he main material of the hot stamping is ian waffle, also known as hot foil foil. It consists mainly of two layers of film, that is, polyester film substrate and transfer layer. In the case of stamping, the transfer layer is printed on the entire or part of the surface of the article by heat and pressure. When the punching is completed, the polyester film is torn with the unprinted portion.
The hot stamping process is divided into four steps:
1, hot foil foil and substrate contact.
2, with heat and pressure, heat transfer layer dissolved, transferred to the substrate surface.
3, decompression, polyester film peeling.
4, heat foil foil, printing will be hot.
1, hot foil, roll and single foil two categoriessublimation machine, according to the printing material can be divided into different models. Electroplating and ironing materials between the hot compressibility, speed, temperature, pressure, bronzing plate quality plate and pad version of technology, electric hoist tension adjustment, bronzing machine and many other factors, hot printing suitable for the speed, temperature, pressure important. Various models of Hualv different performance, the appropriate printing materials are also different.
2, hot stamping temperature is too high, hot stamping temperature is too high, will make the stamping marks loss of metallic luster, the edge is not clear or even paste, hot stamping temperature is too low, hot stamping is not hot, hot stamping is not strong or hair.
3, hot stamping pressure, hot stamping pressure is too large, will lead to paste or paste paste, hot stamping pressure is too small, gold foil and the substrate can not be attached, not hot foil part of the cut. Hot stamping foil installation can not be too tight or too loose, when the pen is too tight when the paste is not posted paste paste
4, hot stamping fast, hot stamping speed is actually the reaction hot hot foil and hot foil contact when the direct impact of hot machine, hot stamping too fast, will lead to hot stamping or printing;subli-mate hot stamping speed is too slow, Will affect the quality of stamping, but also affect the production efficiency.
Hot stamping processing speed, pressure, temperature constraints, process parameters are always in accordance with the hot stamping speed, pressure, temperature order to determine. First determine the hot stamping speed, not easy to change. And then find the corresponding hot stamping pressure and hot stamping temperature. This simplifies the operation steps and makes it easy to control the stamping quality.
5, bronzing machine, according to bronzing, bronzing machine can be divided into flat flattened, rounded flat, round pressure three rounds. According to the hot plate version of the location, bronzing machine can be divided into vertical and horizontal.
6, substrate, hot stamping, also known as printing materials, printing materials stamping substrate, including offset paper, coated paper, white cardboard (cardboard) cloth and lacquer cloth, plastic products.
In addition, the resin version can also replace the copper and zinc version of hot stamping, sublimation jewelryas long as the master temperature and pressure, but also good hot products.
