In order to meet market demands, JWSBL-300/600/800/1000/1200 equip concial twin-screw extruder and born to produce FRPP and PVC DWC, has the following characteristics :

1. Overall energy consumption of the production line is low, the conveyor efficiency of the concial twin screw extruder is higher than the single screw extruder and the installed power is less than the single screw extruder.
2. The power material can be extrusion directly, use material add calcium powder formula, reduce the cost and improve the pipe ring stiffness.
3. The extruder has a vacuum device to overcome the problem of air bubbles inside and outside the pipe due to the moisture content in the raw material.

Other Pipe Line Assisting Parts :

• Screw and barrel : Use China’s best screw brand established in 1978 which has 40 years professional experience in production of screw barrels. An effective guarantee of product quality. Offer single-screw, twin-screw barrels also has special customized designs.
• Online Pipe Weight Metering And Monitoring System : Gravity metering equipment is used in the extrusion process which can save raw material consumption to the greatest extent and reduce boot waste. The control accuracy is less than ± 0.3%.
• Pipe Socketing Machine : This machine can be used for the belling of PVC/PP solid wall pipe, double-wall corrugated pipe. The belling mould adopts hydraulic driving. The range is Φ20-Φ800.
• Mixers : Adopts PLC control. It is mainly applied to the process of ingredients, mixing, coloring, drying and devolatilization of various resins such as polyvinyl chloride.
• Crusher : Shredding scraps during the production of reclaimed pipes and unconventional products produced during trial production. There are crushers with different uses and specifications to choose form.
