Embodiment Construction

[0043] see figure 1 and figure 2 , the preferred embodiment of the injection molded product of the present invention is described by taking a housing 10 as an example, such as a mobile phone housing. The casing 10 includes a first decoration layer 12 , a middle layer 14 , and a second decoration layer 16 .

[0044] Both the first decoration layer 12 and the second decoration layer 16 are formed by printing patterns on a film with a certain degree of transparency, and the film can be made of resin, glass, fiber or polymer material. The first decoration layer 12 and the second decoration layer 16 are respectively located on opposite sides of the middle layer 14 . A first pattern 121 is formed on the first decoration layer 12 , and a second pattern 161 is formed on the second decoration layer 16 . The second pattern 161 has the same shape as the first pattern 121 and the position is aligned, that is, in the vertical projection direction of the second decoration layer 16 to th...

Abstract

A molded article includes a first layer, a second layer and a third layer, the first layer and the third layer are transparent, the first layer has first patterns formed thereon, and the third layer has second patterns formed thereon, the second patterns have the same shape and size as the first patterns. The first layer and the third layer are joined to the two opposite sides of the second layer by injection molding, where the first and second patterns align.

Description

technical field [0001] The present invention relates to an injection molding product and its manufacturing method. Background technique [0002] Plastic has the characteristics of light weight, easy manufacture and low cost, and has become a common material for injection molding products such as electronic device housings. When making, the molten plastic is first poured into the cavity of the mold, and the plastic is shaped into the required shell shape according to the shape of the cavity. [0003] However, the appearance and texture of plastic products are not good. In order to improve the appearance of injection molded products, especially the shell, a layer of topcoat is generally sprayed on the surface of the plastic products. However, the surface paint sprayed has poor abrasion resistance. After a long time of use, the housing is easy to cause multiple scratches due to friction, and even the whole piece falls off, which seriously affects the appearance of the housing....
