Analysis of manufacturing technology of wire and cable

　　Overview of wire and cable manufacturing process The manufacturing method of wire and cable is completely different from that of most electromechanical products. Mechanical and electrical products are usually assembled into parts and multiple parts into a single product. The product is measured by the number of units or pieces. The basic unit of measurement is the length of wires and cables. All wires and cables are made of wires and cables by adding insulation, shielding, cabling, protective layer, etc. on the periphery of the conductor layer by layer, starting from the processing of the conductor. The more complex the product structure is, the more layers are superimposed.

　　Wire and cable

　　1、 Process characteristics of wire and cable manufacturing:

　　1. Large-length continuous superposition combination production mode Large-length continuous superposition combination production mode has a global and controlled impact on wire and cable production.

　　This involves and affects:

　　(1) Production process flow and equipment layout The various equipment in the production workshop must be reasonably discharged according to the process flow required by the product, so that the semi-finished products at each stage can be circulated in sequence.

　　(2) Production organization management The production organization management must be scientific, reasonable, thorough, accurate, strict and meticulous. The operator must strictly follow the process requirements. Any problem in any link will affect the smoothness of the process flow and the quality and delivery of products.

　　(3) The production mode of large length continuous superposition and combination of quality management will affect the quality of the whole cable if any problem occurs in any link and instantaneously in the production process. The more quality defects occur in the inner layer and the production is not found and terminated in time, the greater the loss will be caused.

　　2. The manufacturing of wires and cables involves a wide range of processes, from smelting and pressure processing of non-ferrous metals to chemical technologies such as plastics, rubber, paint, etc; Textile technology such as wrapping and weaving of fiber materials, to wrapping of metal materials, longitudinal wrapping of metal strips, and metal forming process of welding, etc. The various materials used in wire and cable manufacturing are not only of many types, varieties and specifications, but also in large quantities.

　　3. Special equipment for wire and cable manufacturing uses special production equipment with process characteristics of the industry to adapt to the structure and performance requirements of cable products and meet the requirements of large length continuous and high-speed production as far as possible, thus forming a series of special equipment for cable manufacturing. Such as extrusion machine series, drawing machine series, stranding machine series, wrapping machine series, etc. The manufacturing process of wires and cables and the development of special equipment are closely related and promote each other.
