Finished product with surface decoration, forming machine thereof and manufacturing method thereof

Abstract

The invention relates to a finished product with surface decoration, a forming machine thereof and a manufacturing method thereof. The forming machine comprises a machine body, an upper die base, a lower die base, an infrared heating device, a vacuum air exhausting device and a low-pressure hot gas supply device, wherein the lower die base comprises a movable part and a fixed part inserted into the movable part, the movable part is used for arranging a thin film, and the fixed part is provided with a fixture used for carrying a workpiece; the infrared heating device can be moved to the middle of the upper die base and the low die base and heats the thin film; the vacuum air exhausting device is connected to the lower die base to pump air below the thin film to form negative pressure; and the low-pressure hot gas supply device is connected to the upper die base to supply low-pressure hot gas to the upper side of the thin film to form positive pressure. Therefore, the forming machine carries out surface decoration on the surface of the workpiece, can reduce manufacturing cost and improves manufacturing yield.

Description

technical field [0001] The present invention relates to a surface decoration technology, in particular to a finished product with surface decoration made by implementing surface decoration technology on a finished workpiece, its molding machine and its manufacturing method, wherein the workpiece can be a plastic part or metal pieces. Background technique [0002] A known method for manufacturing a finished product with surface decoration uses an in-mold decoration (In Mold Decoration, IMD) technique to place a decorative image on a workpiece made by injection molding. It can be printed. The image is printed on a film body to form a film with a decorative image, and then the film is combined with the workpiece by injection molding to complete a finished product with surface decoration. [0003] The advantage of in-mold decoration technology is that it can form a multi-colored and textured three-dimensional structure object, making the appearance of the workpiece present the ...

AI Technical Summary

Problems solved by technology

[0005] 1. The film must first be formed into the required three-dimensional shape, then punched by a punching knife die, and finally placed in the injection mold for the injection process of the plastic material, so that the film is combined with the injection-molded workpiece, and the forming process Complicated, low manufacturing yield and high manufacturing cost

[0006] 2. It cannot be applied to metal workpieces made of non-injection molding (such as aluminum, magnesium and other metal materials)

[0007] 3. Since the film is prone to cracks or wrinkles at the bends and corners, and the molding depth is limited by its material characteristics, it is easy to cause poor decorative images. Therefore, the shape design of the workpiece applied to the in-mold decoration technology There must be many conditions on the surface, which greatly restricts the shape of the workpiece
