Precision Injection Molded Plastic Gear

Spur gears with a central bore and uniform tooth profile designed for smooth rotational transmission in mechanical assemblies. The structure features precise involute teeth to ensure consistent meshing and efficient torque transfer, suitable for use as drive or idler components in compact mechanisms.

Manufacturing relies on high-precision injection molding to maintain tight tolerances on the outer diameter, root circle, and bore dimensions. Controlling shrinkage rates is critical to achieving accurate tooth geometry and minimizing backlash during operation. Surface finish requirements focus on low friction and wear resistance at the contact points to extend service life under load.

Production capabilities include processing a range of engineering plastics such as POM, PA66, and PEEK to meet specific needs for strength, chemical resistance, and temperature stability. The facility utilizes advanced Fanuc and Engel injection molding machines alongside ISO 9001 and IATF 16949 certified quality systems to ensure dimensional consistency across batches. Quotation depends on material selection, gear module, quantity, and any secondary machining operations required for the center hole or keyway.
