Plastic Gears

Our precision plastic gears are manufactured via injection molding using high-performance engineering plastics such as POM, PA66, PA46, and PEEK. They come in various configurations, including single-stage gears, compound (dual/multi-stage) gears, and gears with integrated metal inserts. High-precision tooth profiles are achieved through precision molds and advanced injection molding processes. These gears transmit torque, adjust speed, and change the direction of motion through tooth meshing, serving as core components in micro-gearboxes and transmission mechanisms. We offer material selection, structural customization, and integrated insert development tailored to specific customer operating conditions.

Key Product Types

• Single-stage spur gears: Basic cylindrical transmission gears used for power transmission between parallel shafts; compatible with various standard reduction modules.

 

• Compound (dual/multi-stage) gears: Large and small gears molded as a single unit; enables multi-stage reduction within one part, streamlining gearbox internals and reducing mechanism size.

 

• Gears with metal inserts: Plastic bodies molded integrally with metal shafts or bushings; effectively prevents bore slippage and significantly enhances torsional strength and positioning accuracy; widely used in high-reliability applications such as automotive systems.

 

• Micro-precision gears: Small-module gears designed for compact motors; suitable for space-constrained micro-transmission systems.

Core Product Advantages

1. Low noise and self-lubrication: Engineering plastics possess inherent self-lubricating properties, resulting in quiet operation, reduced need for additional grease maintenance, and an improved overall user experience.

 

2. Lightweight design: Lighter than metal gears, helping to reduce equipment weight and lower overall energy consumption.

 

3. Suitable for mass production: The injection molding process allows for large-scale production, offering significant cost advantages.

 

4. High structural integration: Capable of forming complex compound structures (dual or multi-stage), reducing the number of components and simplifying customer assembly processes.

 

5. Moderate shock absorption: The plastic material offers a degree of toughness, absorbing impact loads during transmission and protecting the motor and the overall mechanism. Note: Plastic gears are suitable for low-to-medium torque applications; for high-load, high-temperature, or harsh operating conditions, metal gear solutions are recommended.

Application Areas
