Plastic Conical Twin Screw Extruder PVC For Pipe Profile Sheet Extrusion

Plastic PVC Conical Twin Screw Extruder for Pipe Profile Sheet Extrusion pvc pipe molding machine
 
Plastic PVC Conical Twin Screw Extruder Application Area
1. The Twin Screw Extruder are mainly used for the processing of the soft/hard PVC pipe, PVC foaming board, PVC sheet, PVC Profile, PVC Trunk, PVC Roof tile, PVC Pelletizing and other polyolefin products, especially the direct processing of the plastic/powder materials.
2. Twin Screw Extruder is applicant for PVC powder material, with different mould and downstream equipment; the plastic extruder can produce pipe, profile, plate&sheet, and pelletizing.
3. The extruder features in good plastic extrusion, good plasticization, even melting, high output capacity, wide application and reliable stability, specially designed gearbox and distributor and reinforced thrust bearing realize large transmission torque and long operation time.
4. Electrical control system: Siemens PLC/PCC auto control system or RKC temperature control, and ABB Invert/transducer, Siemens contactor, and several alarm system
 
Characteristics and spare parts of the extrusion machine
The gearbox
1. New-style project of parallel three-axises driving makes the convey axis, convey chain, decelerate and the torque assignment get together, which keep it compact, and the key bearings are imported.
2. The select material of drive components is dainty, including super intension alloy cementiteing steel, cementiting and quenching, gear grinding technics, strengthening of tooth face. So they can ensure high torque, high precision and low noise.
3. Soakage and coerce lubrication integrate smoothly. When the hydraulic circuit is over pressed, it alarms.
 
The feeding system
Metering feeders are equipped with single screw, twin screw, hollow screw, forced-feeding, side feeding, liquid-adding
system,etc.
 
Screw
1. The screw elements and then kneading blocks are designed accurately, by precise processed, agile combination, with interchangeability, which can fulfill efficient self-cleaning, transmission, compounding, pressure-forming.
2. The screw material is made of high tool steel 38CrMoALA or W6Mo5Cr4V2 by special heat-treament.
 
The barrel
1. Eurostyle rectangle barrel, reflux refrigeration is optimized and disposed, which makes temperature difference in C areas smaller.
2. According to the material and special techinics demands, the material of cylinder can use high quality nitrided steel, corrosion proof or antifriction with corresponding process.
The heater
Innovated design of heater tightened style insures high efficiency of heat transfer and high longervity of heater.
