Introduce the production process of tinned iron metal box

The metal box is made of tin-plated iron. It is one of our common packaging boxes, such as tea boxes, gift boxes, coffee cans, biscuit boxes, perfume boxes, etc. Its anti-corrosion and anti-rust effect is very good, and it is easy to print and beautifully printed, so it is favored by more and more customers. So do you know the production process of tinplate boxes? Let me introduce it in detail below.

Each tinplate box is completed step by step by iron material-printing-cutting-stamping-assembly-packaging.

1) Iron material: Generally, after confirming the order, the most suitable iron material, iron material type, size, etc. will be ordered according to the nearest layout drawing. The iron material is usually stored directly in the printing plant. The quality of the iron material can be usually visually inspected. The method is to check whether there are scratch marks on the surface, whether the lines are uniform, whether there are rust spots, etc., the thickness can be measured with a micrometer, and the hardness can be felt by hand.

2) Printing: After the film and typesetting drawings are given to the printing plant, the printing plant arranges imposition printing. Usually, the printing plant will provide a template for the printing plant to follow the color. During the printing process, pay attention to whether the printing and color matching follow the model and set the position. Whether it is accurate, whether there are stains, whether there are scars, etc. The printing houses generally responsible for these problems can control themselves.

3) Cutting: After the printed iron material is returned to the factory, the material can be cut and cut according to the row of cutting beds. When cutting the mattress, pay attention to whether the operator cuts according to the knife edge line and whether the length is consistent and uniform. Whether workers scratch each other when unloading, etc., the quality must be checked at the initial operating station.

4) Stamping: It is to press the iron sheet into shape on the punching machine. This is the most important work of making cans. Usually, a can can be completed in many processes. The general process of the two-piece can of Tiandi Li is: Lid: opening-flashing-winding. Bottom cover: cutting-flashing-pre-coiled line-coiled line.

The process of lid and bottom closure (bottom closure) of the can, lid: opening-flashing-coiling can body: opening-pre-bending-angle cutting-forming-buckle-punching (bottom closure)-back cover. The bottom process is: cutting. If the can is hinged, then the lid and body will each have one more process: hinge.

In the stamping process, it is usually the largest loss of products. Pay attention to whether the work operation is standardized, whether the surface of the product is scratched, whether there are batch seams on the winding line, and whether the button is fastened. The usual practice is to arrange before the production of bulk goods. The production of large samples is confirmed, and production is carried out according to the confirmed large samples, which can reduce a lot of trouble.

5) Packaging: After the production is completed, the packaging department is responsible for cleaning and assembling, putting in plastic bags and packing. This link is the finishing touch of the product. The cleanliness of the product is very important. Therefore, it is necessary to do a good job of cleaning before packaging, and then package according to the packaging method. For products with many styles, the style number and box mark must be aligned and placed. put. In the packaging process, attention should be paid to minimize the influx of defective products into the finished product, and the packing quantity must be accurate.

The above is about the production process of tinplate boxes, interested friends come to pay attention to it. The characteristics of the tinplate box are corrosion resistance, high strength, very good ductility, and non-toxic, so people like to use it to make all kinds of packaging boxes. However, to ensure the quality of these packaging boxes, first of all, every step of the tinplate box production process must be paid attention to, because every step will affect the quality of the product. Everyone only needs to pay attention to this work and proceed in accordance with the rules and regulations, so as to ensure the production of qualified products.
