Mining lighting cable MYQ3 * 1.5-MYQ cableThe quality management of wires and cables must be integrated throughout the entire production process. The quality management inspection department should conduct patrol inspections, self inspections by operators, and mutual inspections between upper and lower processes throughout the entire production process. This is an important guarantee and means to ensure product quality and improve the economic efficiency of the enterprise.
1. There are multiple types of production processes and large material flow rates
The manufacturing of wires and cables involves a wide range of processes, from the melting and pressure processing of non-ferrous metals to chemical technologies such as plastics, rubber, and paint; The textile technology of wrapping and weaving fiber materials, to the wrapping of metal materials and the longitudinal wrapping and welding of metal strips, and so on.
The various materials used in the manufacturing of wires and cables are not only diverse in categories, varieties, and specifications, but also in large quantities. Therefore, the dosage, reserve quantity, batch cycle, and batch size of various materials must be determined. At the same time, the decomposition, recycling, reuse, and disposal of waste materials are important aspects of management, and material quota management and conservation work should be emphasized.
In the production of wires and cables, from the entry 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 reasonably laid out and dynamically managed.
2. Multiple devices
The manufacturing of wires and cables uses production equipment with the characteristics of the industry's technology to adapt to the structural and performance requirements of cable products, meet the requirements of long continuous and high-speed production, and thus form a series of equipment for cable manufacturing. Such as extruder series, wire drawing machine series, wire twisting machine series, winding machine series, etc.
The manufacturing process and equipment development of wires and cables are closely related and mutually promote each other. New process requirements promote the emergence and development of new equipment; On the other hand, the development of new equipment has also promoted the promotion and application of new processes. Such as wire drawing, annealing, extrusion series line; Equipment such as physical foaming production lines have promoted the development and improvement of wire and cable manufacturing processes, enhancing the product quality and production efficiency of cables.
