SURFACE TREATMENT METHOD FOR PLASTIC SUBSTRATE AND HOUSING USING THE SUBSTRATE

摘要

A surface treatment method for plastic substrate provides an illusion of a three-dimensional weave surface with a high gloss finish. A first shielding sheet with a shielding area, and a plurality of parallel rows of first holes is provided. The first shielding sheet is pasted on a film, and then a first pattern layer is printed on the film, the first pattern layer being translucent. A background layer is formed on the first pattern layer, the color of the background layer being different from the color of the first pattern layer; and the plastic substrate is combined with the film by insert molding, the first pattern layer and the background layer being located between the film and the plastic substrate. A housing manufactured by the method is also provided.

1. A surface treatment method for plastic substrate comprising:
providing a film, the film being transparent or translucent; providing a first shielding sheet, the first shielding sheet having a shielding area, and a plurality of first holes arranged in parallel rows, each two adjacent rows of the first holes being staggered from each other; pasting the first shielding sheet on the film, and then printing a first pattern layer on the film, the first pattern layer being translucent; forming a background layer on the first pattern layer, the color of the background layer being different from the color of the first pattern layer, the first decorative areas overlapping with the background layer to from a plurality of first rectangle patterns having weave appearance; and insert molding a plastic substrate to combine with the film, the first pattern layer and the background layer being located between the film and the plastic substrate.
