Accompanying drawing explanation
With reference to appended accompanying drawing, to describe embodiments of the invention more fully.But, appended accompanying drawing only for illustration of and elaboration, do not form limitation of the scope of the invention.
Fig. 1 is the process flow diagram of the embodiment of the present invention;
Fig. 2-7 is the device architecture schematic diagrames corresponding to each step in the technological process in Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the present invention is further illustrated, but not as limiting to the invention.
Core concept of the present invention is by utilizing serigraphy to have metallic luster ink at device surface, to realize the appearance with metallic luster, and thus replaces chrome faced technology mode of the prior art.And utilize IMF technique, become structure member.
Below in conjunction with accompanying drawing, technical scheme of the present invention is described in detail.
Step S1, one substrate 11 is provided, and at least one side of this substrate 11 is non-hardened face, as shown in Figure 2, and prebake conditions is carried out to substrate 11, the moisture in substrate 11 is evaporated, and makes the free convergent-divergent of material, thus ensure that the flatness of substrate 11 in subsequent technique process, and then improve the yield of final products.
In above-mentioned technique, the material of substrate 11 can be preferably the plastic material that PC or PET etc. is easy to printed, and the time of prebake conditions and temperature have selected material behavior to determine.
Step S2, prints the upper surface of substrate 11, and printing ink used need have metallic luster, and be Surface Creation one deck ink layer 12 of substrate 11, its structure as shown in Figure 3.
If it is noted that substrate 11 exists hardened face and non-hardened face in this technical process, then ink layer 12 needs to be printed on the non-hardened face of substrate 11.
Preferably, print ink used and need have resistant to elevated temperatures characteristic, ensure that ink layer 12 is in the high-temperature process of subsequent technique, and the change of outward appearance and character does not occur, ensure the presentation quality of final products.
Step S3, carries out baking process to the substrate 11 completing described typography, makes ink layer 12 dry, prevents from subsequent technique, produce red ink phenomenon, ensure the even of ink layer, and then makes the final product appearance obtained neat and artistic.
Preferably, in the baking process of step S3, the temperature process parameter adopted be 60-90 DEG C (such as 65 DEG C, 70 DEG C or 80 DEG C etc.), the time technological parameter adopted be 1-2 hour (such as 1 hour 20 minutes, 1 hour 30 minutes or 1 hour 45 minutes etc.) certainly, also can according to process requirements, suitable increase or reduce above-mentioned two technological parameters, and then prepare the ink layer 21 of uniform in color, stable performance, to meet the demand of technique.
Finally, cool the substrate 11 completing baking, the type of cooling is preferably nature cooling, makes the natural convergent-divergent of substrate 11, avoids effect of stress to make substrate 11 and ink layer 12 that stress deformation occur, the final product appearance obtained of impact.
Simultaneously, preferred further, need electrostatic is set in cooling procedure and dispels equipment, electrostatic is dispelled equipment and is connected with substrate 11, prevent substrate 11 because of Electrostatic Absorption dust, and affect follow-up Shooting Technique, cause coming off because dust two bonds loosely between substrate and injection moulding, and then reduce product yield.
Step S4, carries out moulding process to the substrate completing described baking process, preferably by the mode using Sheet Metal Forming Technology, makes the substrate of plane become original blank 21.As shown in Figure 4, wherein, fresh oil layer of ink 22 covers the front face surface of original blank 21 to its structure.
Re-use clicking technique, the outer sideline judge being Pressing Deformation by original blank 21 goes, and forms the reeded product blank of back side tool, and as shown in Figure 5, product blank 31 and the shaping ink layer 32 of reservation are the shell mechanism of injection molding part.
Step S5, arranges one deck adhesive layer 13 on the concave surface of substrate completing above-mentioned moulding process and clicking technique, to ensure that the moulding that product blank 31 and follow-up Shooting Technique generate can be bonded in one piece securely.
Wherein, the injection moulding particulate material character that the material of adhesive layer 13 is selected by follow-up Shooting Technique determines.
Then, carry out Shooting Technique in the groove of product blank 31, make it form final product, its structure as shown in Figure 7.
Preferably, the injection moulding particulate material that Shooting Technique is selected is PC, ABS, PMMA, PC & ABS.
Step S6, carries out quality inspection to final product.
In sum, in the present invention, adopt serigraphy to reproduce the appearance of plated metal chromium, effectively improve the product cost existed in existing chromium plating technology high, fraction defective is high, influence each other between multiple working procedure and cause the adaptation of product poor, easily the feature such as harm natural environment and human body health, and this technology to have ink film thickness large, color reproducibility is good, resistance to illumination, high temperature resistant, resistance to high humidity, chemically-resistant solvent, expense is lower, meet the features such as parliament of European Union and ROHS.Technically carry out in-mould injection technique at it, the structure member with certain mechanical strength can be formed, and then communication, household electrical appliances electronics, automobile, instrument can be widely used in, instrument, the industry such as medicine equipment and toy.
It should be appreciated by those skilled in the art that those skilled in the art are realizing described change case in conjunction with prior art and above-described embodiment, do not repeat at this.Such change case does not affect flesh and blood of the present invention, does not repeat them here.
Above preferred embodiment of the present invention is described.It is to be appreciated that the present invention is not limited to above-mentioned particular implementation, the equipment wherein do not described in detail to the greatest extent and structure are construed as to be implemented with the common mode in this area; Any those of ordinary skill in the art, do not departing under technical solution of the present invention ambit, the Method and Technology content of above-mentioned announcement all can be utilized to make many possible variations and modification to technical solution of the present invention, or being revised as the Equivalent embodiments of equivalent variations, this does not affect flesh and blood of the present invention.Therefore, every content not departing from technical solution of the present invention, according to technical spirit of the present invention to any simple modification made for any of the above embodiments, equivalent variations and modification, all still belongs in the scope of technical solution of the present invention protection.
