In the rubber cable production process, often appear the appearance of defects, such as smooth surface; surface of clinker particles (early vulcanized rubber particles) or impurities; wire and cable surface scratch, scratch; surface subsidence; surface twist grain. The following are five common causes of the appearance of the rubber cable:

1, the die sets the line is too long or too short, the die is not smooth and the aperture is too large; the nose, die or the body temperature is low; the rubber plastic small and so are likely to lead to the rubber cable surface is not smooth.

2, the supply of the rubber is not clean, containing impurities; rubber scorch time is too short; squeeze rubber body, the nose or mouth mold temperature is too high; head rubber flow is not smooth, rubber material stranded dead; screw is not smooth, viscose and so on have may lead to the emergence of clinker particles (early vulcanized rubber particles) or impurities cabtyre cable surface.

3. The die set is not smooth, without chamfering; impurities or glue particles blocking die; in the vulcanizing tube drag pipe abrasion; vulcanization pipe outlet sealing rubber washer smaller pore size were may lead to rubber cable surface scratches and abrasions.

4, a die sleeve aperture is too large; conductive wire core outer layer strands, single gap is too large, the outer diameter of the cable core is not uniform; rubber material plastic, viscosity is poor; rubber material impurities; to die from the small, small pressure and so on were possible cabtyre cable surface subsidence due to.

5, a die sleeve aperture is too small; rubber material extrusion problems, t
