Manufacturing method of metal high temperature gas assisted moulded and combined plastic

Abstract

The invention discloses a manufacturing method of a metal high temperature gas assisted moulded and combined plastic. According to the manufacturing method, a metal sheet is placed in a mould, a pressure is applied on the metal sheet, the mould is heated by a heating device so as to soften and deform the metal sheet, then the softened metal sheet is blown into a mould cavity by high pressure gas,after the metal sheet is moulded, the metal sheet is taken out, a high temperature gas assisted moulded metal element is obtained, and then the metal element is combined with a plastic element.

Description

technical field [0001] The production method of metal high-temperature gas-assisted molding combined with plastic of the present invention is mainly applied to mobile phones, tablet computers, notebook computers, glasses, cosmetic boxes, car decorations and lighting decorations, etc., and has high-temperature gas-assisted molding of metal and plastic components. In terms of molding technology combined with plastic. Background technique [0002] Press, the mobile phone needs to rely on the antenna to receive and transmit signals. There are two ways to install the antenna on the mobile phone. One is the traditional old external antenna, and the other is the current common built-in antenna. The external antenna protrudes from the mobile phone case. Outside the body, in addition to being less aesthetically pleasing, the external antenna protruding from the outside of the mobile phone casing is easily bent or broken due to collisions. So the current common mobile phones use buil...

Problems solved by technology

[0007] The metal components mentioned above are generally formed by extrusion or stamping. The appearance of the metal components still needs to be reused after drawing or sandblasting or polishing or grinding. Textures or reliefs or totems, after many complicated processing procedures, the appearance of metal components can show a mirror effect with different roughness or different textures or different relief totems, which is not only labor-intensive and time-consuming, but also high in production costs. After a period of time, the tool will wear and tear, resulting in an increase in the tolerance of the machining accuracy, resulting in the production of defective products, because of the existing problems and deficiencies that have yet to be overcome.
