1, temperature: hot stamping temperature has a great impact on the quality of hot stamping. The temperature is too low, resulting in the peeling layer of bronzing paper and adhesive layer melting is not sufficient, hot stamping or hot stamping is not fast. If the temperature is too high, there will be paste version, foaming, metal aluminum oxidation luster and other phenomena. Therefore, according to the type of bronzing paper, hot stamping object (paper, plastic, cloth, leather, etc.), hot stamping pattern and other factors to consider the hot stamping temperature.
2, pressure: hot stamping pressure can not be too large or too small. The pressure is too small, the adhesion between the bronzing layer and the substrate is poor, the bronzing paper is not sufficiently peeled, so that the bronzing blots flower; Too much pressure, will cause paste and substrate surface pressure convex traces. At the same time, hot stamping pressure and hot stamping temperature should be considered together.
3, hot stamping speed: under normal circumstances, hot stamping speed is slow, good glue fastness, but hot stamping speed is too slow, affect the production schedule. Hot stamping speed is too fast, bronzing paper and substrate contact time is short, adhesive layer and peel layer failed to fully melt, resulting in peeling difficulties, and substrate adhesion is not firm. Therefore, hot stamping speed should be appropriate. At the same time, hot stamping speed must be compatible with hot stamping pressure and temperature. Good bronzing paper, suitable for high speed bronzing machine.
