YJ Eyewear Series Injection Molding Machines

In the eyewear industry, the raw materials, including TR, PC, and TPR, are featured with high prices and special performance. The crucial points of the molding process are adequate mixing of molten plastics, precise temperature control, high injection pressure, high injection speed, and product size repeatability. As a machine manufacturer, we should design high-performance and targeted machine configurations.

After extensive market research and stringent quality testing, YOUZU launched the second generation of YJ Eyewear Series injection molding machines, which have solved the common problems in the eyewear industry and won praise from domestic and overseas users, adhering to the mission of satisfying customers and creating more value for society.

Screw Tip Assembly Linear Guide
Electroplated high hardness screw sets, residual material easy to clean, prevent black spots, miscellaneous colors, and corrosion of screw. Linear guide rails with a thickened frame, which achieve the lowest mechanical movement resistance & support high-speed injection actions.
And repeated injection position accuracy to be 0.1mm tolerance.
Copper-Alloy Slides Large-Diameter Oil Circuit
The movable platen has copper-alloy double slides that reduce resistance when opening and closing the mold at high speed, ensuring long-lasting mechanical movement. Adopt large-diameter oil circuit with low internal resistance control method to improve the response tempo and repeat accuracy of action.
