盖板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。
The raw materials of the cover plate model generally include plastic injection molding and sheet steel model molding. The plastic model of the cement drainage ditch cover plate is made of polypropylene plastic particles and injected into the prepared drainage ditch cover plate mold cavity after high-temperature treatment by the injection molding machine. The cover plate model is formed after cooling treatment. The steel model of the cement drainage ditch cover plate is curled and cut with 3-8mm iron plate , modeling, reinforcement, welding, assembly, grinding and other procedures.
