Description

Technical Field

[0001] The utility model relates to the technical field of automotive parts, specifically to a panel. Background Art

[0002] The INS process is mainly used in parts such as door panel decorative strips, center consoles, and instrument panels in vehicle interiors. The INS process is to pre-form the film sheet into the shape of the outer surface of the product through high-pressure adsorption in a forming mold, and after trimming the edges, place it into the injection mold of the product, and then injection mold it together with the molten plastic.

[0003] The conventional structure of the INS film sheet is composed of three layers: a PMMA (acrylic) layer, an ink printing layer, and an ABS substrate layer.

[0004] Chinese Patent with Publication No. CN114147913A discloses an interior and exterior automotive part with a two-color injection-molded intermediate INS film sheet, including an outer transparent plastic plate, an INS film sheet, an inner transparent plastic plate, and a painted light-shielding layer arranged in sequence from top to bottom. This device has the following defects:

[0005] 1) An inner transparent plastic plate is sandwiched between the INS film sheet and the painted light-shielding layer. Since the INS film sheet already has a plastic substrate layer at the bottom, the addition of the inner transparent plastic plate will increase the thickness of the product and also lead to an increase in cost.

[0006] 2) The use of a painted light-shielding layer requires a painting process, which increases the processing steps, is complex in process, and wastes cost.

[0007] 3) The surface of the outer transparent plastic plate is smooth and cannot achieve the visual effect of optical refraction. Summary of the Utility Model
