Product Overview
SJZ series conical double screw extruder, die and corresponding with the auxiliary equipment, can be a variety of thermoplastic plastics especially hard poly vinyl cyanide direct powder extrusion into pipe, plate; sheet, film and profile, but also can complete the modifying and pelleting of all kinds of plastic. This machine adopts AC motor control, stepless speed regulation, with the process of overload protection and fault alarm, the core of the screw and barrel of oil temperature oil circulation cooling, vacuum exhaust device and a quantitative feeding device.
Application Scenarios
The SJZ series conical twin screw extruder is a versatile plastics processing machine capable of producing finished products directly from raw polymer compounds. In PVC pipe production, the SJZ extruder with its conical twin screw configuration delivers the melt pressure and plasticating quality required for producing pipes ranging from small diameter plumbing tubes to large diameter drainage and conduit pipes. For PVC sheet and panel extrusion, the machine produces flat sheets used in construction, signage, and industrial lining applications. The extruder's ability to directly process PVC powder dry blends eliminates the pre-compounding step required with parallel twin screw extruders, simplifying the production workflow and reducing energy consumption. Profile extrusion lines use the SJZ to produce window frames, door frames, and decorative trim where the conical screw configuration's gentle plasticating action preserves the material's physical properties while delivering uniform melt for consistent cross-sectional dimensions.
