Abstract

The invention relates to a multi-color machining method for the surface of a single part for a vehicle, and belongs to the technical field of surface treatment of vehicle accessories. In order to solve the problems of complex process and poor adhesive force in the prior art, the invention provides the multi-color machining method for the surface of the single part for the vehicle. The method comprises the following steps of: positioning and confirming a plurality of color separation areas needing color decoration on the single part, of which the surface is sprayed with priming paint and colored paint, for the vehicle; selecting transfer carriers with colors consistent with those required by the color separation areas, enabling the color on each transfer carrier to be transferred to a corresponding color layer at each corresponding color separation area through transfer processing, and performing first baking processing; and after finishing the baking, removing a surface film, sprayingvarnish on the surface to form a varnish layer, and carrying out second baking treatment to obtain a corresponding product. According to the method, better adhesive force can be achieved, the processis simplified by directly baking, and the effect of simple process operation is achieved.

Description

technical field [0001] The invention relates to a multi-color processing method for the surface of a single vehicle part, belonging to the technical field of surface treatment of vehicle accessories. Background technique [0002] With the rapid development of my country's auto market and the continuous improvement of the living standards of ordinary consumers, private cars have gradually spread to ordinary families. With the development of the automobile industry, people's aesthetic concepts continue to rise. People's color requirements for the appearance of automobiles are relatively mature for different parts or accessories. When the color requirements are required, most of them are realized by masking and then spraying or bronzing process, but the use of spraying and other processes consumes more raw materials and wastes more, which is not conducive to industrial production, and it is easy to cause pollution in other areas during the spraying process And the outline of t...
