According to the size and size of the mold, the required injection molding equipment can also be divided into different sizes. According to the size and weight of the cement slope protection, the size of the injection molding equipment is determined. The engineering polypropylene is used as the raw material for injection molding. This plastic has high anti-wear and aging strength, The prefabricated slope protection steel mould and the cast-in-situ slope protection steel mould must be produced with pure raw materials. If waste materials are added, the service life of the slope protection mould will be affected. Under normal circumstances, the service life of the prefabricated slope protection steel mould and the cast-in-situ slope protection steel mould is 200 times in 2 years.
