Metal thin sheet sintering plastic outer parts and its manufacture method

Abstract

The invention relates to an external part of metal with plastics and a forming method of electroforming thin plate embedded injection which is particularly suitable for manufacturing various external components of mobile handset, laptop computer, press key pads, etc. The external components have functions and features of special metal surface and plastic internal parts and are suitable for mass production. The processes include the manufacture of laser fabrication, drilling, cutting, surface finish, hairline, electric discharge and etching on the electroform mold before casting the thin plates and manufacturing the thin plates into semi-finished external products; then applying adhesives on the back of the semi-finished external products which are solidified in the plastic molds and processing injection in order to allow the final finished external products to achieve the combination structure of metal plates attached with injected plastic parts.

Description

technical field [0001] The present invention relates to an appearance part of metal flake fusion-bonded plastic, and a manufacturing method of metal electroforming combined with plastic injection molding for manufacturing the appearance part, in particular to a method of combining a finished product with a special metal surface and a plastic inner part Products with functions and characteristics and their electroformed sheets are embedded in injection molding. Background technique [0002] At present, the common exterior parts on the market, such as mobile phones, notebook computer casings, buttons, etc., are metal (aluminum alloy) exterior parts made by electroforming. Because the metal itself is hard and durable, it can be used in Its surface is processed in various ways, and it can present a special processing surface, such as mirror surface, hairline, etc., but relatively limited by its hard material, it is impossible to make more complex functional structures, such as b...

[0002] At present, the common exterior parts on the market, such as mobile phones, notebook computer casings, buttons, etc., are metal (aluminum alloy) exterior parts made by electroforming. Because the metal itself is hard and durable, it can be used in Its surface is processed in various ways, and it can present a special processing surface, such as mirror surface, hairline, etc., but relatively limited by its hard material, it is impossible to make more complex functional structures, such as bonding, locking, Positioning structure, etc., if it is directly manufactured by machining, it will not only consume time and effort, but also increase the cost and not meet the economic benefits
