Abstract

The invention discloses a surface-treated three-dimensional laser etching process. Ink is sprayed or silk-printed on the back side of a transparent plastic casing; due to the adoption of laser etching, three-dimensional uneven patterns are represented in products, UV (Ultraviolet) primer is prayed on the products and UV or PU (Poly Urethane) colored paint is electroplated on the products; and gradient paint, middle paint and finish paint are sequentially sprayed on the front sides of the products. According to the surface-treated three-dimensional laser etching process disclosed by the invention, a delicate three-dimensional pattern effect on the surface of a coating is realized and patterns are obtained by laser etching.

Description

technical field [0001] The invention relates to the surface treatment of plastic casings, in particular to a three-dimensional three-dimensional laser engraving process for the surface treatment of plastic casings of electronic products. Background technique [0002] Surface treatment is a method of artificially forming a surface layer on the surface of a base material with mechanical, physical and chemical properties different from that of the base. The purpose of surface treatment is to meet the corrosion resistance, wear resistance, decoration or other special functional requirements of the product. For metal castings, our more commonly used surface treatment methods are mechanical grinding, chemical treatment, surface heat treatment, surface spraying, and surface treatment is to clean, sweep, deburr, degrease, and descale the surface of the workpiece. At present, similar plastic surface treatment technologies are: [0003] 1). Electroplating. (Disadvantage: the effect...
