The manufacturing process "photo etch" is usually used for very thin products with thickness less than 0.8mm. And another advantageis that the metal lines of photo etched pins can be much thinner than die struck pins and die casted pinsAn image of your design is transferred from a photographic negative onto the surface of the metal. Your design is then etched into the

brass or steel using an acid-reaction process.Al the acids and other impurities are carefully rinsed of. The indentations are then filed with the enamel colors. Colors are inserted byhand. one at a time. using different sized svringes, The sheet of metal is then fired at 450 for 12 to 15 minutes pins are then cut out

of the sheet accordina to vour custom desian.Non-colored (raised) sections of the pin are then plated to a shiny gold finish. An optiona epoxy protective coating (dome) can thenbe applied to protect the color enamels from fading or cracking over time.
