How to mediate the temperature of bronzing machine?

Automatic stamping machine stamping temperature of the general category of 70 ~ 180℃. Once the temperature is clear, it should be maintained as stable as possible from beginning to end to ensure the quality of the same batch of goods is stable. When the same page has a different diagram structure, the selection of the same hot printing temperature usually can not meet the requirements. So how should we adjust the temperature of the bronzing machine?

1. If you want good bronzing effect, it is necessary to have appropriate gold foil with good thermal stability. It is also necessary to cooperate with bronzing machine types, such as flat pressing and rolling type, which have different effects, and then match the elements of temperature, pressure and stay pressing time.

2. Temperature. In the gilding operation, the appropriate temperature is to be able to imprint a clear texture as the standard. The heating plate temperature of flat press stamping machine is about 110℃, and the rolling bronzing machine is 140℃~150℃. The suitable temperature must be found out by test. If the temperature is too high, the bronzing paper will become bad and the lines will be blurred.

3. Stress. The weight of the pressure should conform to the hardness of the material and the texture of the surface. Surface smooth or soft material, can be light pressure, rough or hard, can be heavier pressure. Flat stamping machine is full of synchronous stamping, the line starting point of the air throat machine is line pressing and then converted to flat pressing, rolling machine is similar to offset machine line pressing.

4. Stop pressure time. To short and can be hot printing good effect as the standard, too long time, gold foil and hot printing paper damaged, flash foil will become matte foil.

5. There are to be hot printing pattern with printing pattern set is accurate, when the use of rolling type bronzing machine or large area hot stamping, need to be used for stamping the negative film first reduced to 99.8% to 99.7%, to arrange for the electric plate, so that the electric plate in the heating plate heat expansion.

6. The cost of bronzing depends on what kind of gold foil is used, whether there is a waste of gold foil, in accordance with the sealing, typesetting, quantity, size and so on to measure, so there is no set of standard calculation method to provide a unified price.
