(1) button batteries shrapnel must satisfy the product use and technical performance, and can be convenient for assembly and replacement.
2 button battery shell must be beneficial to improve the utilization rate of metal materials, as far as possible, reducing the consumption of materials.
(3) when the button batteries shrapnel stamping number have to simplify mould structure, simplify the process, which is the least, the most simple stamping process to complete the entire parts processing, reduce processing with other methods, is helpful for stamping operation, is advantageous for the organization to realize mechanization and automation production, in order to improve labor productivity.
(4) button batteries shrapnel, in can ensure normal use, promotes the exchange of products, reduce scrap, guarantee the stability of product quality.
5] button battery shell design, should be conducive to try to use the existing equipment, process equipment and technological process for machining, and is helpful to extend the service life of die.
