Problems solved by technology

[0002] There are various sheet patterns for mobile phone casings. Among them, 3D graphics and texts on the mobile phone casing have become fashionable. There are many kinds of multi-color patterns on the surface of the product, but the production process is complicated, and at the same time, it cannot be customized well. The three-dimensional effect of the 3D pattern is not good, and it is easy to wear or scratch and change color

Embodiment Construction

[0019] A printed mobile phone cover and its processing technology in the present invention, the ink is overprinted on the processed sheet material, each color layer is stacked to form a pattern, and then the sheet material is high-pressure formed according to the stretching ratio of the photo material, and then Put the sheet into the injection mold for injection molding. After the injection molding is completed, it becomes a plastic product.

[0020] Described a kind of printed mobile phone cover and its processing technology, production steps are as follows:

[0021] (1) Cutting: First, cut the roll-shaped PET sheet into a square block with a designed size to prepare for the printing process. The thickness of the sheet is 0.125mm-0.188mm.

[0022] (2) Pre-shrinking: Before printing, heat the cut film PET sheet in the oven for 1-5 minutes to minimize the chance of shrinkage.

[0023] (3) Flat printing: According to the required icons and texts, make a film net, and print the ...

Abstract

The invention relates to the technical field of plastic raw material integration and formation, in particular to a printed mobile phone case and a processing technology thereof. The processing technology comprises the steps that ink is overprinted on a processed sheet material, after all colors are superposed, patterns appear, then high pressure formation is conducted on the sheet material according to the stretching proportion of the sheet material, and then the sheet material is placed in an injection mold for injection molding. By means of the processing technology, a product is good in stereo effect, the patterns are vivid, plastic raw materials which are used for bearing the sheet material printing and are subjected to injection molding clamp the ink therein, a rigid shielding layer is formed on the surface, the hardness of the shielding layer reaches 3 H, various decorative patterns can be printed, the surface of a thin membrane can exhibit different textures, therefore a number of different surface textures can be imitated, the stereo-lithography height of three-dimensional patterns can reach 40 mm, the ink is silkscreened on an intermediate layer, the total membrane is arranged on resin, so that letters are not prone to being worn off, the product patterns are difficult to wear, scrape off or discolor, and the stability and durability are achieved.

Description

Technical field: [0001] The invention relates to the technical field of fusion molding of plastic raw materials, in particular to a printed mobile phone cover and its processing technology. Background technique: [0002] There are various sheet patterns for mobile phone casings. Among them, 3D graphics and texts on the mobile phone casing have become fashionable. There are many kinds of multi-color patterns on the surface of the product, but the production process is complicated, and at the same time, it cannot be customized well. The three-dimensional effect of the 3D pattern is not good, and it is easy to wear or scratch and change color. Invention content: [0003] The purpose of the present invention is to provide a printed mobile phone cover and its processing technology in view of the deficiencies in the prior art. The production process is scientific, and it can be customized well. The ink is sandwiched between the material and the plastic material after injection ...
