[Custom-made Machines]

The photo shows the heating station of an automobile engine
camshaft pump cam induction heating machine.

To austemper the ductile iron pump cam, the cam is heated to over 1,100°C
and quenched in the adjacent salt bath.

To effectively heat the triangular shaped target area,
the rotating workpiece is heated with low frequency using a multi-turn coil
until a certain depth is reached.

After thorough calibration, we were able to meet the severe
heating specifications of minimum 1,100°C and range ±20°C
for two differently shaped target areas.
