Plastic Twin Screw Extruder With CE Certificate , Twin Screw Extruder For Plastic Extrusion
Main characteristics of plastic twin screw extruder:
1. Optimized design and delicately made screw and barrel results in excellent plasticity.
2. Advanced electric control system, subsection failure alert, easily for trouble-shooting.
3. High-performance distribution system for torque decelaration enhanced the durability and easy for maintenance.
4. Highly efficient and super noise-free ventilators ensure quietly operating of equipment.
5. Perfect and accurate temperature control system ensures steady output.
Description of conical twin screw extruder:
1. Model SJZ series twin conical screw extruder is a kind of special equipment for extruding pvc powder.With different sorts of molds and auxiliary machines, it can produce all sorts of pvc plastic pipe material, profiled material, board material,sheet material, bar material and granulation.
2. The screw has applied oil cooling system.Barrel is cooled by special wind cooling system. The system has applied special conputer control. According to customer's requirement, most reasonable screw can be made so as to achieve best plasticity state and material quality.
3. The screw is made by high precision special digital screw miller, extruding property can be highly harmonized.It has firstly introduced advanced techique of producting screw with variable pitch and depth, so that the material can be more softly sheared and cut.
4. The distribution box is specially designed, pull force bearing is fully imported, and the drive life span can be prolonged, Ir can bear larger extruding pressure. The electrical system has mainly applied imported parts, it has multiple alarm system, and there are few problems which can be easily eliminated. The cooling sytem has applied special design, heat emission area is enlarged, the cooling is rapid, temperature control tolerance can be +-1degree.
