What is the working principle of the hot stamping machine ？

The images and texts of the mechanical aluminum stamping can show a strong metallic luster, bright colors and fast fading. In particular, the gold and silver electrolyzed aluminum embellishes the surface of the printed matter with its magnificence and exquisite decoration, enhances the artistry of the printed matter, and plays a prominent propaganda effect of the theme.

Hot stamping machine is to complete the electrochemical aluminum hot stamping equipment, it mainly uses the principle of hot press transfer. Under the action of combined pressure and hot plate, the hot plate has a certain heat due to the heating of the electric plate, the hot aluminum is heated to melt the hot melt dyeing resin layer and adhesive, dyeing resin layer viscosity decreases, and the viscosity increases after the melting of special thermal adhesive, aluminum layer and aluminum base film peel at the same time transfer to the substrate, with the removal of pressure, The adhesive is quickly cooled and solidified, and the aluminum layer is firmly attached to the substrate， to complete the hot stamping process.

From the composition of electrolytic aluminum and hot stamping mechanism, in order to obtain the ideal hot stamping effect, the electrolytic aluminum foil used for hot stamping must meet the following requirements: the bottom layer of uniform coloring, no obvious color difference, color bar and color spot. The base glue coating is uniform, smooth, white without impurities, no obvious stripes, sand spots and oxidation phenomenon, good gloss, strong firmness, high clarity, the correct model.
