    Description

    Parameter Description
    Raw materials: PP HDPE PE PA POE PEK PVC (ABS, PMMA PVC screw: ABS POM PMMA HDPE PE general screw, gradient screw PP PA mutation screw bar extrusion equipment includes: extruder, machine head, cooling sizing die, insulation partition, Brakes, cutting machines, brackets, etc.
    The diameter of the extruder for the production of bars is generally φ45-90 mm. The size of the extruder is selected according to the diameter of the bar. The diameter of the extruder is preferably smaller than the diameter of the bar. For example, a φ45 mm extruder can be used to extrude bars with a diameter of 30-200 mm.

    The screw type of the extruder depends on the raw material. Gradient screw is used for PE, PVC, ABS, polycarbonate, polysulfone, polyphenylene ether, etc. Mutant screw is used for PP, PA, PU, polyoxymethylene, polychlorotrifluoroethylene, etc. The screw length-diameter ratio L / D = 20--28, compression ratio E = 2.5-3.5, the screw head is semicircular.

    In order to improve the plasticizing effect, a filter plate can be placed between the machine head and the screw. To filter impurities, 80-I50 mesh filter can be placed. However, when producing glass fiber reinforced rods, there is no need to put filter plates and filter screens.
