Vacuum coating apparatus, method and product with laser pattern formed on substrate surface

Abstract

The present invention is vacuum coating apparatus, method and product for forming laser pattern on the surface of substrate. Carbonate polymer substrate or acryl substrate is set inside vacuum coating apparatus to vaporize silica and titania coating on the substrate surface. On the coated substrate, one pattern layer is printed in the other surface and one color layer is set on the coating layer. When the product is illuminated with light, the coating layer will refract light to exhibit color change and image refracting visual effect.

Description

technical field [0001] The invention relates to a vacuum coating equipment, method and finished product for forming a laser pattern on the surface of a substrate, in particular to a method for vapor-depositing silicon oxide and titanium oxide on an acrylic substrate or a polycarbonate substrate. A thin film of silicon oxide or titanium oxide is laid on the surface of the above-mentioned substrate, so that light can pass through the film to present a laser light and shadow effect, so that the surface of the substrate can show a good visual effect. Background technique [0002] By the way, the market competition is fierce now. In order to meet the tastes of consumers, mobile phone manufacturers have launched more dazzling and fashionable mobile phones to cater to consumers. [0003] In addition to working hard on the appearance design, metal materials are used instead of traditional plastic materials as the main raw materials for manufacturing mobile phones. Not only can the m...

Problems solved by technology

[0006] Doping metal components in the printing ink can make the printing look like metal, but the current global environmental protection regulations are being revised more and more strictly. Many metal components that are harmful to the environment and the human body can no longer be used. Metallic components are very difficult to recycle, so this production method has its disadvantages

[0007] It is very expensive to make a metal sheet directly on the panel, and now the mobile phone is getting thinner and thinner. The metal fonts made by cutting need to be thinner and thinner, which makes the processing cost even higher and increases the overall cost.

[0008] In addition, metal has the lack of blocking signals or interfering signals. If it is used in communication products, it will cause poor call quality of communication products, and there are defects

[0009] Although the mobile phone made in the above way makes the overall texture more valuable, it still has the above-mentioned shortcomings. Therefore, the current technology still has deficiencies that need to be improved.
