Specific embodiment
It please refers to shown in Fig. 1 to Fig. 5, that show the specific structures of embodiments of the present invention, herein, to make mobile phone
It is explained for equal electronic equipments protective shell.
A kind of shell polychrome LSR integral forming process comprises the following steps that step (1), obtains PC shell base through injection molding
Body 10；Step (2) prints the first bonding agent in the outer surface of PC housing base 10；Step (3) gets out identification piece, by identification piece
Position pressing where 20 corresponding first bonding agents, identification piece are attached at the outer surface of PC housing base 10；Step (4), in PC shell base
Position of the lateral surface of body 10 other than identification piece 20 applies the second bonding agent；Step (5) is coated with the on PC housing base 10
The side of two bonding agents obtains encapsulated layer 30 through the injection moulding of LSR liquid glue, by the between encapsulated layer 30 and PC housing base 10
Two bonding agent coatings combine fixation；Identification piece is exposed to except encapsulated layer 30；Step (6), using spray sheltering fixture to identification piece 20
Place position is covered, and sprays feel ink layer 40 in the outer surface of encapsulated layer 30.
After the step (1), before step (2), CNC processing, ultrasonic cleaning are carried out to PC housing base 10.The step
Suddenly the pressing in (3) refers to that oil pressure is bonded, and identification piece is molding glue part.
After the step (5), before step (6), in laser carving two dimensional code on encapsulated layer 30.After the step (5), walk
Suddenly before (6), after laser carving two dimensional code, surface treatment processing, for the first time cleaning, encapsulated layer inspection, half are carried out to encapsulated layer
Finished product full inspection.After the step (5), before step (6), before upper spray sheltering fixture, the outer surface of encapsulated layer is carried out clear
It washes.The step (6) after spraying feel ink layer, before not tearing spray sheltering fixture open, carries out sulfur adding treatment, completes sulfur adding treatment
Tear spray sheltering fixture open again afterwards.After tearing spray sheltering fixture open, laser carving roughening treatment is carried out to the inside of PC housing base.In laser carving roughening treatment
Later, it carries out second to clean, roughening checks, scans the two-dimensional code inspection, finished product full inspection.
Fig. 1, Fig. 3 show that encapsulated layer 30 is the situation of double-colored encapsulated layer, and Fig. 4, Fig. 5 show encapsulated layer 30 for monochromatic packet
The situation of glue-line；It is preferred that using double-colored encapsulated layer design, in the step (5), encapsulated layer 30 or double-colored encapsulated layer,
It is divided into the first encapsulated region 31 around identification piece and the second encapsulated area except the first encapsulated region 31 and identification piece 20
Domain 32.First encapsulated region 31, the second encapsulated region 32 color be typically designed to it is not identical, preferably to highlight identification piece,
Identification piece can also be designed as to other colors, in this way, the first encapsulated region, the second encapsulated region and identification piece three are ok
It distinguishes.The area of the mass-tone that first encapsulated area is presented as protective shell, the second encapsulated area is relatively small, for highlighting mark
Position where part.Herein, the apparent height in the first encapsulated region, the second encapsulated region and identification piece can according to needing to change,
Such as: three surface keeps flushing, alternatively, its height is different, convex-concave appearance is presented.Identification piece can be LOGO or other figures
Text etc..
In conclusion design focal point of the invention is, mainly improve contact using feel, be not easy to be scraped by
Damage, identification piece such as LOGO will not be fallen off using pressing, identification piece as printing mark, improve the wear-resistant of mark position
Performance, meanwhile, the highlighting at mark position can be more highlighted in conjunction with encapsulated layer；And it is manufacture craft good stability, controllable
Property is good, is suitable for popularization and application.
The above described is only a preferred embodiment of the present invention, be not intended to limit the scope of the present invention,
Therefore any subtle modifications, equivalent variations and modifications to the above embodiments according to the technical essence of the invention, still
Belong in the range of technical solution of the present invention.
