Accompanying drawing explanation
Fig. 1 is the flow chart of a kind of embodiment of injection moulding process of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are elaborated.It is emphasized that following explanation is only exemplary, instead of in order to limit the scope of the invention and apply.
In some embodiments, a kind of in-mode inserts injection structure comprises optical thin film and is coated in the ink layer on described optical thin film, described optical thin film, described ink layer and the injection mo(u)lding of injection moulding plastic are integrated, and described optical thin film comprises by the higher resin molding of refractive index and the lower resin molding of refractive index is alternately laminated forms stepped construction.The general principle of optical thin film of the present invention is the interference effect utilizing light, when light will produce spe-cial optical effects when the film of different refraction coefficient alternately laminated stepped construction, brings metallic high-matte decoration effect.
In preferred embodiment, the layer continuous print in described stepped construction is alternately distributed at equal intervals, and the thickness of layer is one end of described stepped construction is thin, and the other end is thick.More preferably, the layer in described stepped construction is the waveform of crest and trough interleaved.Described stepped construction is preferably the stepped construction of 800 ~ 1200 layers, and general thickness is 100 ~ 300 μm.More preferably, described stepped construction is the stepped construction of 1000 layers, and general thickness is 200 μm, and average thickness is about 0.2 μm.
In preferred embodiment, the refractive index of the resin molding that described refractive index is higher is 1.7, and the refractive index of the resin molding that described refractive index is lower is 1.6.
Described resin molding can be PETG (PET) film or polymethyl methacrylate film or polycarbonate membrane etc., preferably adopts PET film.
See Fig. 1, in some embodiments, a kind of injection moulding process of in-mode inserts injection structure comprises the following steps:
