Since the inception of the Company in 1981, Metaltech has steadily added its processing capability to build up a recognised multiple proficiency in the thermal processing of metals. Today the Company is heavily involved in vacuum gas atmosphere, controlled atmosphere and induction heat treatments offering a range of these specialist treatments both to U. K. and International clients.

Growing from an initial acquisition of several electric box furnaces and salt baths the Company introduced endothermic gas atmosphere furnaces into its portfolio in the mid-1980s. Today Metaltech has an extensive range of equipment for the general hardening needs of its customers which includes sealed quench furnaces, vacuum furnaces, tempering furnaces, and neutral salt hardening, austempering and martempering lines.

Induction heat treatment was into the Company's process capabilities in 1984 with the purchase of a high frequency motor generator set and several radio frequency units. Continuous investment has seen this sector grow to such an extent that the current inventory contains over 25 pieces of induction equipment which includes vertical and horizontal scanners, shaft and pin hardeners. Additionally our Company can claim an extensive range of innovative purpose built ancillaries constructed in-house by Metaltech engineers.

The Company's vacuum heat treatment processing capabilities have significantly expanded since the mid 1980s with the acquisition of several vacuum furnaces. To extend processing capability further the construction of an additional 5,000 sq. ft. unit has been undertaken giving a total operating area of 20,000 sq. ft. This additional space enables the planned expansion of several technologies to take place.

The Company has recently completed a £200k investment to install a fully integrated sealed quench and tempering facility which is currently being used to supply inert hardening and case hardening to the fastener and automotive industries.

As a result of this comprehensive array of equipment Metaltech can offer a broad range of heat treating services which include: austempering, martempering, though hardening, carburising and carbonitriding, nitriding, annealing, normalising, stress relieving, solution treatment, ageing, introduction hardening and tempering, flame hardening, vacuum hardening, tool steel hardening, austhenitic nitrocarburising, and jack tempering. In addition to carbon and alloy steels the Company has the capability to process cast irons, copper and nickel based alloys, heat resistant alloys, sintered material tool and die steels and a range of stainless steels.
