Problems solved by technology

The current metal coating process is to directly spray ink on the outer surface of the stainless steel substrate. It has been verified that the adhesion of the ink layer to the stainless steel substrate is very poor in this metal coating process, and the coverage of defects on the outer surface of the stainless steel is poor.

Abstract

The embodiment of the invention discloses a metal outer surface film lamination method, which comprises the following steps: cleaning a stainless steel substrate, wherein cleaning comprises washing and oil removal; plating a metal film layer on the outer surface of the stainless steel substrate by virtue of a physical vapor deposition method; printing an ink layer on the metal film layer of the stainless steel substrate. Correspondingly, the embodiment of the invention further discloses a metal outer surface film lamination device and a metal housing. According to the embodiment of the invention, the adhesion of the ink layer and the stainless steel substrate can be enhanced, and the defect covering power of the outer surface of the stainless steel substrate can be improved.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a method, a device and a metal casing for coating a metal outer surface. Background technique [0002] At present, in order to improve the aesthetics of the terminal and attract more users, many manufacturers use stainless steel for the casing of the terminal. In order to obtain a more delicate and smooth appearance, the process of metal coating is generally used. At present, the metal coating process is to spray ink directly on the outer surface of the stainless steel substrate. It has been verified that this metal coating process has very poor adhesion between the ink layer and the stainless steel substrate, and poor coverage of defects on the outer surface of the stainless steel. SUMMARY OF THE INVENTION [0003] The invention provides a metal outer surface coating method, device and metal casing, which can enhance the adhesion between an ink layer and a stainles...
