What Are The Customized Processes For Iron Box Packaging?

The forming of a tin box is achieved by using the punch part of a stamping equipment to punch the iron material into a pre made shape mold, and using the applied pressure to deform the tin material into shape.
The diameter of the iron box formed by initial stamping is relatively large and can be reduced through re stamping technology.
Iron box packaging customization involves cutting flat iron sheets into rectangular iron sheets, rolling blanks into cylindrical shapes, and longitudinally welding the joints at both ends to form a cylindrical shape. One end of the cylinder and the circular end cap are mechanically rolled and sealed, while the other end is loaded into the newly made can cap to form the original packaging iron box. The container is divided into three parts: the can body, the can cap, and the can bottom, hence it is called a three piece can.
A typical tin box uses a three piece can, while an aluminum can uses a two piece can technology. The patch is made using offset printing technology. It is not recommended to hold candles for this type of three piece iron box, as it is prone to leakage. If it is necessary to use it, it is recommended to use glue coating (excluding tax) at the joint to prevent wax leakage.
Usually, attention should also be paid to preventing rust on the outer surface of this type of three piece can, and printing is still necessary. When producing three piece cans, it is necessary to pay attention to cutting corners and gaps before the end folding process; During the soldering process, the tin shavings should be wiped off at the solder joint after soldering, and the can body should be completed by flipping after it has completely cooled down.
In addition, it should be noted that the requirements for the manufacturing process of stamping and drawing iron boxes include coating, printing and installation of the outer surface of the beverage can, coating of the inner surface, and flange forming and closing of the open end.
For food iron boxes, during the cleaning process, the outer surface should be coated, the open end should undergo final flange forming, the cylinder should be corrugated, and the inner surface should be coated. If the bottom end of the iron box is made of pre coated sheet metal on a multi mold press, the can cover should be corrugated to strengthen the iron box's ability to bear internal and external pressure.
Iron box packaging is widely used in various industries and fields due to its excellent printing performance, beautiful metal luster texture, and long-lasting retention performance. Due to the unique production process of iron boxes, they are paired with brightly colored graphic printing and advanced metal processing technology on the outer surface, which is widely loved by market consumers!
The environmental protection of tin box packaging requires that iron cans can be stored well in the environment, and can naturally oxidize and automatically return to the original iron oxide state, returning to nature. Therefore, the stacking of discarded iron boxes can be naturally decomposed over time, and will not cause environmental pollution like plastic products.
At the same time, the production of iron boxes does not require the cutting of trees, does not disrupt the balance of the marketing ecosystem, and meets the overall requirements of international environmental protection products. The use of iron box packaging is safer and healthier, and can effectively reduce waste production. It has direct and obvious economic benefits for recycling operations, and has become a trend in various industries.
