What Do You Know about Cold Stamping?

With the rapid development of cold stamping technology, it has come to occupy an important place in aluminium printing. This unique and beautiful printing effect is popular with merchants and customers alike as part of the packaging of goods.

Cold stamping differs from traditional hot stamping in terms of aluminum foil, working principle and process flow. The traditional hot stamping process uses an aluminium foil that is pre-coated with a hot melt adhesive on the back, and relies on the pressure of the hot roller to melt the adhesive during stamping, thus enabling the aluminum foil to be transferred. While cold stamping, on the other hand, uses special aluminium, which is not coated with glue on the back. The adhesive is applied directly to the position to be decorated during printing, and then a new technique of cold stamping is used to transfer the aluminium foil. It can be seen that the principle of cold stamping is mainly the use of pressure and special glue to make aluminum and substrate combination.

Compared to the traditional hot stamping process, cold stamping has the following characteristics.

1.Fast printing speed. The fastest cold stamping speed can reach 120 m/min. It can be used on cosmetic bottles to print the customer's desired logo.

2.No heat required. The aluminum foil is firmly bonded on the surface of the printing pattern by applying pressure, and then the aluminum foil is peeled off, so the part of the aluminum foil that needs to be transferred is transferred to the surface of the printing material, and cold stamping printing is realized. So large capacity aluminum bottles are very suitable for cold stamping process to print patterns

3.Economic convenience and cost saving. Due to the use of general flexible printing plate instead of high metal plate roller, cold stamping greatly reduces the production cost of bronzing plate. The cost of cold stamping is only about one tenth of the cost of traditional hot stamping, and can be suitable for small batch production likecompact powder. In addition, energy consumption is reduced because heating rollers are not used.

In addition to the three advantages mentioned above, cold stamping process also has some disadvantages. For example, this process started relatively late and has no high reputation. Some suppliers generally do not use cold stamping process when printing patterns for lipgloss tubes. In addition, the cold stamping process has a large consumption of aluminum, which is generally used in small-scale production like mini compact powder case.

Cold stamping printing solves the difficult process problems in hot stamping printing, and avoids environmental pollution in the process of making metal plates. It can also save a lot of energy, which is the trend of future development. Today, with more and more attention paid to environmental protection, hot stamping has been used in large quantities in Beyaqi. From a small number of defects to perfect application, there is a very perfect production process for hot stamping. In the future, hot stamping in environmental protection and special effects will be more extensive demand and development.
