A kind of manufacturing technology of anti-counterfeit metal cover and anti-counterfeit metal cover

Abstract

The invention relates to a manufacturing process of an anti-counterfeit metal cover, in particular to a process of transferring information patterns to a metal surface by using a film as a carrier and stamping to form an anti-counterfeit metal cover, and the anti-counterfeit metal cover produced by the process. A manufacturing process of an anti-counterfeiting metal cover according to the present invention, the process is characterized in that it also includes the following steps: a composite process: further coating and curing an adhesive layer on the information protection layer, and compounding the film and the metal surface to position the film Adhere to the metal surface; peel off the film; stamping: In the stamping machine, the metal in the above steps is positioned and stamped to form an anti-counterfeiting metal cover. The invention uses the film as the carrier to transfer the information pattern, and the product effect is more superior; the precise positioning of the information pattern on the metal surface is realized; the film can be peeled off after compounding, so that the subsequent processing of the metal will not be affected, and it can be punched out according to the demand. A metal cover of a specific shape. And the stripped film is recycled, which greatly saves the cost.

Description

technical field [0001] The invention relates to a manufacturing process of an anti-counterfeit metal cover, in particular to a process of transferring information patterns to a metal surface by using a film as a carrier and stamping to form an anti-counterfeit metal cover, and the anti-counterfeit metal cover produced by the process. Background technique [0002] In addition to being used for the sealing of bottled or canned products, metal caps often need to be printed with color patterns on the metal cap to make it have the function of LOGO, or for anti-counterfeiting requirements, it is necessary to emboss a hologram on the surface of the metal cap pattern. [0003] In the prior art, in order to achieve the effect of having holographic patterns or color patterns on the surface of the metal cover, one is to print directly on the metal surface and then dry at high temperature; the other is to iron the film with the information pattern on the metal surface Printing, even if...

Problems solved by technology

Obviously, the first method is not only time-consuming and labor-intensive, but also the effect is not ideal. The printed pattern or pattern is rough, which cannot really meet the needs of decoration, anti-counterfeiting, etc.

Although the second method has improved the information pattern effect on the metal surface to a certain extent, its disadvantages are: 1. The temperature of the hot stamping process used is generally very high. The printing time must be very short, generally controlled within 0.2 seconds, and during this time, the melting of the adhesive layer is uneven, the adhesion effect is not ideal, and it is difficult to be firm, which often causes the information pattern on the metal to shift, resulting in anti-counterfeiting The metal cover is scrapped; 2. During the hot stamping process, the precise control of the film operation speed cannot be realized, so that the requirement for precise positioning of the information pattern cannot be realized; 3. After hot stamping, the film adheres to the metal surface as a whole Generally speaking, it is necessary to carry out subsequent stamping and other processes on the metal, and the film adhered to the surface makes the metal unable to perform subsequent stamping and other processes

[0004] However, the above-mentioned traditional craft technology is backward, the cost is high, and the effect is not ideal, and the printed patterns or patterns are rough, which cannot really meet the needs of decoration, anti-counterfeiting, etc.
