How does vacuum coating equipment make gradient colors?

Vacuum coating equipment refers to the use of low-voltage, high-current arc discharge technology under vacuum conditions, using gas discharge to evaporate the target and ionizing the evaporated material and gas, and using the acceleration of the electric field to make the evaporated material and gas. Its reaction products are deposited on the workpiece. For gradient color, a baffle plate (MASK) will be added between the target and the workpiece. The area corresponding to the larger MASK will have less film thickness, and the area with smaller MASK will have more film thickness. OPPO R17 breaks through innovation in the processing of cover decoration, with streamer blue and neon purple magic color gradient. After a cover plate has undergone many complex processes, it can achieve a variety of colors superimposed. The body can sensitively sense changes in light, achieve a smooth color gradient effect, and present a variety of light-sensing effects, which can be seen from different angles. light and shadow effects.

The gradation process of vacuum coating equipment has entered a hot period. In the rapidly developing 3C electronics industry on the market, major brands are fiercely vying for the market, all eager to have a place in the industry. Then, in the face of fast-changing brands, fiercely competitive market environment, and changing consumer demands, only by maintaining our own continuous innovation, standing at the forefront of market and consumer requirements, and bold design can we be invincible.

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)
