What is Insert Molding?

Insert molding (often called double shot or two-shot molding) is the process of shaping plastic around preformed metal or plastic inserts. Insert molding keycaps is a two-stage process. In the first stage, the legend (word, number, graphic, etc.) is molded onto a plastic carrier. This plastic carrier insert, referred to as the first shot, is then placed in a second mold. Plastic is then injected around the first shot forming the keycap shape but leaving the top of the legend exposed. The second shot process also forms the keycap’s mounting detail. If legend wear is a concern, double shot keycaps offer the greatest durability.
