Problems solved by technology

Although the above two treatment processes can achieve a certain degree of three-dimensional effect, the three-dimensional effect is not strong, and process 1 can only process some smooth structures in the process of mold processing, but it cannot process sharp and angular structures, which has obvious advantages. limitation
The output of process 2 is low, it is not suitable for mass production, and the efficiency is low

Embodiment 1

[0024] Embodiment one, (1) select the PET sheet material that thickness is 0.1mm as base material for use, coat UV topcoat on one of the surfaces of this base material, temperature is 17 ℃ when coating UV topcoat, and humidity is 55% , and then put the base material in a curing oven for curing, so that the surface of the base material is hardened to form a UV cured layer, and the thickness of the UV cured layer is 3 μm. (2) On the other surface of the substrate, that is, the symmetrical surface of the UV hardened layer, apply UV topcoat, and die-cast lines on the UV topcoat. The pressure value during die-casting is 10000Pa, and then the substrate is Curing makes the surface of the substrate form a UV texture layer, and the thickness of the UV texture layer is 3 μm. (3) Vacuum sputtering is carried out on the UV texture layer, the target material is titanium oxide, so that a translucent titanium oxide metal layer is formed on the UV texture layer, and the vacuum pressure during...

Embodiment 2

[0025] Embodiment two, (1) select the PET sheet material that thickness is 0.125mm as base material for use, coat UV topcoat on one of the surfaces of this base material, when coating UV topcoat, temperature is 20 ℃, and humidity is 60% , and then put the base material in a curing furnace for curing, so that the surface of the base material is hardened to form a UV hardening layer, and the thickness of the UV hardening layer is 3.5 μm. (2) On the other surface of the substrate, that is, the symmetrical surface of the UV hardened layer, apply UV topcoat, and die-cast lines on the UV topcoat. The pressure value during die-casting is 10000Pa, and then the substrate is Curing causes the surface of the substrate to form a UV textured layer, and the thickness of the UV textured layer is 3.5 μm. (3) Vacuum sputtering is carried out on the UV texture layer, the target material is titanium oxide, so that a translucent titanium oxide metal layer is formed on the UV texture layer, and th...

Abstract

The invention discloses a treatment process of injecting a product in a mold, which comprises the following steps: (1) coating UV finish on one surface of a base material, curing to form a UV hardened layer; (2) coating the UV finish on the other surface of the base material, performing die casting on the UV finish to obtain lines, curing the base material in a curing furnace to form a UV line layer; (3) performing vacuum sputtering of a titanium oxide metal layer on the UV line layer, wherein the light transmittance of the titanium oxide metal layer is 75-80%; (4) printing an ink layer on the titanium oxide metal layer; (5) punching the base material with the printed ink layer to form a sheet material; (6) putting the punched sheet material in a corresponding injection mold to perform injection molding so as to obtain a finished product. The product processed by the treatment process of injecting a product in a mold of the invention has diamond cutting effect with high angularity and high stereoscopic impression, has high wear resistance, and is applicable to mobile phones, panel personal computers, and products with other structures.

Description

technical field [0001] The invention relates to the technical field of surface treatment, in particular to a treatment process for in-mold injection molding products. Background technique [0002] Consumer electronic products such as mobile phones and tablet computers have become more and more popular. On the basis of increasingly powerful functions, the texture of the shell and the three-dimensional effect of the pattern have become more and more indicators for consumers to choose. At present, there are two main ways to make three-dimensional effect on the plastic shell of the product as follows. Process 1. After the texture is injected through the mold. Process 2. After engraving the desired texture on the transparent material, then coating or vacuum sputtering treatment on the texture to make the product produce a three-dimensional pattern effect. Although the above two treatment processes can achieve a certain degree of three-dimensional effect, the three-dimensional e...
