Bronzing principle:

The process is mainly the use of thermocompression transfer principle. Hot stamping foil stamping version substrates under the combined pressure contact stamping version has a certain amount of heat due to the heating of the heating plate, anodized aluminum heat hot melt dyeing resin layer and adhesive melting stained resin layer

Adhesive strength decreases, while the special thermal adhesive increase in viscosity after melting, the peeling of the aluminum layer and the anodized aluminum base film is transferred to the substrates, with the pressure dropped, the adhesive rapidly cooled and solidified, the aluminum layer is firmly attached to the substrates on the completion of a stamping process.

Note:

1,small hot stamping machine must choose the different varieties of hot stamping foil. The stamping must master the temperature, pressure, Printing speed tripartite with different stamping material, stamping different area.

2,should be cutting the speed and direction of the master of good tools.

3, hot stamping foil selection of properties suitable for paper, ink (especially black ink), kerosene, composite glue, stamping parts must be kept dry, so as to avoid the the bronzing layer oxidation or damage.

4,General packaging: 64CM × 120M roll of every 10 rolls box; customizable width 64CM, the length 120M or 360m Roll or other specifications.

5,Storage stand up against pressure, moisture, heat, sun, and put in a cool, well-ventilated place.

Determine the elements:

Perfect bronzing effect mainly depends on the temperature, pressure and speed stamping co-ordination of the three levels. Therefore, to control the the bronzing quality should have a good reasonable the bronzing temperature, bronzing pressure and speed stamping. So to create good conditions for bronzing can finally make the bronzing quality guarantee.

The effects of temperature

Temperature has a very important impact on the stamping, the temperature must be controlled within the respective ranges, moderate melting the dyed resin layer and the adhesive, in order to ensure a good transfer on the aluminum layer.

If the temperature is too high, melted over stamping graphic around the anodized aluminum melting off the paste version, while the high temperature will make the anodized aluminum, stained resin and aluminum layer chemical changes, stamping decrease in brightness and loss of metallic luster, even the imprinting appears fog porphyraceous or blistering; However, if the temperature is too low, the melting inadequate, can also cause stamping on or stamping is not strong, the blot is not solid, easy to fall off, or missing pen off program, blot blur.

Environmental impact

The machine should be installed in a dry, good ventilation, light, convenient operation.

The effects of stress

Stamping of the aluminum layer transfer must be completed by pressure affect anodized aluminum adhesion to the size of the stamping pressure. Even if the temperature is right, if the pressure is insufficient, but also can not make hot stamping foil transfer well to the substrates, will produce blot hair virtual flower version; contrary, if the pressure is too large, liner and compression deformation of the substrate is too large, and blot hair is coarse, even adhesion, paste version. Stamping pressure usually should be appropriately adjusted small to reach does not fade, adhesion fastness for guidelines.

Consolidated substrates adjusting the stamping pressure, stamping temperature, vehicle speed, and anodized aluminum itself and other factors. In general, paper and firm, smooth high solid ink printing, and a higher stamping temperature, the case of the slow speed, stamping pressure should be small, on the contrary, it should be a large number. Stamping pressure must be uniform, If you find a local stamping on and floral linen, small pressure is likely here, where flat mat layer of tissue, the pressure balance.

The impact of the stamping pad of the pressure is also larger. Hard liner can be imprinted handsome, applicable to solid, smooth paper, coated paper, glass, paper jam; soft liner, blot coarse, suitable for larger stamping, especially uneven surface paper flatness, smoothness, rough paper.

Installation of hot stamping foil can not be too tight or too loose, too tight handwriting missing pen off program; too loose, illegible, paste version.

Velocity

The contact time of the substrates and hot stamping foil stamping speed actually reflect stamping a direct impact to the stamping fastness. Printing speed is too fast, it will lead to the stamping on or imprinted blur; Printing speed is too slow will affect both stamping quality, but also affect the production efficiency.

Speed, pressure, and temperature in the stamping process mutual restraint, the process parameters are always stamping speed, pressure, temperature in the order determined. First, determine the stamping speed. Normal circumstances, for constant processing does not change easily, and then identify with suitable stamping pressure and hot stamping temperature, this can be simplified operating procedures, and also easy to control the stamping quality.

In addition, the stamping process should also consider whether the substrate, stamping, hot stamping machine, fixture, and pad suitable. Finally, look at the environmental conditions, including the indoor temperature and humidity, the temperature of the substrate, the cleanliness of the indoor air (dust content).
