3D Cast Pins, also known as Die Cast Pins, offer multiple levels of relief, not normally attainable using standard die-striking methods. Instead of only one raised area and one recessed area (as in two dimensional - 2D lapel pin styles) this type of sculpting shows topographical contours in order to create the complex shapes and detail of animals, architectural replicas and human faces for these. Unlike die striking, where a preset logo is physically struck into a blank (smooth piece of metal), 3D die cast lapel pins are produced when molten metal is poured under high pressure into a pre-created mold of your design. Pouring under high-pressure results in a clean smooth surface and a uniformly accurate final result. The dies used to create Cast 3D pins take a bit longer to make than standard 2D dies because they are more complex and are handmade. Once the pins have been poured and hardened, it is time to add the plating.
