The shell of anodized perfume bottle adopts anodized process

Anodized hot stamping has 6 main points

1.

We must close the assembly plate technology.

Before sticking to the plate, should be with the electric heating device on the bottom metal plate surface and the back of the zinc plate respectively wipe clean, with heat resistant glue solution to the appropriate area of kraft paper evenly brush glue and paste on the back of the plate, then stick to the kraft paper plate with glue solution on the electric heating plate, and press firmly.

When fixing the bottom plate, the filling material should be metal material, such as aluminum strip, empty lead, etc., instead of wood which is easily deformed by heat.

In addition, as a fastening with the mortise plug, also apply iron plate lock, in order to prevent the thermal deformation of the bottom plate displacement caused by overprint.

2.

Should pay attention to control the hot stamping temperature.

For general purposes, hot stamping area, the heating temperature is relatively high.

On the contrary, the electric temperature is lower.

Specific conditions should be based on the actual temperature of the plate and the aluminum foil can withstand the appropriate temperature.

If the temperature is too high hot stamping, products are prone to fog spots, poor brightness and bubbling and other defects.

On the contrary, it will cause hot stamping, hair and other quality defects.

The electric heating temperature can be controlled as appropriate between 120-180℃.

3.

It is necessary to accurately understand the relationship between hot stamping pressure and adhesion fastness of aluminum foil.

When the temperature has reached the appropriate, but the pressure is insufficient, will produce fading, should be carefully adjusted the pressure, so that the hot stamping to achieve the quality requirements of color, adhesion fastness.

On the contrary, there will also be fading, so should pay attention to check the hot stamping temperature, adjust the transformer, in order to better control the desired hot stamping effect of the temperature.

4.

Should be in the ink layer dry, adhere firmly to the case of hot stamping.

When the printing ink layer has not been thoroughly dry, so that the ink layer adhesion is not strong in a hurry to hot stamping, easy to produce pull-off ink layer fault, so hot stamping.

Therefore, background printing ink layer can not be too thick, so as not to cause hot stamping, hair paste and other bad phenomenon.

In addition, it should also be noted that in the background ink layer surface hot stamping, should take due consideration to reduce the hot stamping temperature, in order to make hot stamping effect to achieve the ideal quality.

5.

The difference of the characteristics of anodized aluminum and the points that should be noticed.

How is the performance of anodized aluminum, can be used to rub or use transparent adhesive tape adhesive method to identify.

If the color layer is easy to fall off, it indicates that the anodized is more loose and easy to hot stamping, such anodized is suitable for large area hot stamping.

On the contrary, it is suitable for small and medium - sized plate hot stamping, and suitable for hot stamping when the temperature is low.

The use of anodized should grasp the principle of production first hot stamping to ensure better results.

Its storage period should not exceed two years, and should pay attention to moistureproof, heat proof, pressure proof and sunscreen when stored.

6.

Good technology and process to prevent the failure of hot stamping.

Printing background color, to accurately control the amount of desiccant, prevent excessive amount of drying oil caused by printing ink layer crystal, so that the anodized hot stamping.

To properly grasp the ink layer thickness, as far as possible to achieve deep ink thin printing, that is, the hot stamping when pulling off the ink layer.

When the ink, should try to avoid mixing into non-drying oil, such as oil, kerosene, dry oil and corn flour, so as not to cause hot stamping on the situation, can first wipe with anhydrous alcohol hot stamping surface, to destroy the oil layer or wax, enhance the adhesion of aluminum foil.
