Abstract
The present invention relates to a method for manufacturing a light emitting knob based on a novel process that is capable of preventing a letter that is separated from a light blocking metal plate at a display window forming step from being separated from a resin layer irrespective of the shape or the type of the letter, which constitutes a light emitting display window, thereby considerably reducing a defect rate, and in particular, to provide a method for manufacturing a light emitting metal knob that introduces a new process so as to realize a surface color through anodizing processing from letters separated from a light blocking metal plate.
Claims9
A method for manufacturing a light emitting metal knob comprising:
- a metal plate processing step of forming a light blocking metal plate in a cap shape including an upper plate portion and a side plate portion;
- a display groove forming step of forming a light emitting display groove in an upper surface of the upper plate portion of the light blocking metal plate;
- a first resin layer coupling step of coupling a first resin layer, which is made of a light transmitting synthetic resin, to the upper surface of the upper plate portion of the light blocking metal plate so as to fill the light emitting display groove;
- an upper surface plane-cutting step of cutting the upper surface of the upper plate portion of the light blocking metal plate such that the first resin layer filled in the light emitting display groove is remained;
- an anodizing step of applying an anodic oxidation treatment to the light blocking metal plate and then applying an organic dye to realize a color;
- a lower surface plane-cutting step of cutting a lower surface of the upper plate portion of the light blocking metal plate such that the first resin layer coupled into the light emitting display groove is exposed from the lower surface of the upper plate portion of the light blocking metal plate to form a light emitting display window;
- and
- a second resin layer coupling step of coupling a second resin layer, which is made of a light transmitting synthetic resin, to the lower surface of the upper plate portion of the light blocking metal plate.
