Hot stamping and hot silver are a printing process that uses a certain amount of pressure and temperature to use a template mounted on a hot stamping machine to press the printed matter and hot stamping foil against each other in a short period of time. Or the pigment foil is transferred to the surface of the printed matter according to the image and text of the hot stamping template.

The hot stamping process uses the principle of hot pressure transfer to transfer the aluminum layer in anodized aluminum to the surface of the substrate to form a special metallic effect. Since the main material used for hot stamping is anodized aluminum foil, hot stamping also It's called electrochemical aluminum hot stamping. The most commonly used ones are gold and silver, so they are commonly known as hot stamping, hot stamping, hot stamping gold foil, etc. The hot stamping pattern is clear and beautiful, and the colors are bright and eye-catching.

Hot stamping is an important means of surface decoration of plastic parts, and it is also a commonly used decoration process for household appliances and consumer electronics. It uses a heated hot stamping head to press the metal or paint layer on the hot stamping film onto the surface of the workpiece being processed to achieve the purpose of decoration or marking. There are four basic conditions for the hot stamping process: hot stamping head, hot stamping template, heater and pressure transmission mechanism.

Process advantages

(1) Low plate making cost. Cold stamping does not require expensive metal stamping plates like hot stamping, and it also avoids environmental pollution caused by the stamping plate production process.

(2) High hot stamping accuracy. The resolution of cold stamping is relatively high (basically it can reach the printing resolution). Whether it is stamping small dots and lines, or achieving a hollow effect, its expressive power is very good.

(3) The area of ??hot stamping graphics and texts is larger. Hot stamping can generally only be used to stamp small-area graphics and text such as trademarks and LOGOs, while the width of cold foil is larger, even equivalent to the width of the printing machine, so it is more suitable for hot stamping of large-area graphics and text. .

(4) The applicable base material range is wider. Cold stamping can realize the transfer of cold foil by relying on adhesive and pressure at normal temperature. It does not require special adjustment and control of the stamping temperature like hot stamping. It is not only suitable for stamping ordinary substrates such as paper and cardboard, but also for heating Film materials that are easily deformed can also be used.

(5) It is easier to achieve ironing first and then printing. In the process of hot stamping first and then printing, cold stamping has low operation difficulty, high efficiency and low scrap rate.

(6) Online production can be realized, which is faster and more efficient.
