Products

First, wire and cable product manufacturing process characteristics:

1. Large length continuous superposition combination production method

Large length continuous superposition combination production mode, the impact on wire and cable production is global and controlled, 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 at each stage are transferred in succession. Equipment configuration to consider the production efficiency of different production capacity balance, some equipment may have to be configured two or more, in order to make the production capacity of the production line to be balanced. Therefore, the reasonable selection of equipment and the layout of production sites must be balanced according to the product and production capacity.

(2) Production organization and 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 of the problem, will affect the smooth process, affect the quality of the product and delivery. In particular, for multi-core cables, if the length of a certain pair or basic unit is short, or if there is a quality problem, the whole cable will not be long enough, resulting in scrapping. On the other hand, if a unit is too long, it must be sawed away to cause waste.

(3) Quality management

The production method of continuous superposition and combination of large lengths makes any link in the production process, and a problem occurs instantaneously, which will affect the quality of the entire cable. The more quality defects occur in the inner layer, and the production is not detected in time to terminate, the greater the loss caused. Because the production of wire and cable is different from assembled products, it can be disassembled and reassembled and replaced with 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.

The quality management of wire and cable must run through the entire production process. The quality management inspection department should tour the entire production process, the operator self-inspection, and the upper and lower processes mutual inspection, which is an important guarantee and means to ensure product quality and improve the economic efficiency of enterprises.

2. There are many kinds of production technology and large material flow

Wire and cable manufacturing involves a wide range of processes, from non-ferrous metal melting and pressure processing, to plastics, rubber, paint and other chemical technology; Textile technology, such as wrapping and weaving of fiber materials, to wrapping of metal materials and vertical wrapping of metal strips, welding metal forming processing technology and so on.

The various materials used in wire and cable manufacturing not only have many categories, varieties, specifications, but also a large number. Therefore, the amount of various materials, reserve amount, batch cycle and batch must be approved. At the same time, the decomposition of waste, 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, and it must be rationally distributed and dynamically managed.

3. Special equipment

Wire and cable manufacturing uses special production equipment with the characteristics of the industry process to adapt to the structure 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 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 is closely related to the development of special equipment and promotes each other. New process requirements to promote the generation and development of new special equipment; In turn, the development of new special equipment has improved the promotion and application of new processes. Such as wire drawing, annealing, extrusion series line; Special equipment such as physical foaming production line has promoted the development and improvement of wire and cable manufacturing process, and improved the product quality and production efficiency of cable.
