Hot stamping process is a special printing process without ink, bronzing refers to under certain temperature and pressure of the electrochemical aluminum foil stamping to process on the surface of the substrates, hot stamping machine is hot stamping process equipment. Due to the quality of aluminum foil quality, specifications, model and so on, it will affect the quality of stamping. Therefore, scientific and reasonable selection of electrochemical aluminum foil is a prerequisite for improving the quality of bronzing process.
The process mainly USES the principle of heat transfer. Under the pressure under the action of electrochemical aluminum contact with hot plate, substrates, due to temperature of electric heating plate hot plate has a certain quantity of heat, electrochemical aluminum heat melt hot melt dyeing resin layer and adhesive, colored resin layer viscous force is reduced, and after special thermal melt adhesive viscosity increases, aluminum layer and electrochemical aluminum membrane stripping of transfer printing on the substrates at the same time, as the pressure discharge is divided, adhesive rapid cooling solidification, firmly adhere to the aluminum layer on substrates to complete a hot stamping process.
From the composition and mechanism of hot stamping of electrochemical aluminum, in order to get the ideal effect of hot stamping, hot stamping the electrochemical aluminum foil used must meet the following requirements: the bottom color even, without clear off color, color and color spot; The coating is uniform, smooth and white, without obvious fringe, sand point and oxidation phenomenon. Good gloss; Strong firmness; High definition; The model is correct.
