Custom High Precision Injection Mold for Plastic Gears

Mold Machining

In the machining of tooth shapes, spur gears are machined by slow wire-cut EDM to achieve a smooth surface roughness on the tooth profile.

It is essential that both plates A and B are processed concurrently with slow wire-cut EDM to guarantee accurate coaxial alignment.

For standard gear ring inserts, once the tooth shaping process is finished, any subsequent grinding machine processing is not permissible due to the workpiece's thickness.  Such processing could create lateral burrs on the tooth surface, potentially resulting in the workpiece being scrapped.  In cases where further processing is unavoidable, EDM machining is the only viable option.

These steps highlight the precision and care required in the machining of gear components, ensuring that each part meets the stringent standards of quality and functionality.

At GV MOLD, our team of professional molding experts employs the latest injection machines equipped with processing control units. We operate within a complex window, meticulously controlling the precision of molding temperatures, injection pressures, cooling processes, and other variables. This ensures that every molding cycle and each cavity maintain the same molding temperature and cooling rate, guaranteeing the precision of the plastic molded gears meets high-precision requirements.
