The process of lid and bottom closure (bottom closure) of the can, the lid: opening-flashing-winding. Body: opening-pre-bending-cutting corners-forming-button bone-punching (bottom closure)-back cover. The bottom process is: cutting
If the can is hinged, then the lid and the body will each have one more process: hinge.
In the stamping process, the product loss is usually the biggest. Pay attention to whether the work operation is standardized, whether the product surface is scratched, whether there are batch seams in the winding line, and whether the button bones are fastened. The usual practice is to arrange before the mass production. The production of large samples is confirmed, and production is carried out according to the confirmed large samples, which can reduce a lot of trouble.
