Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
Preferred embodiment one:
Fig. 1 is the structural representation of the material strip of the cell phone rear cover that the present embodiment provides; Fig. 2 is the structural representation of the finished product of the cell phone rear cover that the present embodiment provides.A kind of stainless steel cell phone rear cover processing method, the material strip 1 that described method is at least included in cell phone rear cover carries out the step etching loss of weight, for alleviating the weight of cell phone rear cover and improving the adhesion of in-mould injection, wherein, the material strip 1 of cell phone rear cover selects the stainless steel of 0.4 ~ 0.8mm, material strip 1 etch depth of cell phone rear cover is 0.2 ~ 0.5mm, the material thickness that the material strip 1 of cell phone rear cover is selected can also select thicker or thinner stainless steel material according to the actual requirements, and etch depth also can set according to the thickness of the material strip 1 of cell phone rear cover.
Described method specifically comprises the steps:
Step 1, the material strip 1 choosing the cell phone rear cover that stainless steel is made carry out etching loss of weight, in the present embodiment, preferred etch depth is 0.20mm, etched pattern is multiple triangles be connected to each other, etched pattern close-packed arrays effectively can alleviate the weight of cell phone rear cover, can improve again the adhesion of in-mould injection;
Step 2, the cell phone rear cover semi-finished product obtained in step 1 are carried out punch forming, make the sidewall of cell phone rear cover obtain integrally stretching, add the intensity of bonnet;
Step 3, the cell phone rear cover semi-finished product obtained in step 2 are carried out Digit Control Machine Tool roughing; Be specially: mill out the half-finished side of the cell phone rear cover obtained in step 2, side chamfering by special-purpose milling cutter 3 (as shown in Figure 2), antenna segmentation portion is rough milled etc.;
Step 4, the cell phone rear cover semi-finished product obtained in step 3 being carried out surface treatment, polishing as carried out, polishing minute surface, cleaning etc.;
Step 5, the cell phone rear cover semi-finished product obtained in step 4 are carried out in-mould injection, for the inside of cell phone rear cover is shaping;
Step 6, the cell phone rear cover semi-finished product obtained in step 5 are carried out fine finishining, as carried out refine to the inner side of cell phone rear cover thus reaching design size tolerance;
Step 7, the cell phone rear cover semi-finished product obtained in step 6 are carried out sandblasting or wire drawing;
Step 8, the cell phone rear cover semi-finished product obtained in step 7 are carried out ion film plating or plating, obtain the finished product 2 of cell phone rear cover.
This stainless steel cell phone rear cover processing method by first carrying out the processing of etching loss of weight to material strip before punch forming, because material strip is made up of stainless steel, the weight saving of material strip after the etching, in addition, owing to etching on surface, add metal surface area, the adhesion of in-mould injection and plastic cement can well be improved, and the cell phone rear cover intensity after machine-shaping is increased, manufacturing cost is also reduced owing to eliminating a lot of mach step, cell phone rear cover after machine-shaping is compared with the existing cell phone rear cover be made up of aluminium or plastics, outward appearance has more metal-like, high-end and atmospheric, fashion is generous.
