Surface Technology Coatings, a division of Sutton Tools , has a state of the art Abar-Ipsen Turbo Treater vacuum heat treatment furnace, which features high pressure 12-bar gas quenching and convection assisted heating using patented Abar-Ipsen flapper nozzles, thereby providing a high level of temperature uniformity.

Measuring 600mm wide x 600mm high x 1000mm long, the furnace has a maximum load of one tonne, and is capable of hardening large tools or components commonly seen in plastic injection moulding or high pressure die-casting.

As it is a vacuum furnace, no scale, oxidisation or decarburisation occurs during the process. The convection assisted heating capability provides excellent temperature uniformity (+/- 5ºC) and reduces process time, resulting in improved turnaround times.

The TurboTreater utilises 360º quenching and has the ability to perform a step quench or isothermal hold to minimise distortion and hence reduce machining allowances.

The 300hp fan used to deliver the quenchant gas into the furnace and the ability to quench at 12-bar optimises the microstructure and hence mechanical properties of the steel.

Sutton Tools states that the new furnace represents a significant capital investment in the future of Australian tool and die making. This coupled with the metallurgical expertise within the company will offer tremendous opportunities for any client seeking premium quality vacuum heat treatment.

The new furnace will work alongside Surface Technology Coatings two existing Abar-Ipsen furnaces and with a seven day operation, customer service will be significantly improved.

The Surface Technology Coatings division of Sutton Tools is the only commercial facility in Australia offering high pressure quench vacuum heat treatment, plasma nitriding and PVD hard thin film coatings under the one roof.

The division carries out research and development with Australia's leading Universities and research organisations to develop innovative services that keep STC at the forefront of heat treatment and surface engineering technology.
