The application of plastic gears has become more and more extensive. Compared with metal gears, it has many advantages, especially in cost, design, processing, and performance.

The design of plastic molding is not subject to too many constraints, and can efficiently manufacture gears in a short time. At the same time, the application fields of plastic gears are also wider than metal gears, so they promote the development of gears to withstand higher loads and transmit more power. The plastic gear is also an important material to meet the requirements of low-quiet operation, which requires high-precision, new tooth shape, and excellent lubricity or flexibility.
