Embodiment Construction
[0016] Such as figure 1 As shown, the present invention provides a molding method of a composite product.
[0017] A preferred embodiment of the molding method of the composite material product of the present invention is to attach the attached film to the surface of the composite material using in-mold decoration molding technology, which mainly includes the following steps:
[0018] Step 102, providing an attached film.
[0019] Step 104, attaching the attached film to the mold cavity of the master mold of an in-mold decoration molding mold.
[0020] Step 106, closing the mold, and injecting molten composite material into the mold cavity. The composite material consists of a base plastic and additional materials. The basic plastics include polycarbonate (PC), polycarbonate and acrylonitrile-butadiene-styrene copolymer mixture (PC / ABS), polyhexamethylene adipate (PA66), acrylonitrile-butadiene - One or more materials in styrene copolymer (ABS). Additional materials inclu...

Abstract
The invention discloses a composite material product comprising a composite material layer formed by injecting a molten composite material. An attached thin film is attached on the surface of the composite material layer. The forming method of the composite material product comprises the following steps: providing the attached thin film; attaching the attached thin film in the mold cavity of the female die of an in-mold decoration forming mould; spotting a die; injecting the molten composite material in the mold cavity; maintaining the pressure and cooling; and opening the die so as to push out the composite material product which is characterized in that the surface of the composite material layer is attached with the attached thin film. In the composite material product and the preparation method thereof, the attached thin film is attached on the composite material, thus forming the beautiful composite material product.
Description
technical field [0001] The invention relates to a composite material product and a forming method thereof. Background technique [0002] When consumer electronic products are developing in the direction of light and small, in order to reduce the thickness of the product without weakening its strength, the traditional product material is developed from plastic to the addition of fiber (glass fiber or carbon fiber) on the basis of plastic. of composite materials. [0003] However, fibers will float on the surface of the composite material after injection molding, which affects the smoothness and aesthetics of the product surface. It often needs to be repaired and polished to meet the aesthetic requirements of the product. Contents of the invention [0004] In view of this, there is a need to provide an aesthetically pleasing composite article. [0005] At the same time, it is necessary to provide an aesthetically pleasing molding method for composite material products. ...
