What parts does the structure of a tin can consist of?

As a common metal packaging product, iron cans have various structures and processing categories, which leads to many people not knowing enough about their structure. According to the structure and processing method of iron cans, iron cans are generally divided into two-piece iron cans, three-piece iron cans and aerosol iron cans. These different types of iron cans can be stamped into various shapes, such as round iron cans, square iron cans, and other special-shaped iron cans.

Two-piece iron cans consist of two parts: a can lid and a can body with a bottom. The can body and the can bottom are hollow wholes processed by the stretching forming process. This forming method belongs to the stamping and stretching process, so the two-piece iron can is also called a stretching can. There are many types of can bodies for two-piece cans. According to the height of the can body, they are divided into shallow punching cans and deep punching cans; according to the can-making materials, they are divided into aluminum cans and iron cans; according to the manufacturing technology, they are divided into thinning stretching cans and deep drawing cans, etc.

Three-piece iron cans consist of three parts: can body, lid and bottom. The can body and bottom of the three-piece can are made by combining two pieces of iron sheets, and there are relatively more processes. The process of three-piece cans can be divided into many different forms, including sealed bottom, buckled bottom, and hinged bottom. Three-piece cans are very common in the market, such as beverage cans Wanglaoji, mooncake tin boxes, etc., all of which are three-piece tin can structures.

Aerosol tin cans are mainly used to package spray products, such as hairspray, insecticides, etc. The design of aerosol cans needs to consider pressure-bearing capacity and safety, so their structure and material selection are different from ordinary canned products.

The diversity of the structural design and production process of tin cans enables them to meet a wide range of market needs. Understanding the structural characteristics of different types of tin cans will help us better select and use these products. The classification and characteristics of tin cans are not only reflected in their structure, but also involve their use and production process. These factors jointly determine the final application effect of the tin can.
