High-precision injection molded plastic automotive gears, including spur gears and helical gears, widely used in vehicle transmission, steering and auxiliary systems. Made of wear-resistant engineering plastics, they ensure low noise, smooth operation and long service life. Custom specifications are available.
Our plastic automotive gears and helical gears are precision-engineered and manufactured via high-precision injection molding, designed to meet the demanding requirements of various vehicle systems. These gears serve as critical power transmission components in both traditional gasoline-powered vehicles and new energy electric vehicles.
Key Applications & Uses
✅ Transmission Systems: Helical gears for smooth and quiet power transfer in automotive gearboxes
✅ Steering Mechanisms: Precision plastic gears for steering column adjustment and power assist systems
✅ Auxiliary Motors: Gears for window regulators, wiper motors, door lock actuators and seat adjustment mechanisms
✅ EV Systems: Lightweight plastic gears for electric vehicle auxiliary drives and cooling fan assemblies
Performance & Advantages
✅ High Wear & Fatigue Resistance: Made of premium engineering plastics (POM, PA66 with glass fiber reinforcement), offering excellent wear resistance and long service life under continuous high-load operation.
✅ High Dimensional Accuracy: Strict tolerance control guarantees consistent fit and compatibility with mating parts, reducing assembly errors and enhancing transmission efficiency.
✅ Lightweight & Cost-Effective: Compared to metal gears, our plastic gears reduce vehicle weight, supporting lightweight design goals while offering significant cost advantages without compromising performance.
✅ Customization Available: We provide one-stop custom services, including gear design optimization, mold development and mass production, to meet your specific requirements for different sizes, tooth profiles, materials and performance specifications.
