manufacturing process of the aluminum can body

The main manufacturing process of the aluminum can body is as follows: coil conveying → blanking, cup punching → stretching → tank forming → trimming → cleaning/drying → base color coating → drying → color printing → drying → internal spraying → drying → Reducing, flanging→palletizing

In the process flow, blanking, stretching, tank forming, trimming, diameter reduction, and flanging processes all require mold processing. Among them, the blanking, stretching, and tank forming processes and molds are the most critical, and their technological level and The level of mold design and manufacturing directly affects the quality and production cost of cans.
