Aluminum-plated thermal transfer technology

Aluminum-plated thermal transfer technology

1 Aluminum-plated thermal transfer technology
Aluminum-plated thermal transfer technology is a relatively special thermal transfer technology among the many types of thermal transfer technologies. It is said to be a special transfer technology mainly because the two parts that make up the aluminum-plated thermal transfer technology, whether it is the production of aluminum-plated thermal transfer film or the aluminum-plated thermal transfer processing, have special features.

2 Special features of aluminum-plated thermal transfer technology
So, where are the special features of aluminum-plated thermal transfer technology?

1. Let's first look at the production process of aluminum-coated thermal transfer film:
After the pattern to be printed is made into an electric engraving plate, the printing process of the aluminum-coated thermal transfer film begins. Its production process is mainly divided into the following steps:

1) First, apply a blank base film according to the process requirements of the aluminum-coated thermal transfer film to be produced;

2) Print the transfer film pattern;

3) Vacuum aluminum-coat the printed transfer film;

4) Wash the aluminum-coated transfer film;

5) Dry the aluminum-washed transfer film;

6) Apply the corresponding glue to the dried transfer film;

After re-inspection, striping, and packaging, the aluminum-coated thermal transfer film is completed.

2. The special features of aluminum-coated thermal transfer technology

The third and fourth steps are the special features of the aluminum-coated thermal transfer film during production.

These two processes require the use of a vacuum aluminum plating machine to vacuum aluminum-plated the printed transfer film. The vacuum aluminum plating machine is used to melt and evaporate the metal aluminum wire at high temperature under a high vacuum state, so that the vapor of the aluminum wire is deposited and accumulated on the surface of the transfer film, so that the surface of the transfer film has a metallic luster.

Then the aluminum-plated area outside the pattern is washed away by an aluminum washing machine, so that the metal effect of the pattern is more prominent.

3 Aluminum-plated thermal transfer technology-transfer processing
Let's take a look at the process of aluminum-plated thermal transfer processing. This process is similar to the general transfer process, but because the aluminum-plated thermal transfer film is transferred, the pattern is easily scratched due to the friction of the guide roller of the thermal transfer machine.

Therefore, when transferring the aluminum-plated thermal transfer film, the guide roller of the thermal transfer machine must be synchronized with the thermal transfer film to ensure that the aluminum-plated thermal transfer film is not scratched by the guide roller, thereby affecting the hot stamping effect of the pattern.

4 Application prospects of aluminum-plated thermal transfer technology
Although the application scope of aluminum-plated thermal transfer technology is quite wide, due to the relatively high price of aluminum-plated thermal transfer film, not all products can bear the cost pressure brought by aluminum-plated thermal transfer film. Therefore, at present, only some products with high requirements for product appearance and high grade can use aluminum-plated thermal transfer technology. With the continuous improvement of people's living standards and aesthetic views, I believe that in the future, the use of aluminum-plated thermal transfer technology will have a broader sky.
