Abstract

The present invention relates to an elastic rubber key product and its production method. A keyboard composed of elastic rubber and plastic film includes a keyboard body composed of elastic rubber, a skin composed of plastic film, and an adhesive layer between the two. The bottom of the keyboard body is fitted with connection element to contact and connect to an external circuit. The back of the plastic film is printed with icons required by the keys. The adhesive layer is coated on the back of the plastic film. The plastic film printed with icons is firstly cut to pieces having the same size as the key surface by a cutting mold, by cutting manually or by compression molding. The cut-out plastic film piece is then put into a cavity of a female mold. Next, uncured elastic green rubber cut into proper size is put into the male and female mold to be heated and cured following the conventional compression molding procedure. Since the surface covering layer of every single key is a plastic film piece printed with an icon, which is pre-cut and put into a female mold cavity individually, keyboards with different key arrangement are molded simply by putting plastic film pieces printed with different icons into the key mold cavity, wherein the plastic film piece can be made in the form of little pieces of plastic film plate.
