Details about products
KR-series multi-function extrusion line for PVC pipe is developed based on the foreign technique and actual local situation, which is highly automatically controlled and is ranking at the leading position domestically.
PVC pipe has been holding a big share in the market, which is used as pressured pipe and non-pressure water discharging pipes, including fresh water supply, low pressure pipe water discharging pipe for building, drainage pipe and cable protection. We supply conical twin screw high-efficiency extruder (SJZ45/90---SJZ100/200) and parallel conical twin screw extruder (SJP75/26----SJP130/26-33), the output rate reaches up to 1200KG/H. To realize high amount of additive calcium(CaCO3), the KR-series screw and barrel are made with special material BEXALIT, which is greatly wear-resistant and its bimetallic material, so its service life is very long. The dovetail-shaped spider structural mould is available for PVC extrusion, all kinds of PVC ranging among Ø16-Ø800mm can be produced if going with corresponding auxiliary device and belling machinery.
 
Equipment characteristics
1. Optimized high-efficiency conical twin screw extruder and parallel twin screw extruder are suitable for producing PVC pipes with different prescriptions of raw material and stocks. Advantages: compact structure, even melting and mixing, stable quality, wide scope of applicability, long service life, and maintenance-free temperature control system of screw , low compression ratio, low rotation speed, high output, high rated torque, low maintenance cost, excellent performance.
2. The special-purpose forced feeding system matched with twin screw keeps the PVC extrusion stable.
3. Strong and durable hard-surface drive system makes sure the stable extrusion output and good quality.
4. Temperature control system guarantees stable output when different screws are at different speed.
5. 3 layers of the special-purpose composite pipes can be satisfactorily handled.
6. Automatic closed-loop control is realized via smart modular C4 control system.
7. For those customers who request screw & barrel and gearbox critically, the European imported products would be the good choices.
8. Dovetail-shaped spider structural PVC mould can minimize joint line of the melted material to ensure the good quality. Spherical-surface joint is adopted for the bush and pin, which is easy adjusted, quick, material saving and time saving. Ceramic heater or cast aluminum heater can serve for longer time. Dovetail-shaped design, proper compression ration and material stay time make the pipe surface smooth.
9. According to different process, induction chrome plated stainless steel or wear-resistant copper diameter collar can be used.
10. Vacuum calibrator tank is built based on high-efficiency dual chamber calibration technique and ultra-long quick cooling technique; quick vacuum adjustment system ensures the vacuum degree and quick calibration of PVC.
11. Rain curtain type spraying tank is built with optimized spraying positioning and piping, which guarantees the strong, quick and equal cooling for large diameter pipe.
12. The drive is the 3-8 caterpillar driving device, all the caterpillar bands are driven separately by AC motors and controlled by digital controllers, which is very important for accurate speed adjustment and removes the possibility of slipping due to unequal driving force distribution, therefore, the stability of extrusion is gained.
13. The hydraulic planetary cutter cuts the pipe , one is rotary cutting, another is synchronizing cutting with bevel angle. The cutter is hydraulically controlled, and it has the function of length tracking, which is monitored by PLC.
14. KR-series automatic double-furnace heating belling machine with vacuum fixed diameter are good choices, which can guarantee the quality and raise the efficiency of belling machine.
