Manufacturing method of integrated film mold

Abstract

The invention discloses a manufacturing method of an integrated film mold. The manufacturing method comprises the following steps that (1), a PC board is adopted as a substrate, and primary silk-screen printing is conducted on the PC board, so that a layer of shading ink is attached to the PC board; (2), secondary silk-screen printing is conducted on the PC board to increase the thickness of the shading ink layer and enhance the shading effect of the shading ink layer, and a film template is obtained; (3), UV glue is applied to the face, printed with the shading ink, of the film template, a height difference area between a non-ink area and an ink area is filled and leveled up, then the UV glue is covered with a PET film, illumination is carried out, after the UV glue is cured, the PET film is separated from the film template, and the UV glue is attached to the film template; (4), a texture female mold and the film template are aligned and punched according to a required mold layout map; and (5), textures on the texture female mold are transferred to the film template, and the film mold is manufactured. The film mold manufactured through the method is high in precision, long in service life and good in shading effect.

Description

technical field [0001] The invention relates to the technical field of making film molds, in particular to a method for making an integrated film mold. Background technique [0002] At present, the decorative texture of the mobile phone camera is directly transferred to the glass through the transfer process, but the transfer mold is mostly a double-layer structure: the texture film is attached to the film sheet. This type of film film mold has the following technical defects: 1. 1. The shading performance of the film sheet is not enough, and there is local light leakage, which leads to a decrease in the yield rate; 2. Due to the limitations of the existing technology, the overall thickness of the mold after the film is attached to the film sheet is generally 0.255mm, and the operation process is easily damaged, which will affect the mold. The service life increases the production cost; 3. The double-layer structure requires a lamination process, which requires high laminati...
