We can provide quality heat treatment and metallurgical services in partnership with Quality Heat Treatment Ltd. Established in 1997, this company is our close associate and one of New Zealand’s leading contract heat-treaters.


Our heat treatment facilities are in Auckland and Christchurch, providing service to the engineering and manufacturing industries on both islands. At each one, qualified staff manage and provide the necessary treatments and assist with material selection.

 Materials we can process

Equipment

 

Our heat treatment facilities use fluidised bed furnaces for a variety of processes. They have inert/neutral atmospheric protection which provides decarb/oxidation-free surfaces (no scale) on all processed work. A large capacity and range of furnace sizes allows us the flexibility to provide quick processing times.

To reduce our footprint as much as possible, we use electric heating – which means we can take advantage of clean, non-polluting, renewable energy.

Delivery Lead Times

It's nice to know how long you can expect your project to take, and we aim to deliver as promised.

Heat treatment process parameters can be tailored to material manufacturer's specification or client specification instructions. There is no need for clients to hold back work for weekend processing.
