Embodiment three
Reference picture 10 provides a kind of phone housing processing technology, the difference with embodiment one in the present embodiment to Figure 17
Part is, in the present embodiment, plastic parts is plastic cement center 24, and phone housing also includes metal battery bonnet 21 and upper and lower plastic cement
Ornamental strip 22,23.
Specifically, the phone housing processing technology of the present embodiment comprises the following steps：
The forming step of metal battery bonnet 21, by metal stock extrusion forming and anodized surface processing is carried out, formed
Metal battery bonnet 21；
Upper and lower two plastic cement ornamental strip forming step, plastic-injection mold two plastic cement ornamental strips 22,23, plastic cement dress
The width a2 of panel 22,23 is less than or equal to 4mm；
Plastic parts (i.e. plastic cement center) forming step, injection molding plastic parts (i.e. plastic cement center 24)；
Antenna forming step, in one-level appearance (the i.e. upper and lower end of plastic cement center 24 of plastic parts (i.e. plastic cement center 24)
Appearance) on contoured beam antenna 25 (for example, printed antenna 25), antenna 25 bakees 4 hours by silver paste printing ink under conditions of 100 DEG C
Formed.The thickness (the namely maximum gauge of antenna 25) of antenna 25 is less than or equal to 13um, specifically, in the present embodiment, day
The thickness of the main body of line 25 is less than or equal to 13um, and the thickness of the edge of antenna 25 is less than or equal to 5um, the main body of antenna 25 with
Part between edge is gradually thinning along the direction away from main body；
Coated film forming step, by spraying, polishing, Vacuum Deposition and laser carving technique form coating in one-level appearance
Film, coated film cover the region in addition to antenna 25, thickness in antenna 25 and one-level appearance and are less than or equal to 65um；
