Tin boxes are made from tin sheets or rectangular pieces of metal that can be easily folded into a box and sealed with tape. The process of making tin boxes is relatively simple, but it requires some specialized tools.
Typically, factories make tin cans by printing,cutting,and stamping .
Let’s take a closer look at how these practical and durable canisters are made.
Usually Tin manufacturing plants need to purchase tinplate , the tin plates in coils or big rolls .Before printing, the tin roll is unrolled and passed through a pressing machine to make it flat. Then it will be cut into the desired size sheets,the tin plates sheets will be sent to printing house .
Step 1 .Printing
First, Machines paint the tin plates with a white coating to prepare them for the designs. This coating will also protect the tin boxes from rust.
After that printing machines will print designs on white-coated tin plates. The plates are passed through the printing machines and come out with the printed-design. After going through the printing machines, the sheets are fed into an oven for drying.
Finally, a layer of glossy /matte varnish is done on the tinplate .
The varnish layer helps protecting the tinplate during the cutting & forming process as well as making the colour long-lasting on shelves & during usage by consumers. Of course, after varnishing, the whole sheet will be sent through oven for drying one more time .
Step 2 : Cutting
The Whole Sheet, which is on the conveyor belt, will pass through an industrial-grade Slitting machine,which tinplate sheet will be cut into smaller pieces tinplate sheet of required size of one tin box accordingly.
Step 3: Stamping
The factory forms tin boxes through machines that mold their shape. After molding, another machine compresses the edges of the box before the boxes are sealed with a sealing machine.
Tin can Cover Making
The cover-making process begins by cutting and stamping . Once the cover is cut and it will pass through a machine that stamps the body and lid accordingly.
They will then pass the cover through a machine that turns it into its final shape. Excess parts are then cut off and the cover is crimped or compressed.

A two-piece tin can
A two-piece tin is made by using a stamping method to form the body and bottom parts, then adding a separate lid.
