SOFT ENAMEL is the most common way for custom metal pins. The recessed part of the badge can be filled in colors, and the raised part of the badge can be used for various electroplating effects. The surface can be coated with a layer of transparent protective resin (Epoxy). This process is commonly known as “dome” (note that because of light refraction, the surface of the badge will be bright after the epoxy is applied), but the soft enamel badge after adding epoxy the unevenness is lost, but it can protect the logo.  The color for soft enamel is bright, the lines are clear and lively, and the metal material has a strong texture. You can use brass or iron as the raw material. The iron stamped soft enamel badge is cheap and good. If you have a small budget, you can’t miss it!
