Background
Two-piece cans were made in the middle of the 20 th century. The whole packaging can consists of two parts, namely a can body and a can cover, so the packaging can is called a two-piece can. The two can bodies are made of thin metal plates by drawing and shaping with a punch press to make them deform and become a whole.
The body classification of two jars has the multiple: according to the height of the can body, dividing a shallow-punching can and a deep-punching can; dividing an aluminum can and an iron can according to the can making materials; according to the manufacturing technology, the thin drawing cup and the deep drawing cup are divided. Two-piece cans have the following advantages over three-piece cans: the can body is directly formed by punching and drawing process without leakage, and the leakage detection process can be omitted. The can body has no seam, and is beautiful in appearance, and the can body can be continuously decorated and printed, and the effect is good. The two-piece tank has only two parts, and the tank body has simple manufacturing process, thereby being beneficial to simplifying the process and improving the production capacity.
