This extrusion line is made up of conical twin screw extruder, vacuum calibrator, hauler, cutter and stacker. AC frequency conversion speed regulators are applied in extruder and hauler. Components of high quality are equipped on vacuum pump and hauling off motor. There are two-claw, three-claw, four-claw, six-claw and eight-claw hauler to be chosen from. Saw cutter or planet cutter is optional which is equipped with length meter and incrassation devices. The whole line works stably and efficiently. We can allocate exclusive devices to produce inner spiral pipes, muffling hollow pipes, hollow spiral pipes and core layer foam pipes. The planet cutter is controlled by digital computer which is convenient to operate.
