Holographic hot stamping technology is divided into continuous pattern hot stamping and independent pattern hot stamping according to the characteristics of holographic pattern logo. Independent pattern hot stamping, also known as holographic positioning hot stamping technology, has not been applied for a long time and belongs to a relatively new high-tech. The key material used for the holographic anodized aluminum is difficult to produce and the process is extremely complex.

Holographic anodized aluminum is produced by manufacturers using spatial frequency coding based on the principle of laser interference. The holographic pattern marks are regularly arranged on the anodized aluminum, and there is an alignment cursor beside each pattern. Its working principle is that the laser electronic eye in the machine equipment positioning and recognition system feeds the information back to the equipment information processing center (onboard computer) by illuminating the cursor, and then the computer sends the jump distance command to the jump motor to achieve Positioning.
Holographic anodized aluminum and electromechanical equipment are directly related to the accuracy of holographic positioning, which not only involves anti-counterfeiting, but also affects the aesthetics of the product. Strictly speaking, the patterns of holographic anodized aluminum must be equidistant. Since the production of anodized aluminum inevitably produces errors, as the number of patterns increases, the errors are constantly quantified. , Which will affect the accuracy of positioning. The positioning accuracy of the machine equipment positioning system also has the same important influence on the holographic positioning accuracy. Holographic positioning requires that the device has a high positioning accuracy, which is generally required to be controlled within 0.2 mm; the running speed of the device should also be moderate, and too fast or too slow will cause deviations in positioning.
