The thickness of described metal body is 0.80～5.00mm.
Described micropore is the laser micropore being processed to form on laser engraving or laser marking machine, and some micropores are arranged into array format.Preferably, described micropore be shaped as rectangle, circle, triangle or polygon.
Described metal body at least processes through nanorize at inner surface.
Described plastics are modified plastics, and described modified plastics forms antenna traces through laser laser carving activation processing in the inner side of described metal body.
A kind of manufacture method making described electronic product casing, including:
A point groove of the notch is transversely offered at two ends inside the metal body of molding；
The some micropores penetrating described metal body are formed in the bottom of the described point of groove of the notch；
By injection molding process, the region overlay plastics at least described point groove of the notch place inside described metal body, described filling plastic is in described micropore.
Further:
Described some micropores are formed by laser engraving, and the power of laser engraving is 12W, and speed is 2000mm/s, and frequency is 60KHz.
Before injection mo(u)lding, described metal body at least inner surface is carried out nanorize process.
Described plastics are modified plastics, after injection mo(u)lding, described modified plastics also carry out laser laser carving activation processing, thus form antenna traces in the inner side of described metal body.
Beneficial effects of the present invention:
By new metal body design, bottom is utilized to have point groove of the notch of some micropores, injection-molded plastic in it, eliminate the electromagnetic shielding of all-metal shell structure, it is ensured that stablizing of mobile communication signal, simultaneously, need not cut off with plastic strip with metal-back, without showing plastic strip outside body, thus realizing the metal appearance performance of higher texture, it is not only able to take into account metal appearance texture, the design of product structure part can also be simplified, make product lighter, thin, short, little.It addition, feel is also more comfortable, the grade of high-end electronic product (such as mobile phone) more can be embodied.
Further, use modified plastics to solve the problem that antenna can not be made in nanometer injection moulded shell, on modified plastics, directly do laser laser carving, reduce and connect FPC and shell fragment support.Reduce assembly technology, reduce the cost.
