Cast Steel Gear Foundry in China, Steel Casting Automobile Gear
Factory, Gear Casting Workshop
With the development of science, almost metal gears turned
plastic gears slowly. Because plastic gear has more lubrication
and wear resistance which reduce the noise, cost and the
The commonly used plastic gear materials: PVC, POM, PTFE, PA,
nylon, PEEK, etc.
The life of the automobile gear is mainly composed of two major
One is the contact fatigue for gears; the other is the bending
fatigue strengths of gears.
The former is mainly decided by carburizing quenching quality,
the latter is mainly decided by the gear material.
Powder metallurgy gear is the product of high and new technology
with no or less cuttings.
