NCVM (Non Conductive Vacuum Metallization) spraying surface treatment process and NCVM product

Abstract

The invention discloses an NCVM (Non Conductive Vacuum Metallization) spraying surface treatment process and an NCVM product. The process comprises the following steps: (1), undercoat spraying: an undercoat is sprayed on a substrate to form an undercoat layer; (2), electroplating: the surface of the undercoat layer is subjected to electroplating treatment to form an electroplating film layer; (3), laser etching oil paint spraying: laser etching oil paint which is convenient for laser etching process is sprayed on the electroplating film to form a laser etching oil paint layer; (4), 3D (Three Dimensional) laser etching: the laser etching oil paint layer is divided into a laser etching area and a non laser etching area, and a laser etching machine is used to perform laser etching process on the laser etching area to form a laser etching layer; (5) finishing coat spraying; (6) 3D laser processing; and (7) curing. By sequentially performing undercoat spraying, electroplating, laser etching oil paint spraying, 3D laser etching, finishing coat spraying, 3D laser processing and curing on the substrate, a shiny surface and matte surface combined object with a handfeel is formed; a shiny surface and a matte surface are combined, so that the appearance of a cell phone is attractive, and a strong visual impact is formed by the shiny surface and the matte surface; and for the use handfeel of the product, the fine and smooth feeling of the shiny surface and the matte surface of the product can be felt.

Description

technical field [0001] The invention relates to the technology in the field of NCVM, in particular to an NCVM spraying surface treatment process and NCVM products. Background technique [0002] Vacuum electroplating, referred to as VM, is the abbreviation of vacuummetalization, which refers to the conversion of metal materials by means of vacuum physics under vacuum conditions, so that metals are converted into particles, deposited or adsorbed on the surface of plastic materials, and form a film, which is what we call coating. Vacuum non-conductive plating, also known as NCVM, is the abbreviation of Nonconductivevacuummetalization in English. NCVM uses thin films such as metal and insulating compounds to make use of the discontinuous characteristics of each phase to obtain a metallic texture in the final appearance. [0003] The NCVM shell combined with the traditional matte surface can only be made of NCVM metal body on one side and painted exterior surface on the other. I...

AI Technical Summary

Problems solved by technology

[0003] The NCVM shell combined with the traditional matte surface can only be made of NCVM metal body on one side and painted exterior surface on the other. It is impossible to intuitively make one surface of the product into two kinds of gloss with touch, that is, one side is NCVM high-gloss surface , on the one hand is the matte surface of the spray area, as consumer electronics products have higher and higher requirements for craftsmanship and appearance

Especially for mobile phone products, consumers pay more and more attention to the beauty and innovation of products, while the shells produced by traditional NCVM technology can no longer meet the needs of consumers
