[0030] Please refer to Figures 1 to 4 , the present invention provides a forming process for a luggage case shell with a scattered dot visual effect, which is used to process the luggage case shell 100. The luggage case shell 100 has a scattered dot visual effect with dense distribution and irregular arrangement visually. The forming process for the luggage case shell with a scattered dot visual effect includes the following steps:

[0031] (1) Production of the scattered dot plate 10: Provide a substrate 11 and coat high-temperature resistant coatings 12 on both the front and back of the substrate 11. Among them, the material of the substrate 11 is transparent PET (Polyethylene Terephthalate) material. The high-temperature resistant coating 12 is a silica coating. In subsequent high-temperature treatment processes, the high-temperature resistant coating 12 can protect the substrate 11 to prevent deformation and damage of the substrate. Among them, the thickness of the substrate is 1 - 4 mm, and the thickness of the high-temperature resistant coating is 0.2 - 1.2 mm.

[0032] (2) Production of the scattered dot particles: Break the scattered dot plate 10 on a crusher to form scattered dot particles. The size of the scattered dot particles is 0.1 - 1.5 mm. Each scattered dot particle includes a miniature substrate 11 and miniature high-temperature resistant coatings 12 attached to both sides of the substrate 11.

[0033] (3) Preparation for the production of the surface layer 20, the color layer 30, and the variegated layer 40:

[0034] When preparing for the production of the surface layer 20, heat the transparent PC (Polycarbonate) to a molten state, and then uniformly mix the scattered dot particles on the molten PC to form a mixture of PC and scattered dot particles.

[0035] When preparing for the production of the color layer 30, heat the PC and the color masterbatch to a molten state and mix them evenly. The color masterbatch adds the designed color of the product to the color layer 30.

[0036] When preparing for the production of the variegated layer 40, heat the recycled waste luggage case shells or the scraps of the luggage case shells to a molten state.

[0037] (4) Extrusion molding: On an extruder, the surface layer 20, color layer 30, and variegated layer 40 obtained in step (3) are co-extruded in three layers. After cold cutting, a planar luggage board is obtained, wherein the color layer 30 is sandwiched between the surface layer 20 and the variegated layer 40.

[0038] (5) Molding of the luggage shell 100: The luggage board obtained in step (4) is softened in an oven and then blow-molded on an aluminum mold to form the luggage shell 100.

[0039] It can be understood that in this embodiment, the surface layer 20, color layer 30, and variegated layer 40 are simultaneously provided, and the surface layer 20, color layer 30, and variegated layer 40 are formed by co-extrusion molding. In other embodiments, the variegated layer 40 may not be provided, and the surface layer 20 and color layer 30 are directly extruded and molded on an extruder, and the surface layer 20 covers the outer surface on one side of the color layer 30.

[0040] The beneficial effect of the luggage shell molding process with a scattered dot visual effect of the present invention is that by making the scattered dot board 10 and breaking the scattered dot board 10 to form scattered dot particles, the scattered dot particles are mixed on the transparent luggage surface layer 20. After the production of the luggage shell 100 is completed, a unique scattered dot visual effect is formed on the luggage surface, effectively improving the attractiveness of the product and increasing the selling points of the merchant.

[0041] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0042] The above-described embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent should be subject to the appended claims.
