PVC multi layers co-extrusion pipe production line machine is used to produce three layers or four layers PVC pipe. Main extruder adopts two or three sets conical twin screw extruder, different capacity extruder for option.
Equipment Composition:
Conical Twin Screw Extruder (2 or 3 sets) + Co-extrusion multi layers PVC pipe mould + Vacuum calibration tank + Caterpillar type Hauler + Dust-free Cutter + Stacker
Advantage:
2 or 3 sets of conical twin screw extruder machine are used to co-extrusion three-layer or four-layer PVC pipes. The pipe sandwich layer is made of high calcium PVC or PVC foaming material.
● The extruder adopts super wear-resistant alloy screw barrel, the twin-screw feeder is evenly fed, and the powder is not bridged;
● The optimized design of PVC three-layer mold, the runner is chrome plated and highly polished, wear-resistant and corrosion-resistant; with the special sizing sleeve, the production speed is fast and the pipe quality is good;
● The cutter adopts rotary clamping device, which adapts to different pipe diameters and avoids the trouble of frequent replacement of clamps. Equipped with a new adjustable floating chamfering mechanism, which can be adjusted according to pipe diameter and wall thickness. Adjust the chamfering size, cut and chamfering in one step. Closed vacuum device, better chip suction effect.

Extrusion Line Details:
Application:
PVC composite pipe is a new type of composite drainage pipe. The pipe is a three-layer co-extrusion composite drain pipe, the inner and outer walls of which are hard PVC, to ensure the enough strength and other physical properties of the pipe. The middle layer is made of special formula PVC, the relative density is 0.7-0.9g/cm3, and the structure of the layer is micro closed pore. This kind of special structure cleverly uses the principle of type I structure in mechanics of materials. It can be observed that the intermediate interlayer is soft colloid, which not only has all the advantages of PVC (empty wall) pipe, but also has the advantages of sound insulation, heat insulation, shock resistance, impact resistance, light weight and low price over the solid wall pipe.
