gui chao cable news: five kinds of common reasons for appearance defects of rubber sheathed cable-非凡电子娱乐

in the production process of rubber sheathed cable, will often appear on the appearance of defects, such as the surface is not smooth; the surface of clinker particles (early vulcanized rubber particles) or impurities; cable surface scratch, scratch; surface subsidence; surface twist grain. the following are the five common reasons for the appearance of the defects of the cable in the cable network, which can be used as reference for the majority of rubber cable manufacturers:

first, the mold cover line is too long or too short, the mold mouth is not smooth and the aperture is too large; the nose, mold mouth or body temperature is low; rubber plastic small and so on are likely to lead to rubber cable surface is not smooth.

second, the supply of rubber is not clean, containing impurities; the scorch time is too short; extruding head or body, die temperature is too high; the rubber flow in die flow, rubber material retention dead; screw is not smooth, such as glue may lead rubber cable surface of clinker particles (early vulcanized rubber particles) or impurities.

third, the die sleeve is not smooth, no chamfer; impurities or glue particles by the die in the tube tube; vulcanized abrasion; vulcanized rubber gasket sealing pipe outlet aperture is too small may lead rubber surface scratch, scratch cable.

fourth, the die sleeve aperture is too large; the conductive wire core outer strands, monofilament gap is too large, the cable core diameter is not uniform; rubber plastic material, low viscosity; impurities rubber material; the mould distance is small, small pressure are likely to lead to the collapse of rubber cable surface.

fifth, the die sleeve aperture is too small; rubber extrusion, wire core slot fill; conductive wire or cable cores of short distance jumper; die may lead rubber cable lines appear on the surface of twist.
