Hot stamping temperature and precautions

Flat hot - silicone mold: 160 ~ 190 degrees

Flat hot - metal mold: 130 ~ 150 degrees

Hot - silicone mold: 170~190 degrees

Hot-metal mold: 160~180 degrees

2, stamping pressure and hot stamping time:

For example, the bronzing paste is printed on the material with a screen plate, then baked at 150 degrees for 5 to 10 minutes and then bronzing; the temperature is 140 to 160° C., the time is 15 to 25 seconds, and the pressure is 4 kg/cm 2 or more (flat hot); temperature 180°C, time 1 second, pressure 4kg/cm2 (hot), etc.

3, hot tips:

When the bronzing machine heats up to the normal temperature, the bronzing paper is still not hot or the peeling is not clean for two reasons:

(1) Gold foil is not suitable for hot stamping the substrate

(2) The hot stamping temperature is not enough, can be raised again temperature test, such as the hot blue light after the hot stamping temperature crossing is too high, can be appropriate cooling and then hot.

4, pay attention to matters:

After hot stamping, do not wipe the hot stamping surface by hand. It is recommended to do a water wash test after 24 hours. The best results are obtained.

The choice of anodized aluminum must be matched with the hot stamping substrate. For example, the popular PVC of Venus No. 400 imported from the United States in the market conditions is not suitable for hot stamping in the ink layer, but the 338 type of aluminum foil imported from Germany has a better combination of fastness. The brand's electro-aluminum also has a model suitable for hot stamping in the ink layer. When users select galvanized aluminum, besides considering the brilliance and price of galvanized aluminum, the hot stamping substrate and its surface state (whether on the printing ink layer or the glazing surface is still hot stamping on the surface of the coating film) are required.
