Therefore, the IML molded product 10 has a metallic appearance as shown in FIG. In other words, the IML molded product 10 has improved design (that is, design) of the IML molded product 10 due to the aesthetic appearance obtained from the metal layer. As a result, the IML molded product 10 can give a high-class feeling to the portable terminal to which the IML molded product 10 is attached.

  As shown in FIG. 1, the IML molded product 10 includes a resin layer 16 as a base material and an IML film 17 bonded to the resin layer 16.

  The IML film 17 is a film for insert, decorates the surface of the resin layer 16 and improves the design.

  In the IML molded product 10 shown in FIG. 1, the side portion 10b is bent at a right angle with respect to the flat portion 10a, but is not particularly limited to a right angle, and the angle depends on the design of the mobile terminal. It can be changed as appropriate. For the safety of the user, as shown in FIG. 2, the side portion 10b is actually bent with a certain degree of curvature with respect to the flat portion 10a. Furthermore, the flat portion 10a may be curved or uneven as appropriate according to the design.

  The hard coat layer 11 is a layer that functions as a protective layer of the IML molded product 10. The hard coat layer 11 is made of a transparent resin material, for example, an ultraviolet effect type resin material.

  The film substrate 12 is a substrate serving as a base of the IML film 17. The film base 12 is a film made of a transparent resin material, and is made of, for example, PET (polyethylene terephthalate) or PC (polycarbonate). The thickness of the film substrate 12 is about 75 μm or more and 125 μm or less.

  The metal layer 13 has a metallic appearance to the IML molded product 10 and aesthetically decorates the appearance of the IML molded product 10. That is, the metal layer 13 improves the design of the IML molded product 10.

Incidentally, the constituent material of the metal layer 13 may be made of a metal material having not limited to a metal material mainly composed of SiO 2, TiO 2, ZrO 2 or the like, general optical properties (translucent) .

  The metal layer 13 is in contact with the film substrate 12. As an example, the metal layer 13 is formed by vapor deposition. For this reason, the metal layer 13 can also be called a vapor deposition layer.

  The ink layer (first layer) 14 is for coloring the IML molded product 10. The ink layer 14 is made of a colored resin material, and is made of, for example, an acrylic paint.

  The ink layer 14 is directly laminated on the metal layer 13 while the metal layer 13 is interposed between the ink layer 14 and the film substrate 12. As an example, the ink layer 14 is formed by printing.

  The adhesive layer 15 is a binder layer for bonding the IML film 17 and the resin layer 16 together. The adhesive layer 15 is indirectly laminated on the metal layer 13 while interposing the metal layer 13 between the adhesive layer 15 and the film substrate 12. The constituent material of the adhesive layer 15 is not particularly limited, and a general material can be used. The adhesive layer 15 is in contact with the ink layer 14.

  The resin layer 16 is a resin layer serving as a base material of the IML molded product 10. The constituent material of the resin layer 16 is not particularly limited, and can be made of a general resin material having a hardness to be a base material. The resin layer 16 can be composed of, for example, PC (polycarbonate), polymethacryl sanmethyl, or the like.

  The resin layer 16 is indirectly laminated on the metal layer 13 while the metal layer 13 is interposed between the resin layer 16 and the film substrate 12. As an example, the resin layer 16 is formed by injection.

  An end surface 10 e along the thickness direction of the IML molded product 10, which is the tip of the side portion 10 b of the IML molded product 10, has a hard coat layer 11, a film substrate 12, an ink layer 14, an adhesive layer 15, and a resin layer 16. Each end face is composed.

  That is, among the layers constituting the IML molded product 10, the end surfaces along the thickness direction of the hard coat layer 11, the film substrate 12, the ink layer 14, the adhesive layer 15, and the resin layer 16 are the IML molded product 10. Since it is exposed to the outside, the interface between each layer is also exposed. In FIG. 1, the end face 10e is parallel to the X axis.

