Vacuum Furnaces

AMG Engineering, based in Hanau, Germany, designs, engineers and produces advanced vacuum furnace systems. AMG supplies technologically-advanced vacuum furnace systems to the automotive, aerospace, energy (including solar and nuclear), superalloys and specialty steel industries. Examples of metallurgy furnace systems produced by AMG include vacuum remelting, solar silicon melting and crystallization, vacuum induction melting.

AMG’s vacuum furnace systems are integral in the advancement of product technology in high growth industries, such as automotive, aerospace and solar energy. In aerospace, AMG is a world leader in the production of vacuum furnaces for titanium production, which is critical in the design of new lightweight planes for greater fuel efficiency. AMG is also the global leader in electron beam vacuum furnaces for coating turbine blades, which enable the turbine blades to withstand the heat of the engine. These vacuum metallurgical processes allow large-scale mass production of turbine blades, which reduce fuel consumption by up to 30% and emissions by 15% and more.

In solar energy, AMG’s silicon melting and crystallization furnaces provide customers with high-purity polysilicon solar wafers that deliver some of the highest sunlight-to-energy conversion ratios in the industry.

AMG also designs and produces vacuum heat treatment and high pressure gas quenching, vacuum precision casting, turbine blade coating and sintering.

AMG Engineering furnace systems include:
  • Vacuum remelting
  • Turbine blade coating
  • Sintering for nuclear fuels and high purity metals
  • Precision casting
  • Solar silicon melting and crystallization
  • Induction melting
  • Vacuum case-hardening heat treatment
  • Plasma carburizing
Own and Operate - AMG Engineering provides vacuum carburizing and high pressure gas quenching of case hardening steels services to customers in the transportation industries.

AMG plans the project, makes the investment, and if necessary, builds a new facility where the heat treatment process is performed for the customer on a long term tolling basis.

AMG operates in 4 such facilities today - in Germany, the United States and Mexico.

AMG Engineering operates under the ALD Vacuum Technologies brand name. Further information available at:
