The present embodiment further provides a manufacturing method of the card holder 100, which includes the following steps:

step 1, forming a card support framework 101 by using a metal material.

In some embodiments, the card-holder framework 101 may be formed by powder metallurgy or the like. I.e. by sintering of metal powders. The powder metallurgy process can be specifically divided into the following steps: (1) preparing metal powder, (2) pressing and forming, (3) sintering, and (4) post-processing. The metal material here may be a metal such as Cu, Al, Ag, Fe, Au, Ni, Cr, or an alloy thereof in various forms.

In this example, the card-holding frame 101 was prepared in the following manner.

According to the preset shape configuration of the card holder 100, sheet-shaped sheet metal parts are punched to form a card holder framework 101. The clamping and supporting framework 101 formed by stamping the sheet metal part has the advantages of simple production process and low cost. The molded card cage 101 has a substantially sheet-like structure.

And 2, forming a plastic layer 140 on the card support framework 101 by utilizing in-mold injection molding.

Specifically, the In-mold decoration (IMD) method is a technique of putting the molded card holder frame 101 into an injection mold, injecting a gum on the surface of the card holder frame 101, and integrally curing and molding a resin and a sheet.

In some embodiments, this may be done in particular as follows:

the card support framework 101 is placed in the mold 300, and molten plastic is injected into 3 glue injection points in the length direction of the card support framework 101 at the same time to form the plastic layer 140. The longitudinal direction of the card-holding frame 101 herein refers to the longitudinal extension direction of the first support member 110 and the second support member 120. By arranging more glue injection points, the flowing time of the molten plastic is reduced when the molten plastic enters the mold 300, the instability caused by the change of parameters such as temperature and the like in the flowing process of the molten plastic can be obviously reduced, and the uniformity of the molded plastic layer 140 is improved.

In this embodiment, molten plastic is injected simultaneously into 6 glue injection points along the length direction of the card-holding frame 101 to form the plastic layer 140. Wherein, the 6 glue injection points are symmetrically located at the portions of the mold 300 corresponding to the first support member 110 and the second support member 120, so as to further improve the uniformity of the injection molded plastic layer 140. Specifically, the 6 glue injection points are respectively and correspondingly located in the vicinity of the first clamping groove 161, the second clamping groove 162 and the third clamping groove 163.

In this embodiment, fig. 3 shows a structure of a mold 300 in this embodiment, referring to fig. 3, 6 glue injection ports are formed in the mold 300, the 6 glue injection ports are divided into a first group of glue injection ports 310, a second group of glue injection ports 320 and a third group of glue injection ports 330, and two glue injection ports of each group of glue injection ports are symmetrically arranged on two sides of the mold 300. The card support framework 101 is placed in the mold 300, and the positions of the first injection molding section 111 and the fourth injection molding section 121 correspond to the positions of the first group of glue injection openings 310. The positions of the second injection molding section 112 and the fifth injection molding section 122 correspond to the position of the second group of glue injection ports 320. The positions of the third injection molding section 113 and the sixth injection molding section 123 correspond to the position of the third group of glue injection openings 330. In some embodiments, the first group of injection openings 310 may be aligned with a middle position of the first injection section 111 and the fourth injection section 121. Likewise, the second group of injection openings 320 can be aligned with the middle position of the second injection section 112 and the fifth injection section 122. The third set of injection openings 330 may be aligned with the middle positions of the third injection section 113 and the sixth injection section 123.

During injection molding, the 6 glue injection ports simultaneously inject molten plastics, and the same injection pressure and injection flow are kept, so that the uniformity of the injection molding plastic layers 140 at each position is ensured. The plastic layer 140 and the pressing portion 150 are obtained by pressure maintaining molding after injection.

The in-mold injection molding technology has the following technical advantages:

1. product stability: so that the plastic layer 140 and the pressing portion 150 can produce consistent and standardized correct color register.

2. Product durability: the plastic layer 140 and the pressing portion 150 can have better surface wear resistance and chemical resistance.

3. 3D complex shape design: the application of the excellent extensibility of the film can successfully meet the complex outward-opening design requirements of the required card holder 100.

4. Diversified styles: can create special patterns of metal plating or natural materials according to the requirements of customers.

5. The process is simplified: by means of one-step injection molding, the molding and decoration can be simultaneously achieved, the cost and the working hours can be effectively reduced, and stable production can be provided.

6. The cost and the working hours are reduced: in the IMD process, only one set of mold 300 is needed, unlike other old replacing processes which need to open a plurality of sets of jigs, the manpower and the working hours of one-time operation procedures can be eliminated, and the system cost and the inventory cost are reduced.

In this embodiment, since the pressing portion 150 and the plastic layer 140 are integrally formed in the process of forming the plastic layer 140, the number of manufacturing processes is further reduced, and the manufacturing cost is reduced.

Step 3, after the plastic layer 140 and the pressing portion 150 are formed, the surface of the pressing portion 150 is covered with the decoration layer 170, and the decoration layer 170 may be formed on the surface of the pressing portion 150 by, for example, vacuum deposition, sputtering, or plating.

In this embodiment, the decoration layer 170 is formed by spraying, and the main component of the decoration layer 170 is nickel-chromium alloy. Specifically, the surface of the pressing portion 150 is first degreased and cleaned, and the cleaning liquid may be, for example, alcohol or acetone. Then, the decoration layer 170 is formed by performing a spraying process using an Al electrode, and in some embodiments, before the spraying process using the electrode, the surface of the pressing part 150 is primer-coated, i.e., the depressions on the surface of the pressing part 150 are filled, so that the sprayed decoration layer 170 has a uniform thickness and a more remarkable metallic gloss.

In some embodiments, the decorative layer 170 may not be provided, and the plastic color of the pressing portion 150 is directly reserved and used for exposure. In some embodiments, the decorative layer 170 may be provided with a surface treatment to remove various defects such as impurities and cracks on the surface of the card holder 100.

The card holder 100 provided in this embodiment can be applied to various electronic devices, such as various mobile terminals, e.g., mobile phones, tablet computers, smart watches, and the like. And because the design of the three-card slot 160 is adopted, the multi-card multi-standby function can be realized, and various types of SIM cards can be loaded.
