1. The forming of the tinplate box is to use the stamping part of the stamping equipment to stamp the iron material into the prefabricated forming mold, and use pressure to deform the tinplate material. The diameter of the iron box formed by the initial stamping is large and can be reduced by the re-stamping process.
The flat iron sheet is cut into rectangular iron sheets, the blank is rolled into a cylindrical shape, and the joints at both ends are longitudinally welded into a cylindrical shape. One end of the cylinder and the round end cover are mechanically rolled and sealed, and the other end is equipped with a freshly made cover to form the original packaging iron box. The container is divided into three parts: the body, the lid and the bottom, and it is called a three-piece can.
Tinplate boxes are mostly made of three-piece cans, while aluminum cans are made of two-piece cans. The patch adopts offset printing technology. This type of three-piece iron box is not recommended for candles, which are easy to leak. If you must use it, it is recommended that the joints be coated with glue (excluding tax) to prevent wax leakage. Usually this three-piece can also pay attention to prevent the outer surface from rusting, or to print. Attention should be paid when making three-piece cans: the corners and notches must be cut off before the end folding process; In the welding process, the solder chips should be wiped off after welding, and the can body should be turned over after it is completely cooled.
2. What we need to pay attention to is the requirements of the development process of punching iron boxes: the outer surface of Chinese beverage cans must be continuously analyzed and coated, printed and assembled, coated on the inner surface, and flange forming and closing must be performed on the open end. For food iron boxes in our country, an influence coating on the outer surface should be carried out during the cleaning process, and the open end can be studied for the final flange forming, cylinder pressure corrugation and inner surface coating technology. If the bottom end of the iron box is made of pre-coated plates on the multi-mold design pressure computer, the tank cover should be pressed with corrugation to further strengthen the inner and outer pressure of the iron box.
Iron box packaging is widely used in various industries and fields because of its excellent printing performance, beautiful metallic luster texture, and long-term performance. Because the iron box production process has its characteristics, it uses color graphic printing and advanced on the outer surface. Metal processing technology is well received by consumers in the market!
Tinplate is an environmentally friendly material that can be oxidized and decomposed in the natural environment, and can return to nature without causing environmental pollution. Meet 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. Recycling operations have direct and obvious economic benefits. The use of iron box packaging in various industries has become a trend.
