Plastic Gear Forming


Plastic gear forming is a manufacturing process used to create gears made of plastic materials. This article explores the various aspects of plastic gear forming and its applications in different industries.

Types of Plastic Gear Forming

1. Injection Molding

2. Extrusion

3. Compression Molding

Injection Molding

Injection molding is a common method of plastic gear forming. It involves injecting molten plastic material into a mold cavity, where it solidifies and takes the shape of the gear. This process allows for the production of complex gear designs with high precision.


Extrusion is another technique used in plastic gear forming. In this process, plastic material is forced through a die to create continuous profiles of gears. It is a cost-effective method for producing gears with uniform cross-sectional shapes.

Compression Molding

Compression molding is a suitable choice for manufacturing large plastic gears. The process involves placing a pre-measured amount of plastic material in a mold cavity and applying heat and pressure to shape it into a gear. Compression molding offers excellent strength and durability.

Advantages of Plastic Gear Forming

1. Cost-effective compared to metal gear manufacturing.

2. Lightweight, making them ideal for applications where weight reduction is important.

3. Wear resistance and low friction properties.

4. Excellent corrosion resistance.

5. Can be produced in various colors for aesthetic purposes.

Applications of Plastic Gears

1. Automotive industry: Plastic gears are used in various automotive applications, including power windows, seat adjustments, and HVAC systems.

2. Consumer electronics: Plastic gears are found in devices such as printers, scanners, and DVD players.

3. Medical equipment: Plastic gears are used in medical devices for precise and controlled movements.

4. Industrial machinery: Plastic gears find applications in industrial equipment such as conveyor systems and packaging machinery.


Plastic gear forming is an essential process in manufacturing gears from plastic materials. Its versatility, cost-effectiveness, and unique properties make plastic gears suitable for a wide range of industries and applications. The advancement of plastic gear forming techniques continues to expand the possibilities for gear design and performance.
