The Principle Of Bronzing

The process is mainly based on the principle of hot-press transfer. Under the action of combined pressure, the anodized aluminum is in contact with the hot stamping plate and the substrate. The hot stamping plate has a certain amount of heat due to the heating of the electric heating plate. The hot-melt dyed resin layer and adhesive will be melted by the heated anodized aluminum, and the dyed resin layer will be viscous. When the special heat-sensitive adhesive melts, the viscosity increases. The aluminum layer and the anodized aluminum base film are peeled off and transferred to the substrate at the same time. As the pressure is removed, the adhesive quickly cools and solidifies, and the aluminum layer firmly adheres to the substrate. Finish a hot stamping process.

In view of the composition and hot stamping mechanism of anodized aluminum, in order to obtain an ideal hot stamping effect, the anodized aluminum foil used for hot stamping must meet the following requirements: the bottom layer is evenly painted, without obvious color difference, color streaks and stains; primer coating Uniformity, smoothness, whiteness and no impurities, no obvious streaks, sand spots and oxidation; good gloss; strong firmness; high definition; correct model
