Title:
METHOD FOR MANUFACTURING LIGHT EMITTING KNOB
Document Type and Number:
WIPO Patent Application WO/2016/114499
Kind Code:
A1
Abstract:
The present invention relates to a method for manufacturing a light emitting knob, which has a new process introduced to prevent a character having been separated from a light blocking metal plate from escaping from a resin layer in a display window forming step and a surface treatment step regardless of the shape and kind of the character which forms a light emitting display window, thereby significantly lowering a defect rate. The method comprises: a metal plate processing step for processing a light blocking metal plate to have a shape having a closed upper portion and an open lower portion; a display groove forming step for forming a light emitting display groove to be recessed at the upper inner surface of the light blocking metal plate; a resin layer coupling step for insert-molding and coupling a resin layer of a light transmissive synthetic resin to be coupled to the light emitting display groove at the lower inner side of the light blocking metal plate, using the light blocking metal plate as an insert; and a display window forming step for horizontally cutting the top surface of the light blocking metal plate and exposing the top surface of the resin layer coupled to the light emitting display groove, thereby forming a light emitting display window.
