1. Large length continuous stacking combined production method
The large-scale continuous superposition combined production mode has a global and control effect on the production of wire and cable, which involves and affects:
(1) Production process and equipment layout
All kinds of equipments in the production workshop must be discharged according to the technical process required by the product, so that the semi-finished products in each stage can be transferred in sequence. The equipment configuration should balance the production capacity in consideration of different production efficiencies. Some equipments may have to be configured 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 production volume.
(2) Production organization management
Production organization management must be scientific and reasonable, thorough and accurate, strict and meticulous, operators must be meticulously implemented according to the process requirements, any problem in one link will affect the smooth flow of the process, affecting 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 if there is a problem with the quality, the length of the entire cable will be insufficient, resulting in scrapping. Conversely, if a unit is too long, it must be sawed to cause waste.
(3) Quality management
The production method of continuous stacking of large lengths causes any problem in the production process and instantaneously, which will affect the quality of the whole cable. The more the quality defects occur in the inner layer, the greater the loss if the production is not discovered in time. Because the production of wire and cable is different from the assembled product, it can be disassembled and replaced; the quality of any part of the wire and cable or the process is almost irreparable and compensated for. After-the-fact processing is very negative, not short-cutting or downgrading, or scrapping the entire cable. It cannot be disassembled and reassembled.
