?0-?30 series PVC pipe extrusion line is mainly used in the manufacture of plastic PVC pipes with various diameters and wall thickness used in the industries such as agriculture and constructional plumbing, cable laying etc. This line is composed of conical twin-screw extruder, vacuum calibration tank, haul-off, cutter, stake and etc. The extruder and haul-off adopt imported AC frequency speed controller, vacuum pump and haul-off motor all adopt superior products. The haul-off method has two-claw, three-claw, four-claw, six-claw and etc. You may choose saw blade cutting type or planetary cutting type. It is additionally attached with length counter and intensifying device. This line is of reliable preformance and high production efficiency. Our company can also manufacture special pipe production lines, e.g. Spiral silencing pipe and core foaming pipe according to your requirements. The company successfully developed the PVC wood-plastic foamed plate production line. It not only has the appearance of natural wood, it overcome s short coming of wood, it has good processing ability which is similar as wood, it can be sawed and nailed. It can be finished with wood tools. Its fixed force is clearly better than normal wood material. It has physical characteristic, such as resistant to compression, resistance to impact and others which are similar as hard wood. Wood-plastic material and its products can be resistance strong acid and alkali, water proof, corrosion resistance, besides, germ cannot breed on it. It is not moth-eaten. It can be aging resistance, static electricity resistance, flame retardant. The product can be used in making building template, toy building blocks use the board, tray, package box, sleeper, outdoor floor, railings, garden chair and other outdoor facilities, indicating plate, circulating box, roof beam and others.
