The main material for hot stamping is anodized aluminum, also known as hot stamping foil. It consists mainly of two thin layers, a polyester film substrate and a transfer layer. When hot stamping, the transfer layer is imprinted on all or part of the surface of the substrate by the action of heat and pressure. When the stamping is completed, the polyester film is torn off together with the untransferred portion.

The hot stamping process is divided into four steps:

1. The hot stamping foil is in contact with the substrate;

2. By means of heat and pressure, the thermal transfer layer is dissolved and transferred onto the surface of the substrate;

3. Remove the pressure and peel the polyester film;

4. Feed the hot stamping foil and replace it with the printing stamp that will be stamped.

The perfect hot stamping effect depends mainly on the level of temperature, pressure and hot stamping time. In addition, consider whether the substrate, hot stamping machine, hot stamping machine fixture and pad are suitable, and finally study the environmental conditions, including indoor temperature, substrate temperature, indoor air cleanliness (dust content), temperature, etc. .

1. Hot stamping foil, there are two major types of reel and single foil, and the reel can be divided into different models according to the printing materials. The influence of various factors such as ironing property, speed, temperature, pressure, hot stamping quality plate and stencil technology, electro-aluminum tensioning adjustment, and hot stamping machine condition, etc. Hot stamping suitability speed, temperature and pressure are the most important. The performance of various types of anodized aluminum is different, and the suitable printing materials are also different.

2, hot stamping temperature, hot stamping temperature is too high, the hot stamping will lose the metallic luster foaming, the edge is not clear or even the paste, the hot stamping temperature is too low, it will not be hot stamping, hot stamping is not strong or the writing hair.

3, hot stamping pressure, hot stamping pressure is too large, will lead to paste or handwriting paste, hot stamping pressure is too small, hot stamping foil and substrate can not be adhered, and can not cut hot stamping foil stamping parts. The installation of hot stamping foil should not be too tight or too loose. When it is too tight, the writing is short and the stroke is missing. When it is too loose, the writing is not clear.

4, hot stamping speed, hot stamping speed actually reflects the contact time of the substrate and hot stamping foil when the hot stamping, directly affects the hot stamping fastness, hot stamping speed is too fast, it will lead to hot stamping or imprinting The hot stamping speed is too slow, which will affect the quality of hot stamping and affect the production efficiency.

During the hot stamping process, the speed, pressure and temperature are mutually restricted, and the process parameters are always determined in the order of hot stamping speed, pressure and temperature. First determine the hot stamping speed. Under normal circumstances, it is used as a constant processing and is not easily changed. Then find out the appropriate stamping pressure and hot stamping temperature. This simplifies the operating procedure and makes it easy to control the quality of hot stamping.

5, hot stamping machine, according to the hot stamping method, hot stamping machine can be divided into flat flat, round flat, round and round three; according to the position of hot stamping, hot stamping machine can be divided into vertical and horizontal .

6, the substrate, hot stamping is also called the substrate, the printed matter of the hot stamping includes offset paper, coated paper, white cardboard (cardboard) cloth paper and varnish, plastic products.

In addition, the resin plate can also be used in place of the copper-zinc plate for hot stamping. As long as the temperature and pressure are well matched, a good product can be baked. 1), the temperature control is very important, it is directly related to the quality of hot stamping, the temperature is too high, the resin version will also be burnt, the hot stamping foil will also be affected by the temperature, and the hot word will be blurred. The temperature is determined by the quality of the tree. 2) Since the resin plate has toughness, it is not necessary to use too much pressure, and the hot writing will be very clear. 3), the resin plate is best fixed with double-sided tape, this tape does not affect the heat insulation, easy to grasp the temperature.

The hot stamping machine operator should pay attention to the work, hands and feet work synchronously, keep a certain distance to the hot stamping heating plate, so as to avoid accidents, the machine is adjusted, please read the random instruction manual carefully.
