Can anyone tell us about the process of making cans?

In fact, the process of making cans is quite simple.

As someone who works in a can factory, I know a lot about the production of cans, which is mainly divided into the following steps.

The first step is stretching. Draw a piece of coil very thinly.

Second, trimming.

Third, spray paint drying.

Fourth, packaging.

First of all, let's illustrate a concept: metal cans are divided according to structureTwo-piece canswithThree-piece cans。As the name suggests, the three-piece can is composed of three parts: the can body, the bottom of the can and the lid of the can, the body of the can has seams, the body of the can and the lid of the can, and the bottom of the can; The two-piece can is composed of two parts: the can lid and the overall seamless can body with a bottom, and the can body and the can lid are sealed.

When using aluminum as the material, it is mainly made into two cans, and when tinplate is used as the material, it is mainly made into three cans, and the difference between the two is mainly the manufacturing process of the can body. <>

Cans are all machine-made. Basically, aluminum coils of similar thickness of construction paper are used to punch out discs with stamping machine tools to process them into cups and cans, and the remaining parts are processed into cans and cooled during processing. After processing, through pruning, cleaning, drying, painting, printing and other processes, the basic navigation is formed.

In fact, it is very simple, the cans are first used with an aluminum skin, and then folded together, at this time they are welded with some particularly advanced welding technology, and finally the corners are rolled up and buckled, and then some things are added to make the can.

In fact, the process of making cans does not smell bad, and if you make cans in an ordinary factory, it mainly does these steps.

The first step is stretching. Draw a piece of coil very thinly.

Second, trimming.

Third, spray paint drying.

Fourth, packaging.

In fact, we can see that his production steps are quite simple, and then the production cost may be a little larger.

The production process of cans is actually quite simple, mainly after melting some molten aluminum, and then pouring it into the mold to cool quickly, after cooling, these cans are marked with fonts, or packed with wrapping paper, which forms the cans we see.

In fact, making cans is very simple, first of all, the aluminum is melted, and then put into a mold The mold is the shape of the can, and when it is solidified, add the lid we see on the upper part of the can, and then seal it, and finally add packaging and paint, and it is completed.

This is very simple, the small handle on the top is punched out with a punch pet, but he is formed from the bottom up, where we see a bump, and then the small wrench can be plugged up. The marks on the edge are punched out by the punch in this place, and it is also an area where the force is concentrated, and when you pull, it will pull along the punch traces.
