| 高速护坡塑料模具是由聚丙烯pp注塑成型的，塑料注塑成型这种方法即是将塑料材料熔融，然后将其注入膜腔。 The plastic mould for high-speed slope protection is made by injection moulding of polypropylene and polypropylene. This method is to melt the plastic material and then inject it into the film cavity. 熔融的塑料一旦进入模具中，它就受冷依模腔样成型成一定形状。所得的形状往往就是最后成品，在安装或作为最终成品使用之前不再需要其他的加工。许多细部，诸如凸起部、肋、螺纹，都可以在注射模塑一步操作中成型出来。 Once molten plastic enters the mould, it is cooled and shaped into a certain shape according to the cavity pattern. The resulting shape is often the final product, and no other processing is required before it is installed or used as the final product. Many details, such as bulges, ribs and threads, can be formed in one step of injection moulding |
