Embodiment
Below in conjunction with accompanying drawing the injection article with metal-like provided by the invention is elaborated.Fig. 7 is the polyhedron metallics structural perspective of the injection article with metal-like provided by the invention." A " position transversary sectional view among Fig. 5 when Fig. 8 carries out injection moulding for utilizing the plastic material that contains the polyhedron metallics among Fig. 7.As Fig. 7, shown in Figure 8, the injection article with metal-like provided by the invention is to utilize the method manufacturing identical with prior art to form, and just is blended in metallics 198 in the molten plastic material thing and has shown in Figure 7 polyhedron-shaped.This metallics 198 is the polyhedral structures that passed through the about 30 μ m of mean diameter that pulverize and form by aluminium-magnesium alloy materials, and make by the material that vacuum evaporating method covering last layer has metal-like on the surface.Because the intensity of aluminium-magnesium alloy is high, therefore can make the particle that is polyhedron-shaped at an easy rate, and owing to contain aluminium, thereby it is very outstanding to show the reflectivity of metal-like by the method for pulverizing.In addition, in order to obtain excellent more metal-like, can carry out plated film to polyhedron-shaped metallics 198 surfaces by the method for vacuum evaporating provides its reflectivity.Wherein the mixture ratio of aluminium and magnesium is 3: 7～7: 3.When the ratio of aluminium surpasses 70%, the snappiness of aluminum-magnesium alloy particle will increase, thereby be difficult for pulverizing, and if the ratio of aluminium is lower than 30%, then significantly decline of reflectivity.In addition, though the reflectivity of aluminum is higher, because its snappiness height, so be difficult to have polyhedron-shaped structure by the method formation of pulverizing.And after the aluminium-magnesium alloy that will be easy to pulverize is ground into the polyhedron that mean diameter is 5 μ m～120 μ m, by the method for vacuum evaporating plated film is carried out on its surface then, and it is blended in the molten plastic material thing of injection moulding and when making injection article, upper and lower part framework 10, the A place, position that resin flow 99 crosses mutually in 20 also can fully guarantee its reflectivity, therefore can make the whole surface of injection article embody even metal texture.Wherein the mean diameter of polyhedron aluminum-magnesium alloy particle is advisable with 10 μ m～40 μ m, and this is because of polyhedral mean diameter not simultaneously, its reflectivity difference, and viewed color also can be different.That is, polyhedral mean diameter is more little, and the color that it presented is bright more; Otherwise polyhedral mean diameter is big more, and the color that it presented is dark more.But if polyhedral mean diameter exceeds 120 μ m, its reflectivity can descend greatly, therefore should remain on below the 120 μ m.In addition, can present silver color when polyhedral mean diameter is 10 μ m～40 μ m, this point is best for embodying metal-like.In addition, before vacuum evaporating is carried out on the polyhedron surface of being made by the magnesium-aluminum alloy material, can also have the pigment of certain color, thereby can embody multiple different texture at its surface coated last layer.
When having polyhedron-shaped metallics 198 and be blended in the molten plastic material thing and and be injected into upper and lower mould frame 10 by inlet shown in Figure 4 50 with above-mentioned, in the time of in 20, the resin flow 99 that is formed by this melts will flow to the position A that crosses mutually along 2 different directions, and metallics 198 is arranged in shape shown in Figure 8 at this position.As mentioned above, the tabular aluminium foil 98 of prior art at the A place, position of formation welding line 90 shown in Figure 6 in vertical state, thereby cause reflectivity sharply to descend.But as shown in Figure 8, vertically be arranged in A place, position even have the metallics 198 of polyhedral structure among the present invention, because its arbitrary face all has uniform reflectivity, thereby its metal-like that embodies is identical with other position.The injection article of making by aforesaid method with metal-like, because a plurality of polyhedron metallicss 198 of the about 30 μ m of mean diameter are contained in its inside, thus can on its whole surface, present silver color, and can embody even metal texture.
