Screw Tip Assembly		Linear Guide

With electroplated high hardness screw sets, residual materials are easy to clean to 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.
