PA Gear

Factory & Production Capacity

We specialize in precision injection molding and custom engineering plastic gear manufacturing, equipped with high-precision injection molding equipment and gear-specific mold processing systems with over ten years of industry experience. The product dimensional and tooth profile tolerance is steadily controlled within ±0.02 mm, with a daily output of 100,000 pieces. We provide one-stop services from mold development and injection molding to post-processing, serving customers in office equipment, automotive electronics, home appliances and industrial automation industries.

Technological Process

1. Mold Design & Fabrication: Optimize tooth profile structure based on drawings and manufacture high-precision gear molds to ensure tooth profile accuracy and consistency.
2. Material Preparation & Drying: Select PA raw materials and dry them to prevent defects such as air bubbles and silver streaks during injection molding.
3. Precision Injection Molding: Melt materials at high temperature, inject into molds under high pressure, and form the main body of the gear in one piece.
4. Deburring & Trimming: Remove gates and burrs, and finely trim the tooth profile and inner hole to ensure smooth and jitter-free transmission.
5. Surface Treatment (Optional): Conduct polishing, lubricating coating and other treatments as required to optimize transmission performance.
6. Full Inspection & Delivery: Inspect product dimensions, tooth profile accuracy and appearance, then pack and deliver qualified products.
