Hot stamping process of pressure on the role of bronzing technology

Both automatic hot stamping machine and manual hot stamping machine are inseparable from temperature, pressure, speed and other factors. Bronzing technology is mainly the use of hot pressure transfer principle.

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 of hot melt dyeing and melt adhesive resin layer, in this paper, starting from tipping machine dyeing 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, With the removal of pressure, the adhesive quickly cools and solidifies, and the aluminum layer is firmly attached to the substrate to complete a hot stamping process.

From the composition of anodized aluminum and hot stamping mechanism, in order to obtain the ideal hot stamping effect, the anodized aluminum foil used for hot stamping must meet the following requirements: the bottom color uniform, no obvious color difference, color bars and spots; The bottom adhesive coating is uniform, smooth, white and free from impurities, no obvious stripes, sand spots and oxidation phenomenon, good gloss and strong firmness.
