Description

Raw material: PP HDPE PE PA (ABS, PMMA PVC

Screw: ABS POM PMMA HDPE PE universal screw, gradient screw PP PA mutation screw

Bar extrusion equipment includes: extruder, head, cooling sizing die, thermal insulation partition, braking device, cutting machine, bracket and so on.

The diameter of the extruder used to produce the bar is generally φ45–90 mm. Selecting the size of the extruder is mainly based on the diameter of the rod. It is best that the diameter of the extruder is smaller than the diameter of the rod, and the operation of extruding the rod is easier. For example, using a φ45 mm extruder can extrude rods with a diameter of 30-200 mm.

Extruder screw type depends on the raw material. Gradual screw is used for PE, PVC, ABS, polycarbonate, polysulfone, polyphenylene ether, etc. Mutation screw is used for PP, PA, PU, polyformaldehyde, polytrifluorochloroethylene, etc. The screw L / D ratio is 20–28, the compression ratio is E = 2.5-3.5, and 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 remove impurities, a 80-I50 mesh filter can be placed. However, when producing glass fiber reinforced rods, there is no need to put filter plates and filters.
