Patent ID: 8907820

Claim:
A method for manufacturing a metal keyboard for a computer, comprising the steps of manufacturing a keyboard component and then assembling the keyboard component; wherein the keyboard component contains an aluminum panel, a plurality of keys, a plurality of key brackets, a metal key tray, a circuit board, an enhancement and weight increasing steel plate and a base plate; and wherein the keys are constructed by injection molding or stamping process; the key brackets are formed by injection molding twice and then connecting with each other; the aluminum panel is formed by the steps of: performing a stamping process to the sheet of thin aluminum which is used for making the panel; performing nano-molding process T to the aluminum panel after the stamping process so as to define a plurality of nano-micro-pores on the panel; processing the aluminum panel after the nano-molding such that a plastic body is formed on and secured onto the panel by injection molding, one side of the plastic body being combined with the nano-micro-pores and secured onto the underside of the aluminum panel, while the other side being provided with a plurality of plastic pins which are formed by injection molding and projected from the surface of the plastic body; the metal key tray is formed by a stamping process, a number of micro-pores are defined by stamping process in the metal key tray at locations corresponding to the plastic pins; making the plastic pins distributed on the plastic body received into the corresponding micro-pores of the metal key tray; hardening the plastic pins by hot melting after they are received into the corresponding micro-pores of the metal key tray such that the pins are locked onto the metal key tray, thus forming the aluminum panel and metal key tray; the base plate is formed by injection molding process; the key and corresponding key bracket are connected and assembled with each other mechanically; the key bracket, aluminum panel, and metal key tray are connected and assembled with each other mechanically; the aluminum panel, metal key tray, and circuit board are connected with each other by means of double-sided tape; and the enhancement and weight increasing steel plate is secured onto the base plate using double-sided tape.
