That’s a common and traditional process used for making lapel pins. After polishing and plating processes, adding the selected enamel Pantone colors to the appropriate areas of the pin, the pin is then baked in a hot oven to form a firm surface. An epoxy coating can be added if desired to prevent color fading for soft enamel pin. >>watch production video>>
The pin sets a little lower than the raised metal lines of the design giving the pin a 3D look. This is also the biggest difference with hard enamel in appearance.
For the pin design, the smallest minimum color area 0.3mm and the raised metal line thickness should be 0.2mm. For some designs that need to be cut, the cut area needs to be at least 2mm.
