The food-grade metal storage box is a storage box made of tin-plated thin steel plate through different processes such as welding, stamping or buckle bone, which can be used to package and protect items. When the finished production of the food-grade metal storage box is completed, the finished iron box needs to be inspected to see if its quality meets the relevant standards.

Tin cans are made of tin-plated iron after printing, and can be classified according to different standards: According to shape: can be divided into round cans, rectangular cans, square cans, oval cans, heart-shaped cans, special-shaped iron tank. According to structure: can be divided into two-piece cans and three-piece cans...

Tin can color printing surface inspection requirements: A. The color registration is accurate, the pattern is beautiful, the text is clear, complete, not deformed, there is no obvious blur, the font has no double shadows, missing pens, broken lines, etc.; there should be no obvious color difference between the sheets and the bar code is clear.

This article introduces the performance, characteristics and classification of metal packaging materials, including steel packaging materials, tin-plated iron packaging materials, metal packaging containers, etc., and introduces the production process of metal packaging products, the basic principles of packaging cans and the differences Different application areas of metal products.

The anti-corrosion system of tin cans is based on steel materials, and a layer of anti-corrosion coating is applied on it, which is further improved through canning or spraying process. Therefore, the corrosion resistance of tin cans is mainly affected by the following factors.

The price of tin box packaging customization is mainly composed of the following parts: design fee, proofing fee, plate making fee, printing fee, printing fee, material cost, and the cost of manual production of tin box packaging in the later period. The reason why the price of the same tin box packaging is different lies in the difference in materials and craftsmanship used.

In the metal box packaging production project, the metal packaging box industrial technology is relatively cumbersome and demanding. This article introduces what industrial technology is needed in the production of metal packaging.

Summary: First cut the tin-plated iron sheet material into squares, then roll the material into a cylindrical shape and then solder the formed longitudinal bonding wires to form a side seal, one end of the cylinder (iron tank bottom) and a circle The shaped end cap is mechanically formed with a flange and rolled and sealed (this is a double crimping seam) to form the can body; the other end is filled with the product and then the can cover is sealed. This is the basic step of making a metal...

  In the production of metal cans, if each surface has a flat screen background color, then the production quality needs to check whether the background color is consistent. Some customers have designs in the product that look the same, but in fact The ingredients inside are not the same, which requires caution in each printing workshop.

The tin box company's order quantity is largely determined by the quality of the tin box, and the tin box mold determines the quality of the tin box. This article sorts out the tin box mold grinding and polishing process operating guidelines for everyone. As long as these guidelines are followed, high-quality tin boxes will be produced, and the order volume will definitely increase year by year.

Tin boxes and metal boxes are durable goods, with higher surface decoration requirements and more durability. Therefore, a number of surface treatments are required before printing, such as surface coating, electroplating, anodizing or mechanical finishing (spinning, drawing), etc. Printing When working, ensure that the surface is clean and wear gloves when working. If there are stains such as grease, fingerprints or dust on the treated surface, it must be washed away with solvents such as...
