Manufacturing process of laminated film mold

Abstract

The invention discloses a manufacturing process of a laminated film mold. The manufacturing process of the laminated film mold comprises the following steps of (1) preparing a shading film, namely, coating a photosensitive material on a PET base material, and exposing and developing to obtain the shading film with a required texture pattern; (2) preparing a texture film, namely, applying UV glue on a texture female die substrate, covering the UV glue with a PET film, transferring the required texture on the PET film through transfer printing machine impressing and UV photocuring, and separating the texture female die substrate from the PET film to obtain a PET texture film; (3) laminating the texture surface of the shading film prepared in the step (1) with the non-texture surface of the PET texture film prepared in the step (2), and defoaming and cutting to obtain a semi-finished product of the film mold; and (4) performing PVD coating on the texture surface of the PET texture film ofthe semi-finished product of the film mold to obtain a finished product of the film mold. The film mold has the advantages of being good in toughness, high in precision, high in yield and simple in process.

Description

technical field [0001] The invention relates to the technical field of manufacturing technology of a mobile phone glass camera, in particular to a manufacturing technology of a bonding type film mold. Background technique [0002] At present, the decorative texture of the mobile phone camera is directly transferred to the glass through the transfer printing process, but most of the existing transfer printing molds have an integrated single-layer structure: PC material is used as the substrate, and the required pattern is printed on the substrate by screen printing. Shading ink (6-12um), fill the whole surface with UV glue to fill the ink height, use laser equipment to punch holes in the PC substrate and the texture master, and then set the alignment holes on the substrate and the texture master on the The transfer job is performed on the positioning post. This process has the following technical defects: 1. The precision of screen printing is low, which is ±0.1mm, and the e...

AI Technical Summary

Problems solved by technology

This process has the following technical defects: 1. The precision of screen printing is low, which is ±0.1mm, and the edge of the ink area will appear jagged, and the jagged height > 50um is visible to the naked eye. The printing process is difficult to achieve, and the printing yield is low; 2. 1. It is necessary to make a primer on the entire surface of the PC substrate after printing ink, which is time-sensitive for the second transfer texture operation, generally 12H, and the adhesion of the texture will be affected if the time is too long; 3. Before the transfer, the film and During the punching operation of the master mold, the laser process will cause dirt, scratches and other defects on the product surface, and there will be alignment deviation; 4. During the transfer process, multiple sets of positioning pins will gradually deform the positioning hole, which will affect the product. Accuracy and service life of the texture master mold; 5. After transfer printing, the uncured UV glue needs to be wiped clean. This process is easy to cause defects such as discoloration, dirt, scratches, etc.; 6. The process is complicated and the defect rate is high
