How aluminum cans are produced？
How cans are produced1) Round cup punch
The thin aluminum strip is punched into a round cup by a cup punching machine. The cup punching machine is similar to a punching machine. The upper die and the lower die work together under the pressure of the machine to press the aluminum sheet through the die at the same time.
2) Deep drawing
The punched round cup is drawn into the shape of a high aluminum can usually seen by a deep drawing machine.
3) Bottom recess punching and upper edge trimming
The bottom of the cans that are usually bought generally have a concave design, mainly to hold carbonated beverages so that the can body does not expand.
4) Can body cleaning and printing
Can body forming generally requires a lot of lubricating oil to complete the die, so the finished aluminum can will be very greasy, and it needs to be rinsed and dried 6 times to meet the industry standard.
