About the Aichelin Group
AICHELIN Holding GmbH, headquartered in Mödling, Austria, develops and manufactures industrial furnace systems for the heat treatment of metal components. The product portfolio includes chamber furnaces, all-in-one vacuum furnaces, integral quench furnace lines, rotary hearth furnaces, mesh belt conveyor furnaces (Safed BD series), battery 2-level roller hearth furnaces, and vacuum furnaces for hardening, annealing, brazing, and gas quenching. Through its subsidiary NOXMAT, the company also manufactures industrial burners and heating systems. The materials processed range from steel to titanium and nickel alloys through to battery materials such as LFP and NMC cathode materials. The group serves industries including automotive, aerospace, toolmaking, mechanical engineering, as well as the battery, electronics, and medical technology industries. In addition to furnace systems, Aichelin supplies spare parts (over 200,000 parts in stock), repair, modernization, and lifecycle services, also for third-party equipment. Locations are situated in Austria, Germany, Slovenia, Turkey, China, and the USA.

Materials and Processes
Vacuum Heat Treatment
Oxygen-free heating and controlled cooling of steel, titanium and nickel alloys without scale formation.
Vacuum Hardening
Process for increasing the hardness of metals, especially steel.
Vacuum Annealing
Stress relief and recrystallization without oxidation of the component surface.
Vacuum Brazing
Oxide-free, solid brazed joints for aerospace, electronics, and medical technology.
Low-Pressure Carburizing (LPC)
Targeted improvement of the surface hardness and wear resistance of steel materials under reduced pressure.
Gas Quenching
Uniform, low-distortion cooling with gases such as nitrogen, helium, or argon.
Gas Nitriding
Nitrogen diffusion to increase hardness as well as wear and corrosion resistance.
Calcination
Thermal treatment of battery materials such as LFP and NMC cathode precursors at 700–1,100 °C.
NOXMAT Industrial Burners
Burner and heating systems for thermal process plants with high energy efficiency.
