Flame Hardeners

We are specialists in Gear teeth hardening and press tool moulds.

Flame hardening involves the direct impingement of oxy-acetylene gas flames from suitably designed and positioned burners onto the surface area to be hardened, followed by quenching.

Depth of hardening is controlled by the design of the flame head, time of heating and the hardenability of the material. Again, hardening can be single-shot or progressive.
