LSZ series twin screw conical extruders are high effective extrusion equipments, they outperform conventional extruders in self-cleaning, raw material feeding, ventilation, enabling chemical reaction, and uniformed mixing and melting. This extrusion equipment is especially suitable for processing thermal-sensitive plastics. It plays more significant use in the extrusion of PVC powder. When connected to an extrusion die and other downstream components, this powerful extrusion machine can turn various thermoplastics directly into pipes, profiles, sheets, plates etc. It is also the right equipment to use in plastic modification and pelletizing.
