1. Hot stamping
Bronzing is the use of a certain pressure and temperature, the use of stencils mounted on the stamping machine, so that print and hot stamping press in a short time, the metal foil or color pigment foil according to the hot stamping template requirements, printed in The surface of the hot material is processed.
Since hot stamping is based on gold and silver, it is often called bronzing. This technology is an important process for increasing the visual effects and grades of labels, trademarks, cigarette packets, wine bags and various high-end packaging boxes. From the process can be divided into the first hot after printing and printing after the first hot.
After hot stamping, blank foils are stamped and printed on the surface of blank foils, and then printed on the surface of the aluminum foil layer. They are mostly used for packaging materials that require large area hot stamping. The first printing and then the hot is printed on the printed matter, in the hot stamping part of the hot stamp on the desired pattern, this is a widely used technology.
From the hot stamping method, it can be divided into hot stamping technology and cold stamping technology. Hot stamping technology is the hot stamping process mentioned above that requires a certain temperature and pressure to complete the transfer of galvanized aluminum foil. The cold stamping technology is a process of transferring the electro-aluminum foil to the surface of the packaged printed matter by applying the Uv adhesive to a part where the printed matter needs to be stamped. These two methods have their own characteristics to meet the requirements of different products. .
2. Three-dimensional hot stamping
The three-dimensional bronzing technology is a composite technology combining bronzing technology and embossing and embossing technology. It is the use of corrosion or engraving technology to make the bronzing and embossing graphics into a concave and a convex mold with a positive and a negative mold. Embossing technology once completed the process. This process also completes bronzing and embossing at the same time, which reduces the number of waste products that are not allowed to be processed and overprinted, and increases productivity and product quality.
Since the three-dimensional hot stamping is a combination of hot stamping and embossing and embossing technology, the resulting product is a three-dimensional pattern in an embossed shape and cannot be printed on it. Therefore, it is necessary to adopt the process of printing first and then hot, and at the same time, due to its high precision. And high quality requirements, not suitable for cold stamping technology, but more suitable for hot stamping technology.
