More and more packaging cartons adopt hot stamping process
in the fierce market competition, in order to increase the added value of products and more effectively carry out packaging anti-counterfeiting, more and more packaging cartons adopt hot stamping process. Hot stamping is divided into ordinary hot stamping, cold hot stamping, concave convex hot stamping and holographic hot stamping. The Institute of comprehensive utilization of resources of Zhengzhou Research Institute has organized and formulated detailed experimental schemes, safety operation procedures, hot stamping and other methods. Common hot stamping processes include flat hot stamping and circular hot stamping. Circular hot stamping is a line contact method, which has the characteristics of wide hot stamping substrate, suitable for large-area hot stamping, high hot stamping accuracy and so on
hot stamping does not need to use heated metal plates, but uses printing adhesives to transfer metal foil. Cold stamping process is a promising new process with low cost, energy saving and high production efficiency
concave convex hot stamping (also known as three-dimensional hot stamping) is the use of modern engraving technology to make the upper and lower matching female and male molds. The hot stamping and concave convex pressing process are completed at one time, which improves the production efficiency. The mold made by electric engraving can achieve the three-dimensional relief effect that cannot be achieved by the mold made by general corrosion method through surface transition. The higher the intensity of concave convex hot stamping appears, making the hot stamping and embossing process completed at the same time, reducing the process and waste products caused by inaccurate overprint
holographic identification hot stamping uses computer technology to change the amplitude and frequency of the grating, so that its effect is more brilliant and clearer than the calculated pattern color experimental data file, which can be saved in the way that access often uses the database. If this holographic mark is used as the copy of the original, a large number of holograms will be lost, which can achieve the purpose of anti-counterfeiting. Holographic identification can not only have very good anti-counterfeiting performance, but also make special numbers or words into holographic identification according to customers' needs. It is more and more widely used in the packaging of high-end carton auto parts experimental machine with flexible and diverse control methods