  On the other hand, the end surface 13e along the thickness direction of the metal layer 13 is disposed inside the IML molded product 10, and the end surface 13e and the boundary surface between the metal layer 13 and the film base 12 are formed on the IML molded product 10. It is configured not to be exposed to the outside. Note that the end face 13 e can also be expressed as an end face that defines the thickness of the metal layer 13. In FIG. 1, the end surface 13e is parallel to the X axis.

  Thus, in the IML molded product 10, the boundary surface between the metal layer 13 and the film base 12 is covered with the film base 12, the ink layer 14, and the end (second layer) 14e of the ink layer 14. Thus, the exposure is prevented. For this reason, for example, in the process of inspecting the adhesion of each layer of the IML molded product 10 such as a hot water test, it is possible to prevent the occurrence of a defect such that the boundary between the metal layer 13 and the ink layer 14 is peeled off.

  In the present embodiment, the ink layer 14 is used as a layer laminated on the lower layer of the metal layer 13, but the present invention is not limited to this including the end portion 14e. The lower layer of the metal layer 13 may be a UV resin layer, a binder layer, or another layer instead of the ink layer 14.

  Here, the boundary surfaces of the hard coat layer 11, the film base 12, the ink layer 14, the adhesive layer 15, and the resin layer 16 are exposed as end faces 10e, but the hard coat layer 11, the film base 12, Since the ink layer 14, the adhesive layer 15, and the resin layer 16 are all made of a resin material and have good adhesion, adhesion failure does not occur in the process of inspecting adhesion such as the hot water test.

  The end portion 14e of the ink layer 14 can also be expressed as being bent from the lower layer side to the upper layer side of the metal layer 13. The leading end surface 14 f of the bent end portion 14 e of the ink layer 14 is in contact with the back surface of the film substrate 12. As a result, the end surface 13 e of the metal layer 13 and the boundary surface between the metal layer 13 and the film substrate 12 are covered with the end portion 14 e of the ink layer 14.

  Furthermore, the end portion 14e of the ink layer 14 can also be expressed as a region where the film thickness of the ink layer 14 is increased.

(Method for producing IML molded product 10)
Next, the manufacturing process of the IML molded product 10 will be described with reference to FIGS. First, the manufacturing process of a sheet-like IML film is demonstrated using FIG.

  FIG. 3 is a diagram for explaining each step of manufacturing the IML film.

  In FIG. 3, the upper surface of each layer in FIG. 3 is referred to as the front surface, and the lower surface is referred to as the back surface.

  As shown to (a) of FIG. 3, the film base material 22 used as the film base material 12 of the IML film 17 is prepared first. As the film substrate 22, for example, a regular film or a roll film made of PET or PC and having an area larger than that of the film substrate 12 is used.

  Next, as shown in FIG. 3B, for example, an ultraviolet curable resin material is applied to the surface of the film substrate 22 and cured by ultraviolet rays. Thereby, the hard coat layer 21 is formed on the surface of the film substrate 22.

Then, as shown in FIG. 3C, for example, SiO 2 , TiO 2 , ZrO 2, or the like as a main component is formed on the back surface of the film base material 22 opposite to the surface on which the hard coat layer 21 is formed. A transparent metal material is vapor-deposited (metal vapor deposition step). Thereby, the metal layer 23 is formed on the back surface of the film substrate 22 so as to be in contact with the film substrate 22.

  Next, the metal layer 23 formed on the back surface of the film substrate 22 is masked (masking process), and further subjected to an etching process (etching process).

  Thereby, as shown in (d) of FIG. 3, the metal layer 23a is formed in the back surface of the film base material 22 by removing an unnecessary part among the metal layers 23. FIG. Thus, the end surface along the thickness direction of the metal layer 23 a is formed so as to be disposed inside the IML film 17.

  Then, as shown in FIG. 3E, the acrylic coating material is silk-printed on the back surface of the film base 22 while covering the back surface of the exposed metal layer 23a (printing process). Thereby, the ink layer 24 is formed.

