Specific embodiment
The present invention provides a kind of method for realizing IML metal-likes by being molded and optics plating, to make the mesh of the present invention
, technical solution and effect it is clearer, clear and definite, the present invention is described in more detail below.It should be appreciated that described herein
Specific embodiment be only used to explain the present invention, be not intended to limit the present invention.
The present invention is using UV transfer embossing treatment technologies, in IML hyaline membranes（PET film piece）Upper extrude is similar to metal processing
Wire drawing or CD textures, then optical coating is carried out to it, pattern and trade mark is realized using printing later, finally using in-mould injection
Molding realizes that IML products have the effect of high metallic texture and gloss.
The present invention by be molded and optics plating come realize IML metal-likes method it include step：
S1, UV transfer embossing processing is carried out to PET film piece；
S2, optical coating processing is carried out to PET film piece；
S3, ink printing treatment is carried out to PET film piece；
S4, the IML products that high metallic texture, high glaze are obtained finally by mold injection.
UV transfer embossing processing is carried out to PET film piece first, makes PET film piece that there is the grain effect similar to metal.So
Optical coating is carried out to the PET film piece afterwards（It is usually metal oxide to plate membrane material, such as magnesium fluoride, titanium dioxide or zirconium oxide
Deng）, there is PET film piece texture and dazzle beautiful metallic luster.PET film piece is made to reach ideal color by ink printing again to imitate
Fruit obtains the IML products with high metallic texture, high glaze finally by mold injection.
Embossing texture can have both been handled at the back side of PET film piece, can also be handled in the front of PET film piece, can be obtained
The characteristics of sub- different IML products of surface light, two kinds of IML products are respectively provided with strong metallic luster.It is noted that embossing exists
The positive IML products of diaphragm have fine and smooth feel simultaneously, have the experience of good sense of touch.
One specific example is as follows：
UV is transferred：The transparent PET diaphragm that thickness is taken to be 0.125mm, removes its surface impurity.Specifically by UV dispensings（UV
Glue）Drop in molding roller mould（Generally drawing pattern or CD lines）Middle levelling treats the glue injection part of PET film piece and roller mould
Divide bonding, row's bubble, place 3-5min at room temperature（Such as 4min）UV glue and PET film piece is allowed fully to merge.Then, UV curing is crossed
Three-dimensional pattern is realized in curing.UV curings built-in temperature must not be higher than 50 DEG C, such as temperature is 45 DEG C, in order to avoid the excessively high PET film of temperature
Piece deforms.
Optical coating：After being cleaned to processed PET film piece, optical coating is carried out.Its condition is：Vacuum drying oven is placed in take out very
Sky is to 0.1Pa, specific available gas（N2Or O2）Displacement is twice.Use purity for 99.99% TiO2Powder transient heating is extremely steamed
Such as 2200 DEG C of temperature is sent out, adjustment plated film time obtains required film layer, and general film layer is 200 ~ 300nm.
Printing treatment：According to product requirement, upper logo is printed successively（Layer）（Ingredient is the ink with mirror effect of Al ions）, primary coat
Oxidant layer, background color oxidant layer, wash-prime coat（Prevent red ink protective layer）And binding agent, every layer of print thickness is at 20 ~ 30 μm.At printing
Reason makes PET film piece have the color effects of accreditation, and ensures that PET film piece preferably can be tied mutually in injection with injected plastics material
It closes, avoids the occurrence of red ink phenomenon.
Diaphragm is cut：The PET film piece handled well is cut spare.
Injection molding：The PET film piece cut is put into injection mold positioning, mold-closing injection.Case material is PC, injection
At 260 DEG C or so, injection time is 3 ~ 4 seconds for temperature control（Such as 3 seconds）, obtain IML final products.
It handles to obtain UV embossing 200 as shown in Figure 1, carrying out transparent PET diaphragm 100 UV transfer embossing：One face has
Wire drawing texture is known as A faces；Another side smooth finish surface is known as B faces.
Embodiment one：A faces are as product external surfaces
Implementation steps：Optical coating --- printing treatment --- diaphragm cutting --- injection molding
It is fine and smooth with metal-like and while gloss, having as shown in Fig. 2, the product surface is matte effect
Sense of touch, the IML products include such as lower floor successively：UV embossing 200, transparent PET diaphragm 100, optical coating 300,（It may include logo
（Layer））, silane coupling agent 400, background color oxidant layer 500, processing oxidant layer 600（Wash-prime coat and adhesive layer）, shell material 700.
Embodiment two：B faces are as product external surfaces
Implementation steps：Optical coating --- printing treatment --- diaphragm cutting --- injection molding
As shown in figure 3, the product have high bright and clean surface, there is strong metal-like and dazzle beautiful texture gloss,
The IML products include such as lower floor successively：Transparent PET diaphragm 100, UV embossing 200, optical coating 300,（It may include logo）, bottom
Apply oxidant layer 400, background color oxidant layer 500, processing oxidant layer 600（Wash-prime coat and adhesive layer）, shell material 700.
Make diaphragm that there is the metal texture of lifelike stereoscopic by the embossing of UV transfer techniques, with reference to optically coated technique, make
Texture has strong reflecting effect to light, so as to which IML product surfaces be made to have strong metal-like and gloss.Embossing is in film
The different application in piece A, B faces can meet to do not share the same light sub- effect the needs of, certain sense of touch demand can also be met.
In conclusion three-dimensional pattern is extruded using UV transfers, and with reference to optics in PET film on piece present invention employs one kind
The mode of plated film so as to which IML products be made to have achieved the effect that high metallic texture, high glaze, is both realized metal-like, is met simultaneously
Texture sense of touch.
It should be understood that the application of the present invention is not limited to the above, it for those of ordinary skills, can
To be improved or converted according to the above description, all these modifications and variations should all belong to the guarantor of appended claims of the present invention
Protect range.
