Two-material injection molding method.

摘要

The complete, two-colour, multiple keybutton array of a keyboard is molded by a two-shot injection molding method which uses a rotating, double female die (14, 18) selectively cooperating with two male dies (15, 19). The finished keybutton array is ejected to a carrier plate which then cooperates with a tray having movable keybutton compartments, which are then movably adjusted to place the keybuttons in position for automatic assembly to a keyboard.
