SJSZ65 series conical twin-screw extruder is mainly used for extruding soft and hard PVC, polyethylene and other thermoplastics. It cooperates with corresponding auxiliary machines (including molding heads) to process various plastic products, such as Film, tube, plate, wire, tape, cable insulation layer and hollow products, etc., can also be used for granulation.
Structure and function of SJSZ65 Plastic twin screw barrel extruder making machine:
SJSZ65 series conical twin-screw extruder is equipped with a discharge device to improve product quality.
SJSZ65 series conical twin-screw extruder screw is conical, so that the melt can be extruded at lower temperature. 38CrMoA1A, nitrided, surface hardness: HV>=900, nitrided layer depth: 0.5-0.8mm, double-alloy welding is used on the screw surface to improve the service life of the screw. The easy-to-wear part of the material port is made of imported alloy steel. After special treatment, it can effectively improve the usability of the barrel and improve the service life.
The screw core of plastic extruder machine is equipped with an automatic circulation cooling adjustment system, which improves the efficiency and is reliable in use.
The SJSZ65 series conical twin-screw extruder is equipped with a resistance heater on the barrel, and the heat transfer is fast and uniform.
SJSZ65 series conical twin-screw extruder adopts variable frequency stepless speed regulation, stable speed and convenient speed regulation.
SJSZ65 series conical twin-screw extruder adopts Japanese OMRON temperature control table, and the temperature control precision is high.
SJSZ65 series conical twin-screw extruder is equipped with an overcurrent holding device, which is reliable in protection.
