How does the vacuum coating equipment technology make gradient colors?

The vacuum coating machine can coat a variety of colors, and the most popular color at present is to make gradient colors. At present, many manufacturers are pursuing market demand, and many product colors have been changed to gradient colors. So how does the vacuum coating machine make gradient colors? Zhicheng Vacuum Technology will introduce you in detail:

        The vacuum coating mechanism refers to the use of low-voltage, high-current arc discharge technology under vacuum conditions, using gas discharge to evaporate the target material and ionize both the evaporated material and the gas, and use the acceleration of the electric field to make the evaporated material and gas Its reaction products are deposited on the workpiece.

        To make a gradient color, a baffle (MASK) will be added between the target and the workpiece. The film thickness deposited in the area corresponding to the large MASK area is small, and the film thickness deposited in the small MASK area is large. OPPOR17 has made breakthroughs and innovations in the treatment of cover decoration, with streamer blue and neon purple magic color gradients. After going through a lot of complicated processes, a cover plate can superimpose multiple colors. The body can sensitively respond to changes in light, achieve a smooth color gradient effect, and present a rich and colorful light effect. You can see different colors from different angles. light and shadow effects.

         The gradual color process of vacuum coating machine has entered a hot period. In the fast-growing 3C electronics industry on the market, major brands are fiercely vying for the market, and they are all eager to have a place in the industry. Then, in the face of fast-changing brands, fierce competition in the market environment, and ever-changing consumer needs, only by maintaining our own continuous innovation and standing at the forefront of market and consumer requirements can bold design be invincible. Gradient color can be said to be the popular color of this year. Since the Huawei P20 became popular, everyone has confirmed that gradient color has become a design trend in the past two years.

         At present, whether the back cover of the mobile phone is glass or plastic, the PVD technology of the vacuum coating machine can be used; then let’s talk about the principle of the PVD gradient color of the vacuum coating machine.

There are several main color process options
1. Pure PVD solution (pure dielectric film and non-conductive metal dielectric film)
2. PET coloring material (coating) + UV + PVD
3. Four-color printing + UV + PVD
4. Transparent color varnish+UV+PVD (or silk screen nano metal ink)
5. Raw material dyeing scheme + PVD
6. UV optical grade dyeing scheme + PVD (or silk screen printing)
7. Detailed explanation of gradient color scheme

Dingyi Vacuum Optical Gradient Color Vacuum Coating Machine is specially designed for the coating production of optical thin film products with few layers but requires large capacity and high efficiency. It is suitable for the coating production of glass and plastic optical lenses, spectacle lenses AF and AS films It is also suitable for the preparation of colored optical films for mobile phone windows (glass or plastic) and plastic sheets.
