Analysis of the manufacturing process of tinplate box

We can see in many forums that many people searched for tin box manufacturing process, presumably everyone is ready to order a batch of tin box containers. In fact, the manufacturing process of tin box is not so simple. The following editors will introduce the production process of tin box for everyone, so that you can have a comprehensive understanding of the tin box process.

Tin box production, stamping and forming

Tin box forming is to use the punch part of the punching equipment to punch the iron material into the pre-made shape mold, and use the pressure of the pressure to deform the tinplate material. The tin can formed by initial stamping has a larger diameter and can be reduced by the re-stamping process.

Cut the flat sheet metal into a rectangular iron sheet, roll the blank into a cylindrical shape, and weld the joints at both ends to form a cylindrical shape. The end of the cylinder and the round end cap are mechanically rolled and sealed, and the other end is loaded with the can lid that was just made to form the original packaging tin box. The container is divided into can body, can lid, can The bottom consists of three parts, so it is called a three-piece can. Generally, tin cans use three-piece cans, and aluminum cans use two-piece cans. The technique used on the patch is offset printing. This type of three-piece cans is not recommended for candles. Must be used, it is recommended to use glue coating (excluding tax) at the bone joint to prevent wax leakage. Usually this three-piece can also pay attention to prevent rust on the outer surface, it still needs to be printed. Pay attention to the production of three-piece cans: before the end folding process, the corners and cuts must be cut first; in the soldering process, the solder scraps must be wiped off after soldering, and then turned over after completely cooled. At the edge, the can body is completed.

In addition, it is necessary to pay attention to the requirements of the drawing tin box manufacturing process: the outer surface of the beverage can must also be coated, printed and decorated, the inner surface coating, the open end must be flanged and closed. For the food tin box, the outer surface coating, the final flange forming at the open end, the barrel pressure ripple and the inner surface coating treatment should be performed during the cleaning process. If the bottom end of the tin box is used on a multi-die press The coated plate is made of corrugated lid to strengthen the iron box to bear the internal and external pressure. Tin box packaging is widely used in various industries and fields because of its excellent printing performance, beautiful metallic luster texture, long-lasting performance, etc., because the tin box production process has its own uniqueness, and then it is equipped with bright colors on the outer surface The graphic printing and advanced metal processing technology are widely loved by consumers in the market!

The environmental protection of tin box packaging requires that the tin can be well stored in the environment, can naturally oxidize and automatically return to the original iron oxide state, and return to nature. Naturally decomposed, it will not remain as a plastic product causing environmental pollution. At the same time, the production of the tin box does not require the felling of trees, will 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 more hygienic, and can more effectively reduce the output of garbage. It has direct and obvious economic benefits for recycling operations, and has become a trend in the use of various industries.
