tinplate box,tinplate can The production process is not difficult to say, but not as simple as it should be. The price of tinplate boxes is also composed of several key points.

<1, tin cans are all produced using internally painted empty cans, the purpose is to better improve the corrosion resistance of metal packaging tin can containers; at the same time, the electrochemical interaction between metals can also be a small amount of iron dissolved in the metal tin cans, in the form of divalent iron in sealed tin cans of food, easy to be absorbed quickly by the human body The cans can be easily absorbed by the human body, which is beneficial to the needs of human health.

2、Making of tinplate boxes, stamping and forming. That is, the use of a punch in the stamping machine, a small amount of iron in a piece of dissolved, in the form of divalent iron in sealed tin can food, easy to be absorbed quickly by the human body, which is conducive to human health needs.

2、Making of tinplate boxes, stamping and forming. That is, using a punch of the stamping machine, a flat tin plate is punched into a cylindrical punching die, thus deforming the metal plate under pressure to make a round iron box. The diameter of the iron box formed by the initial stamping is larger and can be reduced by a re-stamping process.

3. Cut the flat iron into rectangular pieces, roll the blanks into a cylindrical shape, and weld the two ends of the joint lengthwise to form a garden cylinder. One end of the cylinder and the round end caps are mechanically rolled and sealed, and the other end is filled with the lid of the can just made to form the original packaging iron box, the container is divided into three parts: the can body, lid, and bottom, so called the three-piece can. General tinplate boxes are used three-piece cans, aluminum cans are used more two-piece can technology, the patch is used on the offset printing technology, this type of three-piece tin box is not recommended to bear candles, prone to leakage, if you must use, it is recommended to use glue coating at the joint (excluding tax) to prevent leakage of wax. Usually this three-piece tin should also pay attention to prevent rusting on the outer surface, or the need to use printing. In the production of the production of three-piece cans need to pay attention to: before the process of end-folding must first cut the corner and cut the lack; in the tin welding process, tin welding after welding to wipe off the tin scraps, to be completely cooled before the flap, the can body production is complete.

For beverage cans, the outer surface must also be coated, printed and mounted, the inner surface coated, and the open end must be flanged to form and close the mouth. For food tin boxes, the outer surface should be coated during the cleaning process, the open end should have the final flange molding, the barrel pressure corrugation and the inner surface coating treatment. If the bottom end of the tin box is made on a multi-mold press with pre-coated plates, the can lid should be pressed with corrugation as a way to strengthen the tin box to bear the internal and external pressure. Iron box packaging is widely used in various industries and fields because of its excellent printing performance, beautiful metallic luster texture, long-lasting performance and other characteristics, because the production process of iron boxes have their own special characteristics, and then on the outer surface with bright colorful graphics printing and advanced metal processing technology, widely loved by consumers in the market!

Tinplate box packaging environmental protection, requires tin cans can be well stored in the environment, can be naturally oxidized and automatically return to the original iron oxide state, back in nature, so the discarded iron box pile is available to use time for natural decomposition, and will not be like plastic products left to cause environmental pollution. At the same time, the production of iron boxes does not need to cut down trees, which will not destroy the balance of the marketing ecosystem and meet the overall requirements of international environmental protection products. The use of iron box packaging is safer, more hygienic, and more effective in reducing the production of waste, has direct and obvious economic benefits for recycling operations, and has become a trend in the use of various industries.

Iron box price cost composition

To purchase inexpensive and high quality iron boxes, you must know the important factors that make up the price cost of iron box production, of which the complexity of the process of making iron boxes is a key to the cost composition: the production process is simple and requires no complexity, the price of iron boxes will be cheaper, such as round For example, round iron boxes are generally simpler than square iron boxes, so the price of the same material tin box will be cheaper than the price of a square iron box. Secondly, transportation cost and demand is another key that affects the cost of iron boxes, which need to be transported to customers through logistics. The transportation cost is also a factor that affects the price of iron box. The transportation cost for long distance is relatively expensive, in addition, the breakage in transit will also cause the cost of iron box to rise.
