This PVC pipe extrusion line mainly consists of conical twin screw extruder, PVC pipe molds, vacuum calibrating water tank, water spraying cooling tank, haul-off machine, cutting machine and overturning bracket. 
Conical twin-screw extruder: It equipped with forced fixed-quantity material feeding system, automatic temperature control system, vacuum exhaust system and automatic speed control system. This structure assures accurate controlling for the material temperature, plasticization stability and greatly improving production speed. The main motor is direct convertor or frequency convertor. Motor output torque stability which can achieve step-less speed regulation. 
PVC extruding molds: Material is high quality 40Cr. Molds surface is dealt with polishing and chrome plating. it adopts the structure of multiple head spiral. The melt has low pressure. Extruding at high quantity, the die head still maintain low temperature.
Vacuum calibrating water tank: The material of body is high hardness and good quality stainless steel board. It is high-pressure resistance, corrosion-resistance and two-stage for large diameter pipe. Stainless steel float adjusts water level and the structure simple and practical. Electricity controls water temperature. The nozzle material is ABS engineering plastic. The frame of the machine can be adjusted three dimensions. The moving from front to back adopt cycloid reducer drive and up & down and left & right adopt screw adjustment.
Water spray cooling tank: The body is made of stainless steel and the shade is transparent soft PVC curtain. Stainless steel float adjusts water level and electricity controls water temperature. The nozzle material is ABS engineering plastic. The frame of the machine can be adjusted up and down. There is roller in the tank. 
Haul-off machine: It adopts frequency conversion approach. Every traction frame transfers with chain which ensures every track moving simultaneously. It is pneumatic flexibility clamping. The bearing has special structure which can effectively reduce the installation error. The machine has V type high friction coefficient rubber. 
Cutting machine: It is planetary cutting for large diameter. The blade takes rotation and cutting part and inserting blade part take revolution. It has angle cutting structure, pneumatic aluminum half clamping and cleaning device.
Control system: We can offer SIEMENS PLC controlling system which is intelligent controlling system. Also we can offer ordinary controlling system which use Siemens electrical parts, Omron temperature controller. Operation is simple.
Vacuum pump and tractor adopts high-quality products. Tractors can be divided into up and down pedrail, three-claw, four-claw, six-claw, etc. in terms of thickness and diameter of the pipe. The cutter has two modes of cutting such as blade and planet type. Additionally, metering device is equipped. The property of the production line is reliable and the output is high.
