A kind of practical super thin metal card
[technical field]
The utility model relates to a kind of card, relates in particular to a kind of practical super thin metal card.
[background technology]
Existing metal card production technology, generally adopt copper or stainless steel as base material, more auxiliaryly enter to get final product with etch process, and due to the unicity of technique, the metal card effect that causes this explained hereafter is all to exist with a kind of form basically.And all can't solve in the upper utilization of other noble metals (as gold, silver, platinum, porpezite and alloy type metal thereof), thereby also cause the consumption aspect in metal card market further to be expanded all the time.Traditional metal card, generally occur not possessing utility function as just famous special product in addition.
[utility model content]
The purpose of this utility model is effectively to overcome the deficiency of above-mentioned technology, the practical super thin metal card that provides a kind of sight to combine with practicality, and this practicality super thin metal card is applied in noble metal on card, has expanded the utilization aspect of metal card.
The technical solution of the utility model is achieved in that it includes sandwich layer, its improvements are: described sandwich layer is a square metal card, have a plurality of characters that raise up on metal card, have at least in the upper surface of described metal card and lower surface on the part on a surface and have pattern printed layers; Described metal card and pattern printed layers are packaged in a transparent encapsulated layer, and are packaged with a magnetic stripe or induction chip in the transparent encapsulated layer of described metal card below;
Preferably, four drift angles of described transparent encapsulated layer all have chamfering, and this transparent encapsulated layer adopts the seamless composite package technology of high frequency to realize encapsulation to sandwich layer, and the material of described transparent encapsulated layer be PC, PVC, PET wherein any one;
Preferably, described metal card material is that gold or the materials such as silver or platinum or porpezite are made with hydraulic pressure technique;
Preferably, the thickness of described metal card is 0.001mm, and this metal card is made by pressing process;
Preferably, the upper surface of described transparent encapsulated layer and lower surface are provided with a high wear-resisting coating, and this high wear-resisting coating employing is transparent, material high-wear resistance is made, and is used for the service life of improving described practical super thin metal card.
The beneficial effects of the utility model are: practical super thin metal card of the present utility model, realized the volume production rolling mill practice of 0.003mm sheet material, make very frivolous of metal card, be pressed with pattern and printed layers on metal card, have attractive in appearance and practical two kinds of functions concurrently, utilize simultaneously material still less to make metal card, can make product have more the space of marketing, and broken away from the traditional metal card can only view and admire can't be practical limitation.

[specific embodiment]
The utility model will be further described below in conjunction with drawings and Examples.
With reference to Fig. 1, shown in Figure 2, the utility model has disclosed a kind of practical super thin metal card, it comprises sandwich layer, and this sandwich layer is a square metal card 10, metal card 10 can adopt gold, silver, platinum, porpezite, and wherein any one is made, when metal card 10 is made,, by rolling mill practice, metal card 10 is rolling to the metal card of 0.001mm thickness., by the concavo-convex stamp technology of numerical control, print a plurality of characters that raise up 101 are arranged on metal card 10, for example in Fig. 1, the metal card lower right corner namely is provided with the F7862 of projection, and this character can be used as the reference numbers of card, realizes the functionalization of metal card.In the present embodiment, also has a pattern printed layers 102 on the part of the upper surface of metal card 10, this pattern printed layers 102 can be passed through the color spray printing technology, the landscape of various places, personage etc. are printed to metal card 10, make the form of expression of metal card 10 more various, metal card 10 is also more attractive in appearance.In Fig. 1, Fig. 2, the pattern of metal card 10 and printed layers 102 all are packaged into a transparent encapsulated layer interior 20, with reference to Fig. 2, four drift angles of this transparent encapsulated layer 20 all have chamfering, to prevent that metal card 10 from use scratching human body, transparent encapsulated layer 20 adopts the seamless encapsulation technology that meets of high frequency to realize encapsulation to metal card 10, has solved the difficult problem of super thin metal card encapsulation, and the metal card 10 after encapsulation is more portable; Transparent encapsulated layer 20 can adopt PC, PVC or PET wherein any one, this different materials is all environment-friendly materials, in addition metal card 10 by transparent encapsulated layer 20 encapsulation after, can solve the problem of oxidation of metal.
, with reference to Fig. 3, be another specific embodiment of the present utility model, in the present embodiment, be packaged with a magnetic stripe 30 in the transparent encapsulated layer 20 of the below of metal card 10, certainly, this magnetic stripe 30 can be according to actual conditions, also be replaced by various induction chips, thereby realize different functions.The upper surface of transparent encapsulated layer 20 and lower surface also are provided with a high wear-resisting coating 40, and these high wear-resisting coating 40 employings are transparent, material high-wear resistance is made, and are used for the service life of improving described practical super thin metal card.
Described above is only preferred embodiment of the present utility model, and above-mentioned specific embodiment is not to restriction of the present utility model.In technological thought category of the present utility model, various distortion and modification can appear, the retouching that all those of ordinary skill in the art make according to above description, revise or be equal to replacement, all belong to the scope that the utility model is protected.
