Perfect bronzing machine bronzing effect mainly depends on the temperature, pressure and bronzing speed with each other. Therefore, to control the quality of bronzing, should grasp the reasonable bronzing temperature, pressure and speed. In this way to create good conditions for bronzing, finally ensure the quality of bronzing.
General bronzing paper material is anodized, so bronzing can also be called anodized hot stamping. But in order to get a good bronzing quality, we still need to pay attention to some aspects, including the selection of bronzing paper. For the bronzing machine, the requirements for bronzing paper are mainly as follows:
Appearance: it mainly refers to the color, brightness, color difference, the allowable range of patchwork width and whether there are some obvious defects.
Hot stamping characteristics: mainly including peeling, the maximum temperature can withstand, and adhesion.
Hot stamping after the characteristics: mainly refers to wear resistance, high temperature resistance and indentation resistance.
Hot stamping temperature, for bronzing process is also a very important aspect, after practice, the best bronzing temperature is 60℃ - 70℃, or 75℃ - 90℃. If the temperature is too low, then you will make anodized aluminum can not be hot stamping to the paper, can not be hot stamping, but the temperature is too high, easy to appear fuzzing phenomenon, or color is too bad, or some other defects.
Version of the roller heating, also gradually phased slow heating, in order to control the surface temperature of the roll, so as to get the best hot stamping temperature, and meet the hot stamping requirements of the bronzing machine.
