Plastic laboratory extruder is suitable for the mixing and processing experiment of engineering plastics, modified plastics, waste plastics, and masterbatch. It has the functions of plasticizing homogenization, coloring proofing, filling modification and so on. Equipped with different types of heads, molds, and auxiliary machines can be used for plastic profiles, pipes, sheets, and pellet production. It can also be used for co-extrusion of pipe marking lines.
