Vacuum Furnace Engineering Limited - The Specialists in Vacuum Furnace Technology

Plasma Arc Melting
Plasma Arc Melting (PAM) offers customers the ability to improve the properties of conventional alloys, as well as the potential for developing and producing new complex alloys. Retech is the industry leader in the production of the PAM furnace, which utilises an arc in a non-reactive gas, as a heat source and is applied to the melting of reactive and refractory metals.

Plasma Arc Melting systems built by Retech are qualified for the production of rotating grade Titanium. We offer PAM furnaces in capacities ranging from laboratory to production scale units, powder production, cold hearth refining (single or multiple hearths) and single torch systems for scrap consolidation. In addition, Retech operates one of the world's largest and most comprehensive plasma research programmes; as a commitment to remain the world's foremost producer of Plasma Arc Melters, more than 200 alloys have been melted in our research facility.
