水泥盖板塑料模具属于盖板塑料模具的一种，用途不同，水泥盖板塑料模具是用于生产水泥盖板的专用模具，水泥盖板模具是铁路预制模具中的一种，盖板塑料模具 是专门用于生产高速公路，高速铁路用的电缆沟盖板和水沟盖板使用。盖板塑料模具采用工程聚丙烯pp的材质，这种材质具有很好的韧性，可溶性和可塑性， 塑料颗粒高温下化成液态，是液体流入特定好的铁模具中，利用液态水循环使其冷却，盖板塑料模具就根据盖板钢模具的规格而塑型。
The plastic mold of cement cover plate belongs to one kind of plastic mold of cover plate, which has different uses. The plastic mold of cement cover plate is a special mold for producing cement cover plate. The plastic mold of cement cover plate is one of the railway prefabricated mold. The plastic mold of cover plate is specially used to produce cable trench cover plate and water ditch cover plate for highway and high-speed railway. The plastic mould for cover plate is made of polypropylene PP, which has good toughness, solubility and plasticity. The plastic particles turn into liquid at high temperature. The liquid flows into a specific good iron mold and is cooled by the liquid water circulation. The plastic mold for the cover plate is molded according to the specification of the steel mold for the cover plate.
