Composite-material bright face shell production and products

Abstract

A process for preparing the bright shell from a composition includes such steps as providing an unsolidified composition onto the surface layer of a metallic mould, solidifying the composition by vacuum moulding method, and machining.

Problems solved by technology

[0002] Generally speaking, the casings of notebook computers, mobile phones, mice, or personal digital assistants (PDAs) are made of plastic or metal materials (such as: aluminum alloy, magnesium alloy); wherein, the plastic casing is made by injection molding. In addition, for the sake of refinement, the so-called ultra-thin injection molding method has also been developed. However, this method involves quite sophisticated manufacturing process technology, which makes its production cost higher. In addition, the molding object is not strong enough, easy to break, And the need for surface painting is also one of the main disadvantages of the ultra-thin injection molding method

[0003] As for the metal casing mainly made of magnesium alloy or aluminum alloy, in addition to the complicated manufacturing process, it is also difficult for the metal casing to meet the requirements of light weight due to the considerable weight of the metal; in addition, in order to prevent the surface of the metal casing from Oxidation and in order to maintain the appearance of the shell surface, generally after the metal shell is made, it is necessary to form a protective layer or a desired pattern on the surface of the metal shell by means of surface coating and spray painting. However, this method is quite time-consuming and labor-intensive, and The surface of the prepared casing is flat and has no three-dimensional effect, which cannot meet the various requirements of modern consumers for product appearance.

[0004] In addition to the above two methods, in Taiwan Patent No. 529,326, another casing manufacturing method for notebook computers, mobile phones and PDAs is disclosed, which is manufactured by using the known composite material lamination molding method (Press Molding) Composite material casing to obtain a lightweight, non-deformable, impact-resistant composite material casing; however, the brightness of the surface of the casing obtained by this method is insufficient, and it is still necessary to additionally coat a transparent resin on the surface before it can be manufactured. to obtain a smooth glossy shell, so there are still complexities in the manufacturing process

In addition, the surface of the prepared shell lacks three-dimensional feeling, and the use of this method to manufacture the composite shell cannot avoid the generation of air bubbles or pinholes on the shell surface, so the prepared composite shell cannot be applied to products with high quality requirements
