Introduction to the production process of tinplate cans

As a representative of metal packaging products, tinplate cans have become an important factor in choosing packaging for many merchants with their exquisite printing layout and unique can shape. Don't underestimate this small iron can. The production of tinplate cans is a complex process. Today, the tin can manufacturer will introduce to you the production process of tin cans.

1. Materials

Common tinplate cans are divided into tinplate or frosted iron, with thicknesses of 0.21mm, 0.23mm, 0.25mm, 0.28mm, 0.30mm, etc., among which the commonly used thickness dimensions are 0.23mm, 0.25mm, and 0.28mm. The difference between tinplate and matte iron is that the texture of the material is not used. Ironplate has rougher stripes, while frosted iron has a strong metal sand effect. Therefore, the price of matte iron is several hundred more than that of tinplate.

2.Type printing

A piece of iron material usually has a size of 1100*960mm. The designer will type according to the cutting edge line of the production tank. After the layout is determined, plate making and printing are carried out. Usually this is handed over to the iron printing manufacturer to make the plate. The printing process is generally four-color + spot color printing. , The oil effect is printed according to the layout process determined by the customer in advance. For specific printing information, please refer to the tinplate printing process, which takes about 15 days.

3. Cut iron

The printed iron material is transported back to the factory for cutting. The operator cuts the iron material according to the edge line of the iron material, and divides the iron material into a can cover, inner cover, can body, can bottom and other parts. This process is a relatively fine canning process, requiring high cutting accuracy and years of cutting experience to operate.

IV. Stamping and forming

Cutting iron material stamping and forming. This is a mold that requires a complete set of iron cans to form. A simple tin can requires at least fifteen stamping processes. Including flashing, molding, winding, protrusion, etc. In the past, a stamping production line required more than a dozen operators, but with the popularity of automated production lines, stamping production lines have now been replaced by automated punches, and each line can only be operated by 2 people.

5. Packaging and transportation

Combining the stamping tank lid and the can body. During this process, check each can for defective products. This is the last step in the production of tinplate cans, and it is also a relatively important process. It is the key to the passing rate of a batch of tinplate cans.
