Process characteristics of bushing products manufacturing.
The large-scale continuous superposition combined production mode has a global and control effect on
the production of bushing, which involves and affects:
（1）Production process and equipment layout
All kinds of equipment 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 the product and production volume.
（2）Production organization management
The 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 Control
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, and the production is not discovered in time, the greater the loss. Because the production of bushing is different from the assembled product, it can be disassembled and replaced; the quality of any part of the bushing or the process is almost irreparable and compensated for. The after-the-fact processing is very negative, not short-cutting or downgrading, or scrapping the entire cable. It cannot be disassembled and reassembled.
The quality management of bushing must be consistent throughout the production process. The quality management inspection department shall conduct inspections of the entire production process, self-inspection of the operators, and mutual inspection of the upper and lower processes. This is an important guarantee and means to ensure product quality and improve the economic benefits of the enterprise.
