UPVC/PVC Pipe Extrusion Line/ Plastic Tube Extruder

‍‍

Features：

PVC pipe making machine /PVC pipe extrusion production line/ is mainly used in the manufacture of the UPVC and PVC pipes with various pipe diameter and wall thickness, such as the agricultural and constructional plumbing, water supply and water drainage, electric conduit pipe etc.

Our extrusion line can produce the PVC pipe with diameter from 16mm to 630mm.

Process flow：

‍Feeder  →   Mixer    →    Feeder    →    Extruder     →    Mould    →    Vacuum tank    →    Haul-off   →  Printer  →   Cutting    →    Stacker

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.

Working principle：

After mixing raw material with other additives, the mixed powder will be fed into the extruder by spring feeder or vacuum feeder, after extrusion, the soft hot pipes will be produced by mould, then it goes into the vacuum calibration tank. The vacuum calibration tank's function to keep the pipe's shape and cool it, the vacuum calibration tank is mainly imposed of one or several water pump, one or several vacuum pump, and several rows of spraying nozzle. after cooling and forming shape, the pipes will be pulled to next machine--haul off machine, haul off machine's mainly function is to keep the pipes forward, there are two caterpillars, three caterpillars, even to eight caterpillars for different diameter pipes. After haul off machine, the next machine is cutter, its function is to cut the pipes based on required length. there are also several type of cutting way, one is cutter type, another is planetary type cutter, and we also have no-dust type cutter, they are used for different type of pipes. At last, you can get good quality PVC pipes by our extrusion line.
