DETAILED DESCRIPTION

[0021] The following describes a metal composite card provided by the present invention in detail with reference to the accompanying drawings and specific embodiments. It is also noted that, for the sake of completeness, the following embodiments are best and preferred embodiments, and those skilled in the art may employ alternative implementations for known technologies. Furthermore, the accompanying drawings are intended only to provide a more detailed description of the embodiments and are not intended to limit the present invention.

[0022] Example 1: Figures 1 to 3 As shown, an embodiment of the present invention provides a metal composite card, comprising: a card body 1, the card body 1 including a texture layer 2; a hollow groove 3, opened on the texture layer 2; a coil layer 4, located in the hollow groove 3, for transmitting and receiving wireless signals; an information layer 5, located on one side of the texture layer 2, for displaying card information; an effect display layer 6, located on the texture layer 2, and located on the side away from the information layer 5.

[0023] like Figures 1 to 3 As shown, it also includes: two groups of isolation layers 7, which are respectively located on both sides of the texture layer 2, and the information layer 5 and the effect display layer 6 are respectively installed on one group of isolation layers 7.

[0024] The texture layer 2 is made of metal, and the thickness of the texture layer 2 is between 0.3 and 0.5 mm; and the optimal thickness of the texture layer 2 is 0.4 mm.

[0025] The thickness of the information layer 5 is between 0.1 and 0.3 mm, and the optimal thickness of the information layer 5 is 0.2 mm.

[0026] It should be noted that the card body 1 comprises a texture layer 2, an information layer 5, and an effect display layer 6. An isolation layer 7 is installed on the texture layer 2 on the side where the texture layer 2, information layer 5, and effect display layer 6 contact each other. Specifically, two isolation layers 7 are pre-laminated with the texture layer 2 to form an intermediate texture layer 2 with an antenna, which is then laminated together with the effect display layer 6 and information layer 5 to prevent the visible seam. The coil layer 4 is filled with PVC with an antenna, filling the hollow groove 3. The surface of the information layer 5 can be a PVC card surface with information such as a magnetic stripe, hologram, or signature strip. The effect display layer 6 can be made of materials such as ceramic, veneer, carbon fiber, leather, cloth, paper, glass, sapphire, electroplated metal patches, PVC, PC, and PET. This not only retains the texture and feel of a metal card, but also gives the card a more stable and elegant appearance. This diversity and richness better caters to current customers' pursuit of high-end and personalized products.

[0027] Example 2: Figure 3 As shown, the hollow groove 3 includes an insertion area 8 and an overlapping area 9. The insertion area 8 is used to directly place the coil layer 4, and the overlapping area 9 is used to fix and support the coil layer 4 to improve the flatness of the connection between the texture layer 2 and the coil layer 4; to improve the flatness of the connection between the texture layer 2 and the coil layer 4.

[0028] The insulating layer 7 is made of PET film, and the thickness of the insulating layer 7 is between 0.025 and 0.075 mm.

[0029] It should be noted that the present invention can reduce the performance of this seam by adjusting and optimizing the overlapping method of the PVC with antenna (i.e., coil layer 4) and the intermediate texture layer 2. At this time, the hollow groove 3 is circular. Specifically, the hollow edge of the upper surface of the intermediate texture layer 2 is 5mm and 0.2mm is milled off by CNC equipment. At the same time, the edge of the PVC with the coil is enlarged by 5mm, and this 5mm is also milled thin by 0.2mm. The two can then be embedded and overlapped. This overlapping form can greatly improve the flatness of the connection between the two and effectively reduce the impact of the seam.

[0030] Example 3: In addition, the present invention can change the shape of the hollow area of ​​the intermediate texture layer 2, and at the same time laser etch or electroplate the metal of the intermediate texture layer 2 so that the gaps produced and the etching lines or electroplating lines are integrated with each other to form a beautiful pattern. In this way, after the entire card is pressed together, the pattern designed by us will appear.

[0031] The technical solution provided by the present invention is to first open a user-customized pattern on a texture layer 2 made of metal material, or directly use a universal circle to form a hollow groove 3 of a certain shape, and then fill it with PVC with an antenna of corresponding size, and press a group of isolation layers 7 on both sides of the texture layer 2 to avoid the appearance of this seam. Finally, the texture layer 2, the information layer 5 and the effect display layer 6 are pressed together with a specific glue or film through a specific lamination process to form a complete card body 1.

[0032] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention. While specific details are described in detail in the preferred embodiments of this invention to provide a thorough understanding, those skilled in the art will be able to fully understand this invention without these details. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
