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.
