The manufacturing process of wires and cables is completely different from the production method of most electromechanical products. Mechanical and electrical products are usually assembled into components, multiple components are then assembled into a single product, and the product is measured in units or pieces. Wire and cable are measured in length as the basic unit of measurement. All wire and cable products are made by adding insulation, shielding, cabling, protective layers, etc. layer by layer on the periphery of the conductor, starting from the processing of the conductor. The more complex the product structure, the more layers it overlaps. Process characteristic 1: The production method of large length continuous superposition and combination has a global and controllable impact on the production of wires and cables. This involves and affects: (1) the production process and equipment layout. The various equipment in the production workshop must be reasonably discharged according to the product requirements, so that the semi-finished products in each stage can flow in sequence. Equipment configuration should consider the balance of production capacity based on different production efficiency. Some equipment may have to be configured with two or more units in order to balance the production capacity of the production line. Therefore, the reasonable selection and combination of equipment and the layout of production sites must be balanced and comprehensively considered based on products and production volume. (2) Production organization management must be scientific, reasonable, meticulous, accurate, and strict. Operators must strictly follow the process requirements. Any problem in any link will affect the smoothness of the process flow, affecting product quality and delivery. Especially for multi-core cables, if a pair or basic unit length is short or there is a quality issue, the entire cable will not be long enough, resulting in scrapping. On the contrary, if a certain unit is too long, it must be sawn off to cause waste. (3) The production method of quality management with large length continuous superposition combination can affect the quality of the entire cable if any problem occurs in any link or instant during the production process. The more quality defects occur in the inner layer and are not detected and terminated in a timely manner, the greater the losses caused. Because the production of wires and cables is different from assembled products, they can be disassembled, reassembled, and replaced with another component; The quality problem of any component or process of a wire or cable is almost irreparable and irreparable for this cable. The handling afterwards is very negative, either sawing it short or degrading it, or scrapping the entire cable. It cannot be disassembled and reassembled. The quality management of wires and cables must run through the entire production process. The quality management inspection department should conduct patrol inspections of the entire production process, self inspection of operators, and mutual inspection of upper and lower processes, which are important guarantees and means to ensure product quality and improve the economic benefits of the enterprise. 2. There are multiple production processes with high material flow, and the manufacturing of wires and cables involves a wide range of processes, from the melting and pressure processing of non-ferrous metals to chemical technologies such as plastics, rubber, and paint; The textile technology of fiber material wrapping and weaving, as well as the metal material wrapping and longitudinal wrapping of metal strips, as well as the metal forming processing technology of welding, etc. The various materials used in the manufacturing of wires and cables are not only of various types, varieties, specifications, but also in large quantities. Therefore, the dosage, reserve quantity, batch cycle, and batch size of various materials must be verified. At the same time, as an important part of management, the decomposition, recycling, reuse, and waste disposal of waste products should be well managed, with a focus on material quota management and conservation. In the production of wires and cables, from the entry and storage of raw materials and various auxiliary materials, the circulation of semi-finished products in various processes to the storage and delivery of products, the material flow is large, and it must be reasonably arranged and dynamically managed. 3. Specialized equipment for the manufacturing of multiple wires and cables uses specialized production equipment with the characteristics of the industry's processes to adapt to the structural and performance requirements of cable products, meet the requirements of large length continuous and high-speed production as much as possible, thus forming a series of specialized equipment for cable manufacturing. Such as extrusion machine series, wire drawing machine series, stranding machine series, wrapping machine series, etc. The manufacturing process of wires and cables is closely related to the development of specialized equipment, promoting each other. New process requirements promote the emergence and development of new specialized equipment; On the contrary, the development of new specialized equipment has promoted the promotion and application of new processes. Such as wire drawing, annealing, and extrusion series lines; Special equipment such as physical foaming production lines have promoted the development and improvement of wire and cable manufacturing processes, improving the product quality and production efficiency of cables. Power cables and power cables. The main process of wire and cable production is through three processes: drawing, twisting, and wrapping. The more complex the model and specification, the higher the repeatability. 1. In metal pressure processing, the technical processing method of metal drawing is to force the metal through the mold (pressing wheel) under external force, compress the cross-sectional area of the metal, and obtain the required cross-sectional area shape and size. The drawing process is divided into single wire drawing and twisted drawing. 2. Twisting is to improve the flexibility and integrity of wires and cables by interweaving two or more single wires in the specified direction. The twisting process includes conductor twisting, cable forming, weaving, steel wire armor, and winding. 3. According to different performance requirements for wires and cables, special equipment is used to coat different materials on the outside of the conductor. Packaging process includes: A. Extrusion packaging: materials such as rubber, plastic, lead, aluminum, etc. B. Vertical packaging: rubber, wrinkled aluminum strip material. C. Wrapping: Ribbon paper tape, mica tape, alkali free glass fiber tape, non-woven fabric, plastic tape, etc., and linear cotton yarn, silk and other fiber materials. D. Dip coating: insulation paint, asphalt, etc
