Reasons for Appearance Defect of Rubber Sleeve Cable

Release time:

2023-07-21

The bearing line of the die sleeve is too long or too short, the die opening is not smooth and the aperture is too large; The temperature of the machine head, die opening or body is low; Small rubber plasticity may cause the surface of the rubber sleeve cable to be not smooth.

Reasons for Appearance Defect of Rubber Sleeve Cable

1. The bearing line of the die sleeve is too long or too short, the die opening is not smooth and the aperture is too large; The temperature of the machine head, die or fuselage is low; Small rubber plasticity may cause the surface of rubber-sheathed cable to be not smooth.

2, the supplied rubber is not clean and contains impurities; The scorch time of the rubber material is too short; The temperature of the extruded rubber body, head or die is too high; The flow of rubber in the head is not smooth, and there are dead corners where rubber stays. The screw is not smooth, and the glue, etc. may cause clinker particles (early vulcanized rubber particles) or impurities on the surface of the rubber cable.

3, the mold sleeve is not smooth and has no chamfer; Impurities or cooked rubber particles block the die; Drag the tube in the vulcanization tube for scratches; The small aperture of the rubber gasket sealed at the outlet of the vulcanization tube may cause scratches and abrasions on the surface of the rubber sleeve cable.

4, the aperture of the mold sleeve is too large; The gap between the outer strands and monofilaments of the conductive core is large, and the outer diameter of the cable core is uneven. Rubber has small plasticity and poor viscosity. Impurities in rubber; Small distance to die and small pressure may lead to surface collapse of rubber-sheathed cable.

5, the aperture of the mold sleeve is too small; Insufficient extrusion of rubber material and filling of core gaps; Conductive core or cable core jumper; Short distance to die may lead to hemp pattern on the surface of rubber-sheathed cable.
