LB-PLC control High Capacity PVC Pipe Production Line

PVC pipe extruder machine is mainly used in the manufacturing of the UPVC and PVC pipes with various pipe diameters and wall thickness such as agricultural and constructional plumbing, water supply and drain etc.

This set is composed of conical twin-screw extrude, vacuum calibration tank, haul-off machine, cutter, stacker etc. The screw extruder and traction machine adopt imported AC frequency control device. The vacuum pump and traction motor both adopt advanced components. The haul-off machine has several models, such as two-claw, three-claw, four-claw, six-claw etc. It has visual blade and different cutting type.The unit is of reliable performance and high production efficiency.

Our machine can produce the PVC pipe with diameter from 16mm to 630mm

Products Details


1. Model SJZ series conical twin-screw extruder is a kind of special equipment for extruding PVC compound. With different kinds of molds and auxiliary machines, it can produce all sorts of PVC plastic pipe, profile, plate material, sheet material, bar material, and granulation.

2. The conical twin screws have applied the oil cooling system. Barrel is cooled by special wind cooling system.

3. The conical twin-screw extruder system has applied special computer control. According to customers requirements, most reasonable structure of conical twin-screw can be made so as to achieve the best plasticity performance and material quality.

4. The conical twin-screw is made by high precision special digital screw miller; extruding property can be highly harmonized. It has firstly introduced the advanced technique of producing screw with variable pitch and depth, so that the material can be more softly sheared and cut.

5. The distribution box is specially designed, pull force bearing is fully imported, and the drive life span can be prolonged. It can bear larger extruding pressure.

6. The electrical system has mainly applied imported parts, it has multiple alarm system, and there are few problems that can be easily eliminated. The cooling system has applied special design, heat emission area is enlarged, the cooling is rapid, and temperature control tolerance can be ± 1degree.

Product detail

Mixer With specific design of mixer, the self-friction of raw materials is reduced. It is conducive to the efficiency of energy utilization. The Vacuum suction load has low noisy and no-dust working situation.   Twin screw extruder machine The extruder are crafted with top brand components to ensure production stability, efficiency and machine durability. Our conical twin screw extruder design cater to the raw materials feature ensuring homogeneous mixture, better plastification and conveying efficiency.   Vacuum Calibration & Cooling The vacuum calibration tank adopt two chamber structure: the vacuum calibration and cooling parts. Both of vacuum tank and spraying cooling tank adopt stainless 304 steel. The excellent vacuum system ensures precise sizing for pipes.   Haul-off Unit The three caterpillar on the haul-off machine ensures produced pipe running stably and steady. The haul-off units can make tailored hauling model based on certain production requirement by adjusting the general control.   Cutting Unit The high accuracy encoder ensures a precise and stable cutting length. With PLC control system, it can be cut by manual operation according to the specific application.