  Next, as shown in FIG. 3 (f), an adhesive layer 25 is formed on the back surface of the ink layer 24 opposite to the surface on which the metal layer 23a is formed by printing such as silk printing. .

  Thereby, the sheet-like IML film 20 is completed.

  Next, the IML molded product 10 is manufactured using the sheet-like IML film 20 with reference to FIG.

  FIG. 4 is a diagram for explaining a manufacturing process of an IML film and an IML molded product.

  As shown in FIG. 4A, the sheet-like IML film 20 is inserted between the lower mold 31 and the upper mold 32 and pressed by the lower mold 31 and the upper mold 32. Is press-molded (molding process (forming process)).

  Thereby, a plurality of flat portions and bent portions bent from the flat portions are formed on the sheet-like IML film 20 in accordance with the shape of the actual product. That is, the sheet-like IML film 20 has a shape in which a plurality of IML films 17 are continuously arranged.

  Next, as shown in FIG. 4B, the molded sheet-like IML film 20 is cut according to the product size (cutting process). As a result, the IML film 17 having the product size and the product shape is formed.

  Then, as shown in FIG. 4C, the IML film 17 is inserted between the molds 35 and 36. Then, injection molding is performed by injecting and solidifying a molten resin material 16a such as PC or polymethacryl sanmethyl on the back surface side of the adhesive layer 15 (molding process. Thereby, a resin layer is formed on the back surface of the adhesive layer 15. 16 is formed.

  4D, the IML molded product 10 in which the IML film 17 is bonded to the surface of the resin layer 16 is completed by being taken out from the molds 35 and 36.

(Adhesion inspection process)
Next, the process for inspecting the adhesiveness of the IML molded product 10 is demonstrated using FIG. FIG. 5 is a diagram illustrating a state of a process for inspecting the adhesion of the IML molded product 10.

  As shown in FIG. 5, the completed IML molded product 10 is inspected for adhesion of each layer in a process for inspecting adhesion before being shipped as a product. Here, it demonstrates as what performs a warm water test as a method of test | inspecting adhesiveness. Although a test other than the warm water test may be performed as the adhesion test, the warm water test is preferably performed because the warm water test is the most severe test.

  As shown in FIG. 5, hot water 38 is stored in the container 37. The IML molded product 10 is sufficiently submerged in the warm water 38. The temperature of the hot water 38 is about 60 ° as an example, and the IML molded product 10 is immersed in the hot water 38 for several hours.

  For this reason, the boundary surfaces of the end surfaces of the hard coat layer 11, the film base 12, the ink layer 14, the adhesive layer 15, and the resin layer 16, which are the end surfaces constituting the end surface 10e of the IML molded product 10, are long with the hot water 38.

  However, since the adhesion between the hard coat layer 11, the film base 12, the ink layer 14, the adhesive layer 15, and the resin layer 16 is good, no peeling defect occurs.

  On the other hand, among the layers constituting the IML molded product 10, the metal layer 13 and the film substrate 12 are only adhered by vapor deposition, and therefore the adhesion is poor compared to the adhesion between other layers.

  However, in the IML molded product 10, the end surface 13 e of the metal layer 13 is disposed inside the IML molded product 10, and the boundary surface between the metal layer 13 and the film base 12 is the end of the film base 12 and the ink layer. It is covered with the portion 14 e and the ink layer 14, and is configured not to be exposed to the outside of the IML molded product 10.

  For this reason, the hot water 38 does not erode on the boundary surface between the metal layer 13 and the film substrate 12, and the metal layer 13 and the film substrate 12 can be prevented from peeling off.

(Modification)
Next, a modified example will be described.

  FIG. 6A is a cross-sectional view illustrating a first modification of the IML molded product 10 according to the present embodiment, and FIG. 6B is a cross-sectional view illustrating a second modification of the IML molded product 10.

  The IML molded product 10 may be configured so that the boundary surface between the metal layer 13 and the film substrate 12 is not exposed to the outside.

