Abstract

The invention discloses a film-covered profile and a preparation method thereof and relates to the field of surface decoration materials of plastic parts. The film-covered profile comprises a plastic machine body and a PET thin film adhered on the back surface of the plastic machine body. The preparation method comprises the following steps of: (1) selecting a flexible PET thin film with decorative textures; (2) cutting the PET thin film into thin-film strips conforming to the needed width; (3) putting the PET thin-film strips into a forming cavity of an extruding mold, then fusing with hot-melt plastic extruded by an extruding machine in the forming cavity of the mold and extruding the film-covered profile with decorative effect. The film-covered profile and the preparation method disclosed by the invention have the advantages that the length of the extruded profile is not limited, and the process steps of preprocessing forming and coating adhesive agents are omitted; the existing production process of carrying out surface treatment after the whole injection molding can be replaced, and the problem that the surface effect is bad after the plastic is extruded and formed can be solved; and the PET thin films with different colors and textures can also be quickly replaced, and the customization demand for diversified and personalized textures can be quickly realized.

Description

technical field [0001] The invention relates to the field of surface decoration materials for plastic parts, in particular to a film-coated profile and a manufacturing method thereof. Background technique [0002] The manufacturing method of composite decorative plastic parts in the prior art is to first coat a layer of adhesive on a metal sheet, then use a bending machine to turn over and shape it, and finally fuse it with hot-melt plastic, and extrude a film-coated profile through an extrusion die. This method requires metal sheets to be preformed and of limited length, and the adhesive adhesion strength is not stable. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a film-coated profile with fast production speed and high yield, which is especially suitable for substantially unlimited length and can be completed in an extrusion die, and its manufacturing method. [000...
