  • Publication number: 20110223352
    Abstract: A method of making a keycap structure including steps of colored plastic body formation, final coating spraying, baking, laser engraving, transparent layer covering, and finishing. Through the aforesaid steps, at least a colored plastic body is pre-formed. The colored plastic body has a to-be-processed surface. The to-be-processed surface is spray-coated with a final coating. The colored plastic body and the final coating are baked to allow the final coating to harden on the to-be-processed surface. The final coating is processed by a laser beam to format least a hollowed portion. The hollowed portion of the final coating and the correspondingly exposed to-be-processed surface together constitute at least a pattern portion. The pattern portion and the final coating are covered with a transparent layer to protect the pattern portion and the final coating, and a keycap structure is finished from the colored plastic body.
