Reasons for defects in the appearance of rubber cables?

I. Rubber cable appearance of defects in the reasons? 1. It may be because the die set of the bearer line is too long or too short caused by the production of rubber cables, or the production of rubber cable mold mouth is not smooth enough or the production of wire equipment caliber is too large caused by the second is the head of the equipment, the mold mouth or the equipment is too low temperature of the machine body; or due to the rubber cable raw materials, rubber plastic is too small, may lead to rubber cables Surface is not smooth situation occurs. 2. It is possible that the production of rubber cable raw material rubber supply is not clean enough, the internal impurities; or rubber material in the scorching combustion, too short a time, so that the rubber raw material burning is not uniform; extrusion of rubber body, head or mouth mold temperature is too high; or due to the head of the equipment inside the flow of the rubber material is not smooth enough, resulting in stagnation, The appearance of dead ends; 3. may be the production of rubber cable die sleeve is not smooth enough, not chamfering caused; or in the production process there are impurities or cooked rubber particles blocking the equipment mold mouth caused; or because of the vulcanization of the pipe inside the towing tube there are abrasions, vulcanization of the exit of the tube sealing the rubber washer aperture is too small is also very likely to cause the surface of the rubber cable scratches, abrasions. 4. May cause defects in the rubber cable may be caused by the aperture of the die set equipment is too small; rubber material extrusion is not enough, the core gap is not filled; or due to the conductive core or the cable core has a jumper case; short distance to the mold, etc. may lead to the surface of the rubber cable twist pattern. 5. may be too large an aperture of the die set of rubber cable caused by defects in the appearance of the rubber cable; or rubber-plastic material adhesion is too small, adhesion is too Poorly caused; there may also be impurities in the rubber raw materials.
