Nuo Xing cable manufacturer briefs you on the process characteristics of wire and cable

August 20, 2021
Latest company case about Nuo Xing cable manufacturer briefs you on the process characteristics of wire and cable

The manufacturing of wires and cables is completely different from the production of most electromechanical products. Electromechanical products usually adopt the assembly of other parts into parts, and the assembly of multiple parts into a single product, and the products are measured by the number of units or pieces. Wire and cable are based on length as the basic unit of measurement. All wires and cables start from the processing of conductors, adding insulation, shielding, cabling, and sheathing layer by layer to the periphery of the conductor to make wire and cable products. The more complex the product structure, the more layers of overlap. Today, the editor will introduce its process characteristics to you!


1. There are many types of production processes and large material flow
Wire and cable manufacturing involves a wide range of processes, from smelting and pressure processing of non-ferrous metals, to chemical technologies such as plastics, rubber, and paint; textile technologies such as wrapping and weaving of fiber materials, to wrapping and metal strips of metal materials Longitudinal package, welding metal forming processing technology and so on.
Various materials used in wire and cable manufacturing not only have many types, varieties, and specifications, but also a large number. Therefore, the amount of various materials, spare amount, batch period and batch must be approved. At the same time, the decomposition, recycling, reuse, and waste disposal of waste products are an important part of management, and we should do a good job in material quota management and pay attention to conservation.
In the production of wires and cables, from the entry and exit 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 reasonable layout and dynamic management are necessary.


2. Large-length continuous stacking combined production method
The large-length continuous stacking combined production method has a global and controllable impact on the production of wires and cables, which involves and affects:
(1) Production organization management
The production organization and management must be scientific, reasonable, thorough, accurate, strict and meticulous. The operator must meticulously implement the process requirements. Any problem in any link will affect the smoothness of the process and affect the quality and delivery of the product. Especially for multi-core cables, if the length of a certain pair or basic unit is short, or there is a quality problem, the entire cable will be insufficient in length, resulting in scrap. Conversely, if the length of a certain unit is too long, it must be sawn to cause waste.
(2) Production process and equipment layout
Various equipment in the production workshop must be reasonably discharged according to the technological process required by the product, so that the semi-finished products in each stage can be circulated in sequence. The equipment configuration should consider the different production efficiency and balance the production capacity. Some equipment may have to be equipped with two or more units in order to balance the production capacity of the production line. Therefore, the reasonable combination of equipment and the layout of the production site must be balanced and comprehensively considered according to the product and production volume.
(3) Quality management
The quality management of wires and cables must run through the entire production process. The quality management inspection department shall conduct roving inspections of the entire production process, self-inspection of operators, and mutual inspection of upper and lower procedures. This is an important guarantee and means to ensure product quality and improve the economic efficiency of the enterprise. The production method of continuous superposition and combination of large length will cause any problem in any link of the production process to occur instantaneously, which will affect the quality of the entire cable. The more quality defects occur in the inner layer, and the production is not stopped in time, the greater the loss will be.


3. Many special equipment
Wire and cable manufacturing uses special production equipment with the characteristics of the industry to adapt to the structure and performance requirements of cable products, and to meet the requirements of large-length continuous and as high-speed production as possible, thus forming a special equipment series for cable manufacturing. Such as extruder series, wire drawing machine series, stranding machine series, wrapping 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 promote the production and development of new special equipment; in turn, the development of new special equipment has promoted the promotion and application of new processes. Such as wire drawing, annealing, extrusion tandem lines; physical foaming production lines and other special equipment, promote the development and improvement of wire and cable manufacturing technology, and improve the product quality and production efficiency of the cable.
