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。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。

The plastic mold for high speed slope protection is molded by polypropylene PP. Plastic injection molding is a method of melting plastic material and then injecting it into the film cavity. Once the molten plastic enters the mold, it is formed into a certain shape by the cold mold cavity sample. The shape of the product is often the final product, and no other processing is needed before the installation or as the final product is used. Many details, such as protrusions, ribs, and threads, can all be molded in an injection molding one step.
