TW396107B - A manufacturing method for engineering plastic embossing roll - Google Patents

Abstract

A high limitation and heat resistance engineering plastic embossing roll can be used to replace conventional metal iron embossing roll, the pattern on the surface of the embossing roll is copied from nature pattern such as animal, plant and knitted fabric pattern. Copy the pattern by using silicone rubber and epoxy resin through repeated arrangement, binding, trimming, design, then make the silicone rubber cylinder. By injecting into mold and using transmission system and operating at low temperature of 20 DEG C to high temperature of 190 DEG C in conjunction with vacuum motor system and pressure system, the ready mixed engineering plastic compounding is injected by pressure into injecting mold to attach on the pattern of the silicone rubber cylinder, and formed to finish the engineering plastic embossing roll.
