Tin cans are made from different varieties of metal

Tin cans are made from different varieties of metal. Steel, aluminum, tin, steel plate and other metals are used for manufacturing tin cans. The manufacturing of tin cans is very simple as compared to the production of steel or aluminium cans. All that needs to be done is to heat the metal, pour the melted metal into a mould and then the lid is fitted on the can.

Tin can manufacturing is generally used for the manufacturing of tinned products like tinned meat, fish and vegetables. Steel and aluminium cans are not suitable for manufacturing of tinned products. The tin can has been in existence since quite a few years and it is gaining momentum and is expected to gain even more popularity in the coming years. Food can manufacturing is a profitable business today and there is no shortage of raw materials. Right from ore to finished product, everything in this world can be manufactured from two-part metal tins.

Two-piece metal cans are generally manufactured by taking the first can and bending it into the shape of the desired object. The bending can either be horizontal or vertical. In case of a horizontal bend, the bottom edge of the can will be slightly above the rim of the tin can and the top edge will be exactly on the same level as well. In case of a vertical bend, the bottom edge of the can will be slightly below the rim of the tin can and the top edge will be above the rim. These can shapes can also be made into other shapes like rounds, cylindrical, flat and so on.

The most popular type of tin can is the flat surface can. This is created by forcing the hot air into a tube which is then shaped into the desired form. Forcing of the hot air into the can may take a couple of hours. Once the metal has been forced flat, the sheet metal is bent at right angles to create the flat surface. The bending is aided by welding or bolting and the entire procedure is done under high temperature.

The other most common type of tin can is the one with a bpa content. The content of the tin in these cans is actually the product of the recycled plastics. The materials which are recycled for manufacturing of the tin cans include paper, metal and glass. When these materials are used, they produce a waste that is no good for the environment. Hence, these can be sold by the beverage industry for recouping the cost involved in making the cans.
