排水沟盖板模具生成原理       排水沟盖板模具，水沟盖板模具 的原材料一般有塑料注塑成型与钣金钢模具成型两种，沟盖板模盒采用聚丙烯塑料颗粒状经过注塑机高温处理注入预先准备好的渠道沟盖板模腔当中，待经过冷却处理之后成型沟盖板模盒；沟盖板钢模具以3-8毫米的铁板经过卷曲，裁切，造型，加固，焊接，拼装，打磨等多道手续制作而成。

Drain cover mold forming principle of drain cover mold, raw materials are generally ditch mold of plastic injection molding and mold steel plate two, trench cover die box using polypropylene plastic injection molding machine after high temperature treatment into the granular channel prepared a cover plate cavity, stay after cooling treatment after forming a trench cover die box; trench cover steel mold with 3-8 mm plate after cutting, crimp, shape, reinforcement, welding, assembly, polishing and other multi-channel formalities made.
