Spray coating method for realizing high-smoothness appearance on surface of complicated mold patterns

Abstract

The invention discloses a spray coating method for realizing the high-smoothness appearance on the surface of complicated mold patterns. The method comprises the following steps that A, materials with veins are subjected to primer layer spray coating and drying; B, the primer layer is subjected to colored paint layer spray coating and drying; C, the colored paint layer is subjected to transparent middle paint layer and drying; D, the transparent middle paint layer is subjected to finish paint layer spray coating and curing, and smooth products with different luster are obtained. Through the method provided by the invention, printing plane regions do not need to be reserved, the pattern continuity is ensured, and the printing on the complicated mold patterns in a certain depth is realized; the high-smooth product appearance effect is obtained under the conditions of not increasing the cost and not changing the mold patterns; and the requirement of customers on different luster effects of the product appearance is met.

Description

technical field [0001] The invention relates to the technical field of mold surface treatment, in particular to a spraying method for realizing a high-gloss and clean appearance on the surface of a complex mold pattern. Background technique [0002] Under the premise that the cost of electronic products remains unchanged, in order to pursue the visual beauty of the appearance and improve the appearance effect, some mold texture designs are often made on the casing. [0003] At present, the common processing method on the market is mold texture design + injection molding + spraying process. The products produced are generally matte products with concave and convex handles, and the surface gloss is single, which is difficult to meet the needs of some high-gloss appearance products. [0004] And on the concave-convex texture, printing is limited by technology. For general electronic products, it is necessary to consider the later printing area and reserve the printing area in ...
