Haitian injection molding machine 180T screw diameter (structure) Injection apron Accessories / Jinxin screw factory apron is the role of non-return. It is to prevent a part of the plastic melt during injection future leaks. EM-30L agents at work, and a plastic apron over meson (over pad ring) form a closed contact structure EM-30L joined to prevent the plastic melt leakage. A great relationship between the speed of injection molding machines and sophistication of product weight and a plastic apron over meson Zhini action. And an apron motor response speed of EM-30L, is a non-return action by its stroke, sealed lamination time, leaving a plastic head and time factors. Good plastic head, over apron, combined with a plastic meson can achieve high precision injection volume control. Especially in transparent products, precision molding, the plastic head, over apron, plastic meson effect is manifested.
