Cable manufacturing process

1. Process characteristics of wire and cable product manufacturing:

1. Large length continuous superposition combination production mode

The large length continuous superposition combined production mode has a global and controlling influence on the production of wire and cable, which involves and affects:

(1) Production process and equipment layout

All kinds of equipment in the production workshop must be reasonably discharged according to the product requirements of the process flow, so that the semi-finished products of each stage, in turn. Equipment configuration should consider different production efficiency to balance the production capacity, some equipment may have to be configured with two or more sets, so that the production capacity of the production line can be balanced. Therefore, the reasonable selection of equipment and the layout of the production site must be balanced according to the product and production capacity.

(2) Production organization management

Production organization and management must be scientific and reasonable, thorough and accurate, strict and meticulous, the operator must be meticulous in accordance with the process requirements, any link problems, will affect the smooth process, affect the quality of products and delivery. Especially for multi-core cables, if the length of a cable pair or basic unit is short, or the quality problems occur, the whole cable will not be long enough, resulting in scrap. Conversely, if a unit is too long, it must be sawed away for waste.

(3) Quality management

The large length continuous superposition combination production mode, so that any link in the production process, instantaneous problems will affect the quality of the whole cable. The more quality defects occur in the inner layer and production is not detected and terminated in time, the greater the loss will be caused. Because the production of wire and cable is different from assembled products, you can disassemble and reassemble and replace another part; The quality problems of any part or process of wire and cable are almost irreparable and irreparable for this cable. Afterwards, the treatment is very negative, either sawing or degrading, or scrapping the entire cable. It can't be taken apart and reassembled.

Wire and cable quality management must run through the entire production process. Quality management inspection department to the whole production process inspection tour, operator self-inspection, upper and lower process mutual inspection, which is to ensure the quality of products, improve the enterprise economic benefits of an important guarantee and means.

2. Multiple production processes and large material flow

Wire and cable manufacturing involves a wide range of processes, from non-ferrous metal smelting and pressure processing, to plastics, rubber, paint and other chemical technology; Fiber material wrapping, weaving and other textile technology, to metal material wrapping and metal strip longitudinal wrapping, welding metal forming processing technology and so on.

The various materials used in the manufacture of wire and cable are not only of many types, varieties and specifications, but also in large quantities. Therefore, the amount of various materials, reserve amount, batch cycle and batch must be approved. At the same time, the waste decomposition, recycling, reuse and waste treatment, as an important content of management, do a good job of material quota management, pay attention to saving work.

In the production of wire and cable, from the entry and exit and storage of raw materials and various auxiliary materials, the flow of semi-finished products in each process to the storage and delivery of products, the material flow is large, must be reasonable layout and dynamic management.

3. Many special equipment

Wire and cable manufacturing uses special production equipment with the characteristics of the industry process, in order to adapt to the structure and performance requirements of cable products, to meet the requirements of large length continuous and as high speed as possible production, thus forming a series of special equipment for cable manufacturing. Such as extruder series, drawing machine series, stranding machine series, winding machine series, etc.

The manufacturing process of wire and cable and the development of special equipment are closely related and promote each other. New process requirements to promote the production and development of new special equipment; In turn, the development of new special equipment, and promote the promotion of new technology and application. Such as wire drawing, annealing, extrusion series line; Physical foaming production line and other special equipment, promote the development and improvement of wire and cable manufacturing technology, improve the cable product quality and production efficiency.
