Question: How to make can?

How is a can of Coke made?

Soda cans are made from aluminum — and trace amounts of other metals, including magnesium, iron, and manganese. Before the cans are created, the metals need to be extracted. Aluminum is made from Bauxite, an ore found mostly in Jamaica and Guinea. These are materials are refined into an aluminum oxide called Alumina.

What materials are used to make cans?

Cans are made of three different materials: aluminum, tin-coated steel ( tinplate ) and electrolytic chromium coated steel (ECCS).

How are cans printed?

Clean cans are fed into the printer and are placed on a steel mandrel. The spinning mandrel then rotates the can body against the rotating blanket, resulting in the transfer of the final graphic image onto the can body. Other coatings are applied after the ink, and then are sent to the UV ovens.

Will Coke eat through the can?

Soda is made up of carbonated water, sugar, and acid. Coke in particular has 0.06% acid and has a pH between 2.4 and 2.8. Coke is very acidic and, having at least two types of acids, it needs the polymeric coating that it has or the acids would eat through the can and the results of that would be disastrous.

Why do coke cans leak?

Cans are stored under pressure. Over time the acids under pressure (citric acid, carbonic acid and phosphoric acid) eat away at the inner can faster than they would under normal atmospheric conditions. This creates “holes” in the can or makes the aluminum more porous such that water molecules can escape.
