Each can is made of iron - printing - cutting - stamping - assembly - packaging, step by step.

1. Iron materials: generally after confirming the order, we will order the most suitable iron materials according to the typesetting drawing. We can choose the iron materials: frosted iron, frosted iron, base plate iron; The thickness of iron in 0.23-0.35mm, about the iron quality identification, can usually visual inspection method, to see whether there are scratches on the surface, whether the lines are uniform, whether there are rust spots, etc., with the same micrometer can measure the thickness of the printed coating, with the hand can feel its hardness.

2. Printing: The printing team makes typesetting drawing according to the design drawing of the tin box and prints according to the typesetting. Usually, the template is provided to the printing department to follow the color. These problems are professionally controlled. Printing process: white magnetic ink printing, is a special ink anti-counterfeit printing technology, ink filled with magnetic materials for printing. White ink factor: white ink can only be printed, not coated, because some of the process requires partial iron penetration, the use of white ink process. Through iron printing: without white magnetic, directly print the pattern on the base of oil, so as to show the effect of iron grain.

3 cutting: printed tinplate material can be cut according to the row cutting bed, in the cutting mattress must pay attention to is to cut according to the knife edge line, length is closed, even. Operators should be prevented from scratching each other during feeding and should strictly follow the working procedure.

4 stamping: in the stamping machine for the iron box die installation, and then the iron sheet stamping forming, usually a can to be divided into three procedures to complete. The general procedure of the two cans of the heaven and Earth cover is: cover: opening material - flying edge - winding line.

Bottom cover: opening - flash - prewinding - winding. The bottom process of the lid of the world (the bottom) can, the lid: opening - flying edge - winding line; Tank body: opening material - pre-bending - shearing Angle - shaping - buckle bone - punching body (buckle bottom)- sealing bottom. The bottom process is: open material. If the tin can is hinged, then the lid and the body have an additional procedure: hinge.

In the process of stamping, product loss is usually the largest. It is necessary to pay attention to whether the work operation is standardized, whether there is scratch on the surface of the product, whether there is batch seam on the winding line, and whether the buckle position is fastened. The usual practice is to arrange the production of large sample before the production of large goods, and carry out the production according to the confirmed large sample, so as to reduce errors.

5. Quality inspection: accept products to be inspected; According to the sampling standards to be performed; Inspect products according to inspection standards (or inspection manuals, or ZHI's drawings, or specifications); Issue inspection qualification report.

6. Packaging: After the products pass the test, the packaging department shall be responsible for cleaning and assembling, putting the products into plastic bags and packing. This part is the finishing work of the product. Cleaning of the product is very important, so the cleaning work should be done before packaging, and then packaging should be carried out according to the packaging method. For products with many styles, the model number and the box mark should be properly arranged, and the packing quantity must be accurate.
