What are the reasons for cable defects? Reasons for cable defects In the long-term development of finished products such as cables, there are often some large or small defects in appearance, such as the surface of the components produced by the cable factory is not smooth, there are clay particles (previous rubber particles) or feet, Burns, abrasions, surface collapse, hemp streaks, etc. The following are five common factors that cause the appearance defects of rubber sheathed cables: 1. The length of the path between the front and back of the mold sleeve is too long or too short, the die opening is not smooth and the aperture is too large; the head, die opening or body Low temperature; small plasticity of rubber may cause the outer surface of the rubber sheathed cable to be rough. 2. The rubber used is not clean, and it contains scum; when it is scorched, the control is short, and the temperature of the body, head or die is too high; the green water of the rubber in the head does not flow for a long time. Smooth, there is a dead corner of the rubber material; the screw is not smooth, viscose, etc. may cause clay particles (early vulcanized rubber particles) or garbage piles on the surface of the rubber sheathed cable.
3. The large surface of the mold sleeve is very smooth, and there is no chamfer; it is believed that sometimes there is waste or cooked glue particles in the mold mouth; It may cause scratches and abrasions on the large surface of the rubber sheathed cable. 4. The hole diameter of the die sleeve is too large; the space between the outer strands of the conductive wire core and between the monofilaments is too large, and the outer diameter of the cable core is not uniform; the rubber material has small plasticity and poor viscosity; there is dirt in the rubber cutting; Low downforce may cause the surface of the rubber sheathed cable to be domed. 5. The diameter of the mold sleeve is too small, the rubber material is short enough to be drawn out, and the wire core will not be able to fill the seam; the conductive wire core or cable core jumper; the deviation of the mold is short, etc., which may cause hemp on the outside of the rubber sheathed cable. dapple.
