The molding machine is a specialized equipment for the formation of white areas in lost foam molding. It is made of expandable polystyrene (EPS) or copolymers as raw materials,after foaming, drying, and aging treatment, the EPS and copolymers are automatically fed into the mold by this machine, and then heated and melted into shape by steam. after cooling and shaping, the foam products are automatically separated from the mold by compressed air.
