What is the process flow of canning machine?

The production process of the canning machine is a precise and complex process. During the production process, all empty cans are painted inside to improve the corrosion resistance of metal packaging iron cans. At the same time, the electrochemical action of the metal is used to dissolve a small amount of iron in the metal iron box. The stamping forming of cans refers to the use of the punch of the punch press to punch the flat plate into the cylindrical mold to deform the flat metal plate into a round iron can. The diameter of the iron box formed after the initial stamping can be reduced by the re-stamping process.

Cut the iron sheet into rectangular iron sheets, roll the blank into a cylindrical shape, and weld the seams at both ends longitudinally to form a cylindrical shape. Use mechanical methods to seal the head of the cylinder with the circular end cap, and install the finished can lid at the other end to form a packaging iron can. The container consists of three parts: the can body, the can lid, and the can bottom, so it is called a three-piece can. Ordinary iron cans use three-piece cans, and aluminum cans use two-piece can technology. The patch uses offset printing technology. This type of three-piece can is not easy to hold candles and is easy to leak wax. If you must use it, it is recommended to use glue to prevent wax leakage. Usually, this type of three-piece can also needs to be treated with anti-rust treatment on the outer surface, and printing is still necessary. When making three-piece cans, pay attention to cutting corners and cutting before the folding process; in the welding process, wipe off the solder at the welding point, turn the edge after cooling, and the can body is completed.

Packaging tin cans are widely used in all walks of life because of their good printing performance and beautiful metallic luster texture retention performance. This is because the tin can production process is unique, coupled with colorful graphic printing and advanced metal processing technology, it is deeply loved by consumers!
