In order to improve the hot stamping process of the full-automatic hot stamping machine in work, we can work faster and better, save resources, and maximize profits by selecting the appropriate hot stamping material, controlling the temperature, and setting the pressure of the hot stamping machine. These factors are decisive factors affecting the quality of hot stamping. Here are some tips on how to improve the hot stamping process of the full-automatic hot stamping machine.
Choose the appropriate material for the automatic hot stamping machine
The material for hot stamping should be dense, high in smoothness and surface strength in order to obtain a good stamping effect and to fully reflect the unique electro-aluminum gloss.
Choose the appropriate electro-aluminum model for the automatic hot stamping machine according to the material
When choosing electro-aluminum, not only should the appropriate color be chosen, but also the corresponding model should be selected according to the different materials. Different models have different performance and range of suitable materials for hot stamping.
Create a good hot stamping plate for the automatic hot stamping machine
Hot stamping plates are generally made of copper plates, zinc plates and resin plates. Copper plates are the best, zinc plates are moderate, and resin plates are slightly worse. Therefore, for fine hot stamping, copper plates should be used as much as possible. The surface of the hot stamping plate should be smooth, the graphics and lines should be clear, the edges should be smooth, and there should be no roughness or burrs.
Control the hot stamping temperature of the automatic hot stamping machine
The hot stamping temperature of the full-automatic hot stamping machine must not be lower than the lower limit of the temperature resistance range of the electro-aluminum, which is the minimum temperature required to melt the adhesive layer of the electro-aluminum. Generally, the electric heating temperature should be adjusted between 80-180℃, and for larger hot stamping areas, the electric heating temperature should be relatively higher; conversely, it should be lower. The specific situation should be determined according to the actual temperature of the plate, electro-aluminum type, graphics, and many other factors. Usually, the most suitable temperature should be found through a trial hot stamping, and the standard should be the lowest temperature that can achieve clear graphics and lines.
Reasonably control the hot stamping pressure of the automatic hot stamping machine
The hot stamping pressure is closely related to the adhesive force of the electro-aluminum. Even if the temperature is appropriate, if the pressure is insufficient, the electro-aluminum cannot be firmly adhered to the material, or it may produce color dropping or blurred prints, etc.; conversely, if the pressure is too high, the compression deformation of the pad and the material will be too large, and it may result in a blurry prints or a rough outline. Therefore, the hot stamping pressure should be carefully adjusted, and the hot stamping pressure must be uniform.
Maintain a constant hot stamping speed for the automatic hot stamping machine
Contact time and stamping firmness are directly proportional under certain conditions, and the hot stamping speed determines the contact time between the electro-aluminum and the material. If the hot stamping speed of the full-automatic hot stamping machine is slow, the contact time between the electro-aluminum and the material is long, and the bonding is relatively firm, which is beneficial to hot stamping. On the other hand, if the hot stamping speed is fast, the contact time of the electro-aluminum with the material is short, and the hot-melt organosilicon resin layer and adhesive have not completely melted, which will result in no prints or blurred prints.
