Powder metallurgy technology manufactures gears with excellent fatigue performance and dimensional accuracy to meet the stringent requirements of the motor manufacturing industry. Customized powder metallurgy gear processing, low noise, super wear resistance, high precision and high density occupy a place in the motor industry gear with its strong advantages .

Powder metallurgy gears have small tolerances in one-step molding, high precision, and a density of 90%. The precision and strength performance can be improved by shaping or repressing. The metal material loss of the conventional melting and casting method is 80%, and the PM is only 2%, and there is no need for subsequent mechanical processing, which saves costs again, and the production cycle is short. Compared with other processes, based on the manufacturing principle, reprocessing and other processes can be omitted, and mass production is rapid. ,Shorten the production cycle.

The main reason why powder metal gears are more popular than traditional gear materials is cost. In mass production, it is cheaper to make gears with powder metal than iron or steel. Less energy is used in the manufacturing process, and there is very little material waste. Considering that many powder metal parts do not require much (if any) mechanical finishing, manufacturing costs are usually lower.

Other characteristics that make powder metal attractive are related to the structure of its material, the porous composition of powder metal gears, which are light in weight and usually run quietly. In addition, powder materials can be uniquely mixed to produce unique characteristics. For gears, this includes the opportunity to impregnate porous materials with oil to produce self-lubricating gears.

Weight reduction, low noise, wear resistance and its cost-effectiveness, weight and energy saving are all important factors for the use of powder metallurgy gears in motor gears.