  The IML molded product 40 in FIG. 6A is different from the IML molded product 10 in that an IML film 47 is provided instead of the IML film 17. The IML film 47 is different in that the film substrate 42 is provided instead of the film substrate 12.

  An end portion (second layer) 42 e of the film base (film layer) 42 in which the metal layer 13 is directly laminated on the lower layer is bent in a direction along the end surface 13 e of the metal layer 13. The bent end surface 42f of the end portion 42e is in contact with the surface of the ink layer 14 laminated on the lower layer of the metal layer 13.

  In other words, the end portion 42e can also be expressed as connecting the film base material 42 and the ink layer 14 together.

  In this manner, the IML molded product 40 is prevented from being exposed to the outside because the boundary surface between the metal layer 13 and the film base 42 is covered with the end 42e of the film base 42.

  Moreover, the edge part 42e can also be expressed as an area | region where the film thickness is thick among the film base materials 42. FIG.

  In FIG. 6A, the end portion of the ink layer 14 is not bent, and the end surface of the ink layer 14 constitutes the end surface 40e of the IML molded product 40 and is exposed to the outside.

  The IML molded product 50 in FIG. 6B is different from the IML molded product 10 in that a resin layer 56 is provided instead of the resin layer 16.

  An end portion (second layer) 56e of a resin layer (first layer) 56 indirectly laminated on the lower layer of the metal layer 13 via another layer is a direction along the end surface 13e of the metal layer 13 Bent in the (X direction). And the surface 56f which the edge part 56e bend | covers has covered the end surface of the film base material 12 laminated | stacked on the end surface 13e of the metal layer 13, and the upper layer of the metal layer 13. FIG.

  Moreover, in the structure demonstrated in FIG. 1, FIG. 6 (a), although the height of the end surface 13e of the metal layer 13 was different from the height of the end surface of another layer, IML molded product 50 of FIG.6 (b). Then, the height of the end surface 13e of the metal layer 13 is the same height as the end surfaces of the hard coat layer 11, the film substrate 12, the ink layer 14, and the adhesive layer 15, and is in the same plane.

  The surface 56f of the bent end portion 56e of the resin layer 56 covers the end surfaces of the hard coat layer 11, the film base 12, the metal layer 13, the ink layer 14, and the adhesive layer 15.

  That is, the end surface 50 e of the IML molded product 50 is the back surface opposite to the front surface 56 f among the end portions 56 e of the resin layer 56.

  The end portion 56e of the resin layer 56 can also be expressed as connecting the resin layer 56 and the film base 12.

  In this manner, the IML molded product 50 is prevented from being exposed to the outside because the boundary surface between the metal layer 13 and the film substrate 12 is covered with the end portion 56e of the resin layer 56.

  Further, the end portion 56 e of the resin layer 56 can be expressed as a region of the resin layer 56 where the film thickness is increased.

  In FIG. 6B, the end portion of the ink layer 14 is not bent, and the end surface of the ink layer 14 is covered with the surface 56f of the end portion 56e of the resin layer 56.

  Here, the IML molded product 10 shown in FIG. 1 is easier to mold than the IML molded product 40 shown in FIG. Further, in the IML molded product 50 shown in FIG. 6B, the end portion 56e of the resin layer 56 and the metal layer 13 are not closely adhered. For this reason, although peeling with the metal layer 13 and the film base material 12 in a warm water test can be reduced, the edge part 56e of the resin layer 56 and the metal layer 13 may peel in a warm water test.

  For this reason, like the IML molded product 10 shown in FIG. 1, the configuration in which the end portion 14 e of the ink layer 14 below the metal layer 13 covers the end surface 13 e of the metal layer 13 is easier to mold, Reliability in the adhesion test can be improved more reliably.

  The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope shown in the claims, and embodiments obtained by appropriately combining technical means disclosed in different embodiments. Is also included in the technical scope of the present invention.
