The two-piece metal tin can was introduced in the middle of the 20th century. All the metal packaging cans are composed of two pieces, namely the body and the lid, so it is called two-piece metal tin can. The metal tin can bodies of the two pieces of cans are made of sheet metal, which are stretched and deformed by a punch through a drawing forming die, so that the can bodies at the bottom of the cans are integrated.

There are many kinds of tins for two pieces of tins: according to the height of the metal tin can body, they are divided into shallow cupping and deep cupping; according to the metal tin can making data, they are divided into aluminum cupping and tin cupping; according to the manufacturing skills, they are divided into thin drawing cupping and deep drawing cupping cupping. Two-piece cans are related to three piece cans. The classification and characteristics of two piece metal tin cans are introduced​.

1.Good sealing performance. The metal tin can body is directly formed by punching and drawing technology, without leakage, and the leakage detection process can be avoided.

2.Ensure the quality of goods. The two pieces of metal tin can do not need to be welded and sealed to prevent the lead pollution of the metal tin can, and it is resistant to high temperature sterilization, which can ensure the cleanness of the goods.

3.Beautiful and generous. The tin can body has no seams, beautiful appearance, and the tin box can be decorated and printed one after another with good effect.

4.High production efficiency. There are only two parts for two-piece can, and the tin box manufacturing technology of the can body is simple, which has great advantages in simplifying the technical process and improving the production capacity.

5.Save the original data. The tin can body of two-piece can is stretched and deformed during forming, and the wall thickness is thinner than that of three-piece can; In addition, the metal tin can body of two-piece can is fully formed, and there is no longitudinal seam of the metal tin can body and seam with the bottom of the metal tin can for the tinplate box, which also saves materials.
