About GH Induction
GH Induction (GH Electrotermia, S.A.U.) is a manufacturer of induction heating solutions founded in 1961, with headquarters and manufacturing plant in San Antonio de Benagéber near Valencia (Spain). The company develops and manufactures custom induction systems, compact vertical induction machines of the TVK family, IGBT and SiC generators, and inductors – both conventionally manufactured coils and, since 2014, patented pure-copper inductors printed by electron beam melting (EBM) (3DPCoil). The systems are used in processes such as induction hardening, tempering, annealing, brazing, bonding, shrink fitting, tube welding and heating for forming. Customers come from automotive, commercial vehicle and heavy machinery engineering, foundry, tool industry, electric motor manufacturing and rail technology; reference customers include Alstom, ITM Group, Sandvik and Renault. In addition to the headquarters, the group maintains its own companies in Germany (Hirschhorn), France, USA, India, China, Brazil and Mexico, among others, as well as a representative office in Poland, and serves more than 5,000 customers worldwide.
