Product Description

High Injection Speed Screw and barrel

The design concept of the low-shear optical screw is based on the fast heat accumulation and low melt flow index of optical resin. The requirements on injection pressure and the rate of injection are relatively high during injection molding. For many years, Huaye has been improving the material selection and structural design to achieve the best quality, and different screw structure solutions are invented in response to different product requirements, a special low-shear, high-pressure geometric structure has been developed.
