereof like ingots, investment castings or metal powder.

Innovation and continuous ongoing developments of technologies and systems for heat treatment and sintering are leading to quality improvements of the treated components while cutting costs.

Products and services

ALD Vacuum Technologies develop and manufacture vacuum furnaces for vacuum metallurgy and heat treatment.

In vacuum metallurgy all ranges of primary melting and re-melting are covered. Vacuum Induction melting furnaces are used for the primary melting of steel and casting to an ingot or to molds for investment casting. Electro Slag Re-melting and Vacuum Arc Re-melting increase the homogeneity of the alloys.

Special systems for the melting and casting of Titanium alloys are available.

The vacuum heat treatment include all systems from multipurpose single chamber furnace, vacuum carburizing system, brazing furnaces and nitriding systems. Carburizing systems are available for high pressure gas and with oil quenching.

All ALD systems are available from small laboratory systems up to production systems and/or mini steel mills.

Beside the furnace system ALD supports the customer with process engineering, development of customer processes for vacuum metallurgy and heat treatment.

MonoTherm Heat Treatment System

MonoTherm Heat Treatment System

MonoTherm is a single chamber multipurpose furnace for all heat treatment application, such as hardening, case hardening, annealing, tempering, brazing.
The hot zone will be cylindrical or cubical. Four different furnaces sizes from 400x400x600 mm to 1200x1200x1500 mm are available.
The charge weight will be from 200 to 2000 kg. The vacuum level could be down to 5x10-6 mbar. The maximum quench pressure is 20 bar. Dynamic quenching allows a gentle cooling of the load.

DualTherm Oil Quench

DualTherm Oil Quench

The DTO is a furnace system for the process of vacuum carburizing and oil quenching. Two charge sizes with 400 x 400 x 600 mm and 600 x 750 x 1000 mm are available. The maximum charge weight is 1000 kg.
Vacuum carburizing replaces the gas carburizing and has the advantage of no oxidation. The quenching under inert gas avoids any flames.
The DTO could be installed in a normal production environment and reduces the costs for the carburizing significantly.

Vacuum Induction Melting (VIM/VID)

Vacuum Induction Melting (VIM/VID)

Vacuum induction melting and de-gassing for higher alloyed steels, such as tool & die steel, stainless, duplex steel and Nickel based alloys. The absence of air avoids pick up of und desired element like Hydrogen, Oxygen and Nitrogen.
Modification at these systems allows continuous and investment casting as well as powder making by gas atomisation
The product range is from laboratory scale with one litre to pilot and smaller production up to 3.000 litres (23 tons)
