Bronzing machine is the perfect bronzing effect depends on the level of temperature, pressure and bronzing speed of the three co-ordinated. Therefore, to control the stamping quality, should grasp the good fair gilt temperature, hot stamping pressure and the speed of bronzing. Such as hot stamping to create a good prerequisite for the ultimate in order to make the the bronzing quality assurance.
The influence of temperature
Temperature has a very important impact on the stamping, the temperature must be controlled in the appropriate range, so that the dyed resin layer and adhesive moderate melting, in order to ensure a good transfer of the aluminum layer.
If the temperature is too high melting over-stamping graphic near the anodized aluminum melting off and a paste version of the high temperature will be anodized aluminum, stained resin and aluminum layer chemical changes, and stamping products decrease in brightness and loss of metallic luster imprinting, or even float to the surface fog porphyritic or blistering; However, if the temperature is too low, the melt is not sufficient, can also cause hot stamping or stamping is not strong, imprinting is not solid, easy off, or lack of pen-off program, imprinting Flooding.
Environmental impact
Machine should be installed in a dry, ventilation, good light, to facilitate manipulation.
The effects of stress
Stamping of the aluminum layer transfer will need to complete the pressure, the size of the stamping pressure affect anodized aluminum adhesion. Even if the temperature is right, if the pressure is insufficient, can not make hot stamping foil transfer well to the substrates, will have to blot hair is true that, on such topics as flower version; the contrary, if too much pressure, compression of the pad and the substrate deformation is too large, the imprinting is coarse, and even adhesion, paste version. Usually stamping pressure due emphasis on small, do not fade to achieve good adhesion as a criterion.
Adjustment of stamping pressure to the substrate, stamping temperature, speed and anodized aluminum, and other factors. In general, thick paper knot high, smooth, printing ink, and stamping high temperature, slow speed, the stamping pressure should be smaller, on the contrary, it should be larger. Stamping pressure must be evenly if it is found on local stamping and flowers of hemp, it is likely the pressure here is too small mat layer of tissue in the department's plate, so that the pressure tends to balance.
Stamping pad pressure. Rigid liner can be imprinted delicate, together for the knot, smooth paper, coated paper, glass cardboard; soft pad on the contrary, coarse imprinting, together for larger stamping, surface uneven , paper flatness, smoothness, than the coarse and heavy paper.
And the installation of hot stamping foil can not be too tight or too loose, too tight when handwriting, lack of pen-off program; too loose handwriting unclear, paste version.
The impact of speed
Printing speed actually reflect stamping, the contact time of the substrates with hot stamping foil, directly affect the stamping fastness. Speed ​​through the fast stamping, will lead to stamping or imprinting blur; stamping speed through the slow both will affect the stamping quality, but also affect the efficiency of producing.
Stamping process, speed, pressure, temperature, mutual restraint, and its process parameters always stamping speed, pressure, temperature of the order to determine. First, determine the stamping speed. Under normal circumstances, their constant handling, change is not taken lightly, and then find the corresponding stamping pressure and stamping temperature, this can simplify the manipulation procedures, but also easily control the stamping quality.
In addition, the stamping process should also consider the substrate, stamping, hot stamping, jigs, and whether the appropriate plate. Finally, to study the environmental premise, including the indoor temperature and humidity, substrate temperature, the cleanliness of the indoor air (dust content) and so on.
In short, the bronzing process is a complex technology, these stamping effect of these topics in order to meet the stamping process control.
