ABSTRACT:
A one-piece keyboard housing in a simple but compact manner is provided by using an internal gas pressure injection molding process (air mold process). With this process, the keyboard housing can be formed as a one-piece molded part with recesses and cavities. The cavity serves to reduce weight, and the process itself improves stability within the keyboard housing. The molded part is formed of a traylike first housing shell, in which a keypad can be mounted, and a second housing shell with recesses that joins the first housing shell in an n-shape.
