Heat treatment is the key process to make sure that bearing materials with a high level of characteristics. HCH has seven computerized protective atmosphere heat treatment lines which integrates with automatic material loading, cleaning and drying, quenching, re-cleaning and tempering, so that help HCH bearing materials reach high level characteristics of hardness, high rolling contact fatigue resistance, excellent wear resistance, dimensional stability as well as excellent mechanical strength, further guarantees HCH bearings of long life expectancy.

Besides, the Group also introduces vacuum furnace heat treatment device.
