The principle of Hot Stamping Extrusion Line

Hot stamping machine is a kind of mechanical equipment that completes the hot stamping process. Hot stamping refers to the process of hot stamping electrochemical aluminum foil onto the surface of the substrate under a certain temperature and pressure. The working principle of the hot stamping machine is to use the principle of heat and pressure transfer. Under the action of combined pressure, the anodized aluminum is in contact with the hot stamping plate and the substrate, and the aluminum layer and the anodized aluminum base film are peeled off and transferred to the substrate. Next, let's take a look with the editor. Hot stamping refers to a process in which electrochemical aluminum foil is printed on the surface of a carrier under a certain temperature and pressure. The perfect bronzing effect is determined by the combination of temperature, pressure and speed. Therefore, to ensure the quality of bronzing, it is necessary to master the temperature, pressure and speed of bronzing. Only by creating good conditions for bronzing can the bronzing quality be guaranteed. The hot stamping process mainly uses the principle of hot press transfer to work. The anodized aluminum is in contact with the hot stamping plate and substrate under the action of combined pressure. Due to the heating of the electric heating plate, the hot stamping plate has a certain amount of heat. The heating of the anodized aluminum melts the hot-melt dyed resin layer and adhesive, reducing the viscosity of the dyed resin layer, while the viscosity of the special heat-sensitive adhesive increases after melting, and the aluminum layer The anodized aluminum base film is 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 is firmly attached to the substrate to complete a hot stamping process.
