pvc pipe extrusion production line for water supply/drainage
This PVC pipe extrusion line is mainly used to produce agricultural water supply/drainage pipes, architectural water supply/drainage pipes, cable laying pipes etc. This unit adopts advanced design concept to ensure the efficient extrusion of PVC powder, combined with the unique concept of plasticization screw design to ensure uniformity of plastic extrusion, high capacity production. This unit consists of : Conical twin screw extruder, pipe die head, vacuum calibrating tank, water spraying tank, haul off machine, cutting machine, and stacker etc.
Features:

1. Conical twin screw extruder: using the high efficient conical twin screws, specially designed for PVC power to ensure uniformed plasticization, high extrusion. Stable temperature controlling system can guarantee high quality pipe extrusion.
2. Mould: spiral type die head can not only ensure high speed extrusion, but also avoid the thermal decomposition of amorphous plastics and get high quality pipes. There is heating control system inside of the mould, high efficient, easy to extrude. Bronze calibrators can make the pipes fast calibrated and cooled.
3. Spraying and cooling tanks: Rapid vacuum calibrating system allows the hot extruded pipes to be cooled in a very short time and obtain the final pipe diameter. Automatic temperature control system, pressure regulator, and vacuum control valve greatly enhance the pipe sizing and cooling performance as well as the production speed.
4. Haul off machine: adopts caterpillar type, which includes two-claw types, three-claw types, four-claw types, six-claw types, eight -claw types, ten-claw types, twelve-claw types etc, suitable for different sizes of pipes. Haul off caterpillar blocks are made of abrasion resistant rubber material, which can make a high and stable hauling speed.
5. Cutting machine：precision machine cutter is able to make flat, straight cuts into pipes at high speed. A powerful suction device gathers up waste scraps after cutting, thereby making it easier for users to clean the cutter.
6. Pipe belling machine: automatic pipe belling machine comes with 2 heating ovens to ensure pipe belling quality and productivity.
