Common causes of appearance defects in rubber cables

In the production process of rubber cable, there are often appearance defects, such as the surface is not smooth; the surface of clinker particles (early vulcanization of rubber particles) or impurities; wire and cable surface scratches, abrasions; the surface has collapsed; the surface of the sesame pattern, etc. 1. die sleeve bearer line is too long or too short, the die mouth is not smooth and too large an aperture; the head, the mouth of the mold or the machine temperature is low; the rubber material is small plasticity and so on may lead to rubber cable The surface is not smooth. 2. supply of rubber is not clean, containing impurities; rubber burning time is too short; extruding rubber body, head or mouth mold temperature is too high; head of the rubber flow is not smooth, there is rubber stagnation dead angle; screw is not smooth, sticky rubber, etc. may lead to the surface of the rubber cable clinker particles (early vulcanization of rubber particles) or impurities. 3. mold cover is not smooth, no chamfer; impurities or clinker particles blocking the mouth; In the vulcanization tube drag tube abrasion; vulcanization tube outlet seal rubber washer aperture is small, etc. may lead to rubber cable surface scratches, abrasions. 4. die sleeve aperture is too large; conductive core outer strands, monofilament gap between the large, uneven outer diameter of the cable core; rubber material plasticity is small, poor adhesion; rubber material in the impurities; die distance is small, small pressure, etc. may lead to rubber cable surface collapse. 5. die sleeve aperture diameter is too small; Rubber extrusion is not enough, the core gap is not filled; conductive core or cable core jumper; short distance to the mold and so on may lead to the surface of the rubber cable twist pattern.-6, on the Evergrande electronic products network platform related to the introduction and sales of products briefly: Evergrande electronic products network - a professional agent / production / sales of all kinds of {connectors | wiring harness | wire and cable products }; if you have a related [connectors | wiring harness | wire and cable products] procurement / purchasing needs or would like to buy / to understand which connectors | harness | wire and cable products we can provide solutions, please contact the following Division I business personnel; If you have related [connectors | wire harness | wire and cable products] sales / resources and promotion needs, please click on the "¡¡ Business Cooperation ←" with the person to discuss!
