Embodiment Construction

[0020] The present invention is further described below in conjunction with specific embodiment:

[0021] A production process for a 3D curved surface protective film, comprising the following steps:

[0022] The first step is die-cutting the raw materials, cutting the raw materials into fixed sizes according to the specifications of the mold; after cutting the raw materials, place them according to the front and back sides.

[0023] The second step is hot pressing, tearing off the front and back textured protective film on the surface of the raw material after die-cutting, and then placing it on the bottom of the mold, and hot pressing according to the size of the forming radian; clean it with a dust-free cloth after every hot pressing 10 times mold. After hot pressing, the product should not have reverse deformation, and the hot pressing curved surface and the glass curved surface should be firmly bonded, and there should be no blistering. After hot pressing, the window ar...

Abstract

The invention discloses a process for producing a 3D curved surface protective film, comprising the following steps: S1, raw material die cutting: parting off a raw material to a fixed size according to the specification of a mold; S2, hot pressing; S3, inspecting the quality of semi-finished products obtained in S2, and removing unqualified semi-finished products; S4, punching; S5, inspecting the quality of semi-finished products obtained in S4, and removing unqualified semi-finished products; and S5, packaging the qualified semi-finished products obtained in S5 to get finished 3D protective films. The 3D protective film prepared using the process for producing 3D curved surface protective films not only has the advantages of the ordinary protective film, but also has the unique advantages of the 3D protective film. The 3D protective film of the invention can be designed exquisitely in accordance with the models of mobile phones, fit mobile phones completely, has a perfect and fashionable appearance, is stereoscopic and real, and can achieve a dynamic change effect.

Description

technical field [0001] The invention relates to a method for manufacturing a protective film, in particular to a production process for a 3D curved surface protective film. Background technique [0002] With the rapid development of technology and manufacturing level, mobile phone screens are not only flat, but also begin to develop towards 2.5D and 3D arc-shaped trends, and arc-shaped protective films begin to appear; the traditional 2D flat mobile phone protective film manufacturing process is simply cutting and blanking. 3D mobile phone film is exquisitely designed according to the models of various mobile phones. It completely fits the mobile phone. It has a perfect and fashionable appearance, and has a strong three-dimensional effect. A mobile phone sticker protector that can be seen in a lifelike three-dimensional effect. 3D mobile phone back film is a mobile phone sticker with 3D effect. It is a 3D mobile phone back film and computer sticker with high cost performan...
