Silica-gel push-button and forming method thereof

Abstract

The invention discloses a silica gel keystroke and a formation method thereof. The silica gel keystroke comprises a keystroke basal body and keystroke characters arranged on the surface of the keystroke basal body. The keystroke characters and the keystroke basal body are all made of silica gel and are molded to be integral through heat pressing. The formation method includes the following steps: a), processing a keystroke die which has a first die cavity and at least one second die cavity arranged at the bottom of the first die cavity; b) infusing the liquid silica gel into the second die cavity; c), putting solid silica gel into the first die cavity; and d), combining the liquid silica gel and the solid silica gel through heat pressing. In this way, a silica gel keystroke can be made. By combining the liquid silica gel and the solid silica gel through heat pressing to make the silica gel keystroke, the invention is high in processing efficiency and simple in process. The silica gel keystroke is wear-resistant and reduces the costs on manpower and material resources and ensures the quality of the silica gel keystroke. Molded from liquid silica gel through heat pressing, the keystroke characters on the silica gel keystroke are more wear-resistant.
