Description
Technical field
The utility model is related to a kind of cell phone back cover.
Background technology
Current cell phone back cover mostly using hardening PET base material, be attached with PET base material successively printing ink layer,
Background color layer, UV glues and glass mat, eventually through carving milling shaping.The defect of this cell phone back cover is：Make work
Skill is complicated, needs using UV glues, come certain thickness glass mat of fitting, to strengthen the thickness of cell phone back cover, and to fit
Efficiency be than relatively low, and easily to produce that product warps, surface produces the problem of sags and crests.Additionally, the semi-finished product after laminating
Need to carve milling shaping, working (machining) efficiency is relatively low, especially complicated structure, such as the loudspeaker pore structure with porous is even more so.
Select in the material of PET base material, be typically chosen high rigidity PET of 0.188mm thickness, the surface of this material is hard
Degree is low, and its pencil hardness can only achieve 2-3H under the loading of 750g power, and especially material hardness was being manufactured when 3H
Easily crack in journey.
