The plastic slope protection mold is generally made of Engineering polypropylene plastic through injection molding by injection molding machine. The common patterns are rectangular slope protection, hexagonal slope protection, splay slope protection, herringbone slope protection and arch slope protection. The slope protection brick is mainly used to prevent water and soil loss. The concrete is placed in the slope protection brick mold. After vibration molding on the shaking table, a piece of cement slope protection is made after the cement solidifies. The injection mold for slope protection brick is mainly used to produce high-speed slope protection brick. The dam cement slope protection brick is used. The concrete is placed in the mold box for vibration molding, and can be used after natural solidification and drying.
