Tinplate cans, as a common type of metal packaging container, are widely used in industries such as food, cosmetics, and daily necessities. Their exquisite printing and unique can shape not only enhance the appearance of the product but also serve as good protection. So, how are tinplate cans made? Today, let’s take a detailed look at the production process of tinplate cans.
I. Preparation of Tinplate
The production of tinplate cans begins with the preparation of tinplate. After confirming the order, the most suitable tinplate will be ordered according to the layout diagram, including the type and size of the tinplate. In terms of tinplate quality identification, visual inspection methods are usually used to check whether there are scratches on the surface, whether the lines are uniform, and whether there are rust spots, etc. In addition, a micrometer is used to measure the thickness, and the hardness is felt by hand to ensure the quality of the tinplate.
II. Printing Process
Printing is a key link in the production process of tinplate cans. After receiving the film and layout diagram, the printing department will carry out typesetting and printing according to the layout diagram. To ensure printing quality, customers usually provide sample plates for color matching. During the printing process, it is necessary to pay close attention to whether the printing color matches the sample plate, whether the registration is accurate, and whether there are stains and scratches.
III. Cutting Process
After printing the tinplate, it needs to be cut according to the layout bed. During the cutting process, the operator needs to cut along the knife edge line to ensure that the length is appropriate and uniform. At the same time, attention should also be paid to whether the workers scratch each other when placing the material to control the quality from the source.
IV. Stamping and Forming
Stamping and forming is the core process of making tinplate cans. On the punch press, the iron sheet is pressed into the required shape, and usually a can requires multiple processes to complete. For example, the two-piece tinplate can with a lid needs to go through multiple processes such as blanking, trimming, and coiling. During the stamping process, special attention should be paid to standardized operation to avoid scratches on the product surface and burrs on the coiling.
V. Assembly and Packaging
After stamping and forming, the next step is the assembly link. After assembling the formed can body and lid, they are tightly fixed through welding, flanging, and other processes. During the assembly process, the product also needs to undergo quality inspection to ensure that the product is intact. After assembly is completed, it enters the packaging link, cleans the product and assembles it, puts it into a plastic bag and packs it in a box. In the packaging process, attention should be paid to reducing the inflow of defective products into finished products and ensuring the accuracy of the number of boxes packed.
VI. Quality Inspection and Factory Shipment
The last step is quality inspection and factory shipment. The produced products are randomly inspected to ensure that the product quality meets national standards and customer requirements. After passing the inspection, packaging, warehousing, and other processes are carried out before leaving the factory for sale.
