| 盖板模型模型模型的原材料一般有塑料注塑成型与钣金钢模型成型两种，水泥排水沟盖板塑料模型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排水沟盖板模流水槽模具 u型槽模具 电缆槽模具 隔离墩钢模具 护坡砖模具 钢制闸门 螺杆式启闭机 卷扬式启闭机腔当中，待经过冷却处理之后成型盖板模型；水泥排水沟盖板钢模型以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。 There are two kinds of raw materials for the model model of cover plate: plastic injection molding and sheet steel model molding. The plastic model of the cover plate of the cement drainage ditch is made of polypropylene plastic particles, which are injected into the prepared cavity of the cover plate of the drainage ditch after high-temperature treatment by the injection molding machine, and then the cover plate model is formed after cooling treatment. The steel model of the cover plate of the cement drainage ditch is made of 3-8mm iron plates, which are rolled Song, cutting, modeling, reinforcement, welding, assembly, grinding and other procedures from the production |
