the manufacturing method of wires and cables is completely different from that of most mechanical and electrical products. Mechanical and electrical products are usually assembled into parts by another part, and then assembled into a single product by multiple parts. The products are measured by the number of sets or pieces. The length of wires and cables is the basic unit of measurement. All wires and cables are made of wire and cable products by adding insulation, shielding, cabling, protective layers, etc. layer by layer on the periphery of the conductor from the conductor processing. The more complex the product structure is, the more layers are superimposed

I. process characteristics of wire and cable product manufacturing:

1. Large length continuous superposition combination production method

large length continuous superposition combination production method has an overall and controlling impact on wire and cable production, which involves and affects:

(1) production process and equipment layout

various equipment in the production workshop must be reasonably discharged according to the process flow required by the product, Make the semi-finished products of each stage flow in sequence. Equipment configuration should consider different production efficiency and balance the production capacity. Some equipment may have to be equipped with two or more to balance the production capacity of the production line. Therefore, the reasonable selection and combination of equipment and the layout of production site must be balanced and comprehensively considered according to products and production capacity

(2) production organization management

production organization management must be scientific, fair, thorough, correct, strict and meticulous, and the operator must implement the process requirements meticulously. Any problem in any link will affect the smoothness of the process flow and the quality and delivery of products. In particular, for multi-core cables, if the length of a pair or basic unit is short, or the quality is problematic, the whole cable will be insufficient, resulting in scrap. On the contrary, if the length of a unit is too long, it must be sawn to cause spreading

(3) quality management

the production mode of large-length continuous superposition and combination will affect the quality of the whole cable if a problem occurs at any link and instantaneously in the production process. The more quality defects occur in the inner layer, and the greater the losses caused by not finding and terminating production in time. Because the production of wires and cables is different from the assembled products, they can be disassembled, reassembled and replaced with another part; The quality problem of any part or process of wire and cable is almost irretrievable and irreparable to this cable. The subsequent treatment is very negative, either sawing or degrading, or scrapping the whole cable. It cannot be disassembled and reassembled

the quality management of wires and cables must run through the whole production process. The quality management inspection part should carry out patrol inspection of the whole production process, self inspection of operators, and mutual inspection of upper and lower processes, which is an important guarantee and means to ensure product quality and improve the economic benefits of enterprises
