Manufacturing Process Of Tin Box

What is a tin box for? Literally, it should be a storage iron box. Tinplate boxes are mainly used for the production of food packaging iron boxes and cans, because tinplate combines the strength and formability of steel with the corrosion resistance, solderability, and aesthetic appearance of tin in one material, with the characteristics of corrosion resistance, non-toxic, high strength, and good ductility.
Each iron can is completed step by step through the process of iron material printing cutting stamping assembly packaging.
1. Iron material: Generally, after confirming the order, the most suitable iron material, type, size, etc., will be ordered according to the near layout diagram. Iron material is usually stored directly in the printing factory. Regarding the quality evaluation of iron material, it can be visually inspected to see whether there are scratches on the surface, whether the patterns are uniform, whether there are rust spots, etc. The thickness can be measured using an equal micrometer, and its hardness can be felt by pressing it with your hand.
2. Printing: After both the film and layout are provided to the printing factory, the printing factory arranges and assembles them for printing. Usually, templates are provided to the printing factory for color matching. During the printing process, it is important to pay attention to whether the printing color matching matches the template, whether the positioning is accurate, whether there are stains, scars, and so on. These issues are generally under the control of the responsible printing factory.
3. Cutting: After the printed iron material is returned to the factory, it can be cut and cut according to the cutting bed. When using the cutting pad, pay attention to whether the operator cuts according to the cutting edge line, and whether the length is consistent and even. Whether workers scratch each other during material placement should be checked for quality at the initial operating position.
4. Stamping: It is not only the pressing and forming of iron sheets on a punching machine, but also the main task of making cans. Usually, a can can can be completed through multiple processes. The general process of the two piece jar of Tiandi Lid is as follows: Lid: opening - trimming - winding. Bottom cover: cutting - trimming - pre winding line - winding line.
The bottom sealing process of the Heaven and Earth cover is the process of the can. The cover includes cutting, trimming, winding, and the can body includes cutting, pre bending, corner cutting, forming, bone clamping, punching (bottom sealing), and bottom sealing. The bottom process is: cutting. If the iron can is hinged, then the lid and body each have an additional process: hinge.
During the stamping process, the product is usually the most worn out. It is important to pay attention to whether the work operation is standardized, whether there are scratches on the surface of the product, whether there are batch seams on the winding line, and whether the buckle position is tightened. The usual practice is to arrange for confirmation of the production sample before producing the bulk product, and produce according to the confirmed sample, which can reduce a lot of trouble.
5. Packaging: After production is completed and stamped, the packaging department is responsible for cleaning and assembling, placing in plastic bags, and packing. This stage is the final work of the product, and the cleanliness of the product is very important. Therefore, before packaging, it is necessary to do a good job of cleaning, and then package according to the packaging method. For products with multiple styles, it is necessary to align the model number and box label and place them together. During the packaging process, it is important to minimize the flow of defective products into the finished product and ensure accurate packing quantity.
