For the production of tin box, the round tin box is a very good stamping shape, because it only needs to bend the iron sheet to form, while the square tin box,if the stamping is not done well at the beginning, it will crack, and the product will not form. So every step should be careful.

It seems that the simple square tin box also has this risk, not to mention the irregular shaped tin box. In the process of stamping, the deformation of irregular shaped tin box is very large, and it is very easy to exceed the limit, so the risk of scrap will be relatively large, and the loss will also increase. Tinplate tin box packaging is widely used in our life, various kinds of packaging are square, round, irregular and so on.

Tin box as a popular consumer packaging. Due to the tin box material and processing technology, there are more novel types of irregular shaped tin box popular by consumers. However, the irregular shaped tin box is more exquisite and harder to press than the ordinary tin box, so the cost will be higher.
