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 high-speed slope protection plastic mold is injection molded by polypropylene pp. this method is to melt the plastic material and then inject it into the membrane cavity. Once the molten plastic enters the mold, it is cooled and shaped according to the mold cavity. The resulting shape is often the final product and no further processing is required before installation or use as the final product. Many details, such as bumps, ribs, and threads, can be molded in one step of injection molding.
