Since the round pressing circle is a line contact, the bubble phenomenon which may exist in the flat pressing bronzing can be completely avoided, and the speed is fast and the quality is good. However, because the bronzing plate and the bottom plate relief are round, the processing is difficult and the cost is high. The heat transfer effect of the circular bronzing plate is not very satisfactory, so the use is not extensive, and often it is long in some large output and high quality. The version of the live, such as cigarette packets, wine bags, health products, etc.
1. Process requirements for three-dimensional bronzing
1. Electrochemical aluminum foil
The electrochemical aluminum foil is generally composed of 4 to 5 layers of different materials, such as a base film layer (polyester film), a release layer, a colored layer (silver anodized aluminum has no colored layer), an aluminum plating layer, and an adhesive layer.
The main functions of each layer are:
The 1 base film layer mainly functions to support the other layers.
The function of the 2 peeling layer is to separate the electrochemical aluminum foil layer from the base layer, which determines the transferability of the electrochemical aluminum layer.
3 The main role of the colored layer is to display the color of the anodized aluminum and protect the underlayer. Common colors are: gold, silver, brown, light blue, black, red, green, etc., among which gold and silver are the two most commonly used.
4 The role of the aluminized layer is to present a metallic luster.
5 The role of the adhesive layer is to bond the hot stamping material.
The adhesive materials constituting the adhesive layer are different, and the adhesiveness is also different. In order to adapt to the different surface properties of different hot stamping materials, the electrochemical aluminum will use different bonding layers to form different types of anodized aluminum.
The hot stamping speed and quality are mainly affected by the peeling layer and the adhesive layer. If these coatings are not sensitive to heat, the hot stamping speed will be reduced accordingly. In the past, due to the limitation of heat transfer speed, the flat stamping speed was lower, which was less than 5,000 sheets per hour. However, some of the world's leading suppliers of anodized aluminum have made the production of anodized aluminum sufficient for the industry. Printing speed requirements, Swiss Bobst hot stamping machine has achieved a hot stamping speed of 7,500 sheets / hour. Since the three-dimensional bronzing forms an embossed pattern, the control of temperature, speed and pressure is different from that of ordinary bronzing. Therefore, the requirements for hot stamping foil are also different from ordinary bronzing. When using hot stamping foil, it should be used for stereo hot stamping. Hot stamping foil, but can not use ordinary hot stamping foil as a three-dimensional hot stamping, otherwise it will produce poor quality or other unexpected phenomenon.
