Abstract

A surface treatment method for a composite surface of a basic casing is provided. The composite surface is cooperatively formed by an outer surface and four sidewalls surrounding the outer surface. The surface treatment method includes following steps. A heat transferring film is provided. A printing pattern film is formed on a portion of the heat transferring film via a digital inkjet printing process. The heat transferring film is formed on the composite surface via a vacuum heat transfer process, with edges of the heat transferring film being wrapped around the sidewalls and the printing pattern firm being attached to the outer surface.

First claim

What is claimed is:

1. A surface treatment method for a composite surface of a basic casing, the composite surface cooperatively formed by an outer surface and four sidewalls surrounding the outer surface, the surface treatment method comprising:
providing a heat transferring film;
forming a printing pattern film on a portion of the heat transferring film via a digital inkjet printing process; and
forming the heat transferring film on the composite surface via a vacuum heat transfer process, with edges of the heat transferring film being wrapped around the sidewalls and the printing pattern film being directly attached to the outer surface;
wherein the printing pattern film comprises a basic layer, a printing pattern layer connected to a surface of the basic layer, and a second protective layer connected to a surface of the printing pattern layer facing away from the basic layer, the second protective layer is attached to the portion of the heat transferring film;
wherein the heat transferring film comprises a heat pressing layer and a releasing film layer attached to a surface of the heat pressing layer;
wherein the heat pressing layer comprises a glue layer, a pattern layer, and a first protective layer connected in that order; the releasing film layer is attached to a surface of the first protective layer away from the glue layer;
wherein the second protective layer of the printing pattern film is attached to a surface of the glue layer facing away from the first protective layer.
