The main process flow includes cutting boards, rolling iron into circles, positioning welding, internal and external coating of welds, drying, flanging, sealing, leak detection, etc. Some processes can be selected and configured according to the needs of the tank type.

It is widely used in the food and beverage industry, such as the packaging of tea drinks, protein drinks, Babao Congee and other products, as well as in the chemical industry, daily necessities and other fields.

The three piece can is assembled from the body, bottom and cover. The body can flexibly change the height by adjusting the plate size (such as 100ml small can to 5L large can), and can also be made into round, square, shaped and other types of cans, especially suitable for products with non-standard capacity or special shape requirements (such as Babao Congee cans, protein powder cans, chemical reagent cans).

The three piece can made of tinplate/chrome plated steel plate has a compressive strength of 200-300kPa and can withstand high temperature sterilization at 121 °C (such as canned meat and high-temperature sterilized beverages). The sealing structure is stable under high temperature and will not leak due to deformation. Compared to plastic and glass bottles, it is more suitable for food/beverages that require high-temperature sterilization and long-term storage at room temperature (such as luncheon meat and herbal tea).
