Aluminum alloy has low density, high specific strength, good electrical and thermal conductivity, and good corrosion resistance. It is widely used in fields such as food packaging, navigation, aviation, automobiles, petrochemicals, telecommunications, atomic energy, and space technology. Aluminum alloy sheet cans made of aluminum alloy have a dense structure and no defects such as shrinkage cavities, shrinkage porosity, and cracks. During production, the casting process can be optimized and casting defects reduced by numerically simulating the filling and solidification processes of the tank.

The requirements of modern society for beer cans, beverage cans and food cans are: (1) The can can prevent the external environment (light, gas and mechanical action) from damaging the packaging; (2) The can itself does not damage the packaging and will not be packaged (3) Cans can be supplied in various applicable specifications; (4) Cans can help people identify packaging and easily achieve the purpose of attracting customers; (5) It is convenient for customers to use food; (6) Cans can be used in general Filling and loading and unloading on filling machines and loading and unloading machines; (7) Tanks should be as economical as possible.

Aluminum alloy sheet cans can meet the above requirements. It is opaque to light and impermeable to air, water vapor or other gases. Any current processing methods for preserving food (freezing, dehydration or sterilization heat treatment) have no effect on it. Aluminum alloy sheet cans are odorless and do not contribute to bacterial growth. Choosing a suitable aluminum alloy can can resist the chemical attack of dry packaging and wet packaging with a pH value close to neutral, and the resistance will be stronger after painting. The thin plate has good formability and can be made into containers of various specifications and shapes. It can be made into a whole tank with no seams on the sides and bottom, avoiding the potential weaknesses of ordinary containers in these parts. When used to package pressurized beverages, creep damage at the side joints is also avoided. The natural surface of aluminum alloy is glossy silver-white, and it is easy to accept surface treatments such as spray painting and coloring.

Aluminum alloy can be used to make can lids that are easy to open, making it easy for customers to open the lid and eat the food quickly. For jars containing solid food, the lid can be torn off and the food can be poured out easily. Cans for liquids such as beer and beverages also come with an easily removable lid. Aluminum alloy food cans can be made as hard as tin food cans and can be filled with food at high speeds on conventional standard filling lines. However, due to economic reasons, the advantages of aluminum alloy performance are often used to make certain modifications to the filling equipment, especially the dependence of conventional equipment on magnetism. Secondly, considering the light weight of aluminum alloy sheet tanks and the lack of joints at the bottom of the tank, Make some modifications such as sewing etc. At present, the side wall thickness of beverage cans has been reduced to 0.114--0.152 mm. When packaging beer and soft drinks containing carbonated gas, the gas contained in the beverage can enhance the resistance of the side wall of the can to external mechanical effects. (orange juice, grape juice, strawberry juice, etc.), add a drop of liquid nitrogen to the tank, and then cover it. After the liquid nitrogen turns into gas, the volume increases 700 times, which enhances the resistance of the tank side wall to external mechanical effects.

Food-grade aluminum is 3004 aluminum alloy, which is mainly used as metal packaging materials in the form of sheets and foils, and is made into cans, lids, bottles, barrels, and packaging foils. Widely used in packaging of beverages, food, cosmetics, medicines, cigarettes, industrial products, etc.
