Hello, this is renhotec group. Let me share some professional knowledge about wire and cable industry, so that you can have a better understanding of wire and cable purchase
At present, the manufacturing method of all wires and cables is to slowly process cables into conductors, followed by specific structural operations. All structures are very complex. However, the more complex the structure is, the more layers will be superimposed. Before the cable is processed into a conductor, the wire and cable products are formed by adding insulation, shielding, molding, sheath, etc. on the outside of the conductor layer by layer. The basic unit of measurement of wire and cable is length. However, the product quality of cables must be strictly guaranteed.
The categories of process production need to be familiar with many processes, and the process classification involved is also very extensive in the production, from smelting and pressure processing of non-ferrous metals to chemical technologies such as plastics, rubber and paint; Textile technology such as wrapping and weaving of fiber materials, wrapping of metal materials, longitudinal wrapping of metal strip, metal forming and processing technology of welding, etc. The materials used are not only of various types, varieties and specifications, but also of large quantities. Therefore, the consumption, reserve consumption, batch cycle and batch of various materials must be verified. At the same time, the decomposition, recycling, reuse and waste disposal of waste products, as an important part of management, do a good job in material quota management and pay attention to saving. In the production of wire and cable, from the import and export and storage of raw materials and various auxiliary materials, the circulation of semi-finished products in each process to the storage and delivery of products, the material flow is large, so it must be reasonably arranged and dynamically managed. Special equipment multi wire and cable manufacturing uses special production equipment with the process characteristics of the industry to meet the structure and performance requirements of cable products and meet the requirements of large-length continuous and high-speed production as much as possible, thus forming a series of special equipment for cable manufacturing. Such as extruder series, drawing machine series, stranding machine series, wrapping machine series, etc.
The process manufacturing of wire and cable is related to the new equipment. More wire and cable manufacturing uses special production equipment with the process characteristics of the industry. It is necessary to promote the generation and development of new process equipment, so as to meet the structural and performance requirements of cable products and meet the requirements of large-scale continuous and high-speed production as much as possible, so as to form a series of special equipment for cable manufacturing. Such as extruder series, drawing machine series, stranding machine series, wrapping machine series, etc; On the contrary, the development of new special equipment has improved and promoted the popularization and application of new technology. Such as wire drawing, annealing, extrusion series line; Special equipment such as physical foaming production line promotes the development and improvement of wire and cable manufacturing process, and improves the product quality and production efficiency of cable. The equipment configuration should consider the different production efficiency to balance the production capacity. Some equipment may have to be equipped with two or more to balance the production capacity of the production line. The layout of the production site and the reasonable selection and combination of relevant equipment must be measured and considered according to the products and production capacity. All product process equipment must reasonably discharge the process flow of various production requirements, so that the semi-finished products in each stage can be transferred in sequence.
Because the quality management of many wires and cables is not appropriate in the way of production management, once any problem occurs in any process of production, it will affect the quality of cables. The cable cannot be disassembled and reassembled, but the whole cable is scrapped. The quality of the cable is strictly enforced, and the quality of the product must be guaranteed. The careful and meticulous management of the operator will affect the smooth and scientific production process, and any problem must be strictly implemented according to the scientific process requirements. Especially for multi-core cables, if the length of a pair or basic unit is short, or there is a quality problem, the length of the whole cable will be insufficient, resulting in scrapping. On the contrary, if the length of a unit is too long, it must be sawn away, resulting in waste.
