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, Vacuum Hardening Furnace

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.

Vacuum Induction Melting and De-gassing

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)

Vacuum Inert Gas Atomization

Vacuum Inert Gas Atomization (VIGA) or Electrode Inert Gas Atomization (EIGA) is only way to produces real spherical metal powder, which is the raw material of additive manufacturing processes such as 3D printing, metal injection molding, Kinetic fusion, etc.

The typical powder size is between 20 and 80µm (d50 value).
VIGA is using a crucible and is applicable for all kind of steels. EIGA is a contactless melting preferable for reactive and high melting materials (Ti, Zr, W, Hf, etc)
