Embodiment Construction

[0008] The present invention will be further described below in conjunction with the accompanying drawings.

[0009] The present invention is carried out according to the following steps: first select a colored transparent resin to inject the product through a mold, and the injection mold makes the color gradient part of the injection molded product into a casing 1 with a gradient thickness (such as figure 1 shown); after the injection molding is completed, spray a primer of a different color from the injection molding product on the surface of the injection molding product with a gradient thickness, such as white, yellow or other bright color primers, and then spray a black primer on the surface of the injection molding product.

[0010] This effect is achieved through the principle of light reflection and refraction. Due to the uneven thickness of the product, the angle of refraction is different for each part.

[0011] The above-mentioned embodiments are only described to ...

Abstract

The invention discloses an injection molding process with a color gradient effect. The injection molding process is realized by the following technical scheme which comprises the following steps of: firstly, transparent resins with colors are selected, and subjected to injection molding by a mold to obtain to a product, wherein the gradient-color part of the injection-molding product is made into a shell with the gradient thickness by the injection-molding mold; and after injection-molding is finished, primers with colors different from an injection-molding object are spayed on the surface of the shell with the gradient thickness of the injection-molding product, and then black primer is sprayed on the surface of the injection-molding product. According to the method provided by the invention, two types of primers are spayed on the surface of the shell with gradient thickness, then the effect of gradient color of the appearance of an injection-molding product can be generated, and different appearance color effects can be generated at different angles.

Description

technical field [0001] The invention relates to the field of injection molding technology, more specifically, relates to an injection molding technology with color gradient effect. Background technique [0002] In today's market, people's requirements for electronic products are not only satisfied with the diversification of functions and other requirements, but the gorgeous appearance and personality display have begun to be loved by consumers of all walks of life. So product appearance has become more and more important. [0003] The casings of existing electronic products basically adopt the injection molding process, but the existing technological means are all uniform color product casings, which cannot meet the diversification requirements of existing products. Contents of the invention [0004] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art and provide an injection molding process with color gradient eff...
