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 dif...

Embodiment Construction

[0035] In order to make it easy for those skilled in the art to deeply understand the structure of the present invention and the functional benefits that can be achieved, specific embodiments are listed hereby, and detailed descriptions are as follows in conjunction with the drawings:

[0036] A manufacturing method of high-temperature gas-assisted forming metal components, which is to place a metal plate in a mold, and apply pressure to the metal plate, use a heating device to heat the mold to soften and deform the metal plate, and then input high pressure The gas blows the softened metal sheet into the mold cavity, takes it out after forming, and obtains a high-temperature gas-assisted forming metal component. Wherein, the pressure and temperature applied on the metal sheet are determined according to the material and thickness of the metal sheet, and the input high-pressure gas and the pressure range applied to the metal sheet can both be 50kg / cm 2 ~350kg / cm2 The temperatur...

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...
