On the difference between forged gears and cast gears

With the enhancement of forging technology and the lightweight requirements of automobiles, cast gears have gradually been eliminated by gear companies, and the automotive gear manufacturing industry has begun to apply more forging forming technology. Gear precision forging forming is a high-quality, efficient and low-consumption advanced manufacturing technology. In recent years, it has been widely used in the mass production of automotive toothed parts.

Characteristics of forged gears:

1. The internal structure of forged gears is dense, high strength and long life.

2. Not only is the appearance beautiful, the working hardness is also greatly improved, and it contains very few impurities.

3. The explosion-proof performance is more reliable and higher in level, and can be used in strict working conditions.

Characteristics of castings:

1. The internal structure of castings is worse, the strength is low, and it is easy to have sand holes, shrinkage, and easy to break and deform.

2. It can be used under general working conditions, and the explosion-proof level is lower than that of forging process tools.

3. There are more oxide scales on the surface, and it is difficult to remove them even with oxide scale cleaning machines.

At present, the country advocates green environmental protection, and castings have gradually been listed as obsolete series. Those who have the conditions have changed from casting to forging. Because of market demand, it is normal for everyone to face transformation. The greater the demand, the higher the requirements for the process, so if you want higher precision gears, you can add Litai oxide skin cleaning machine.
