The manufacturing of 3D Cast lapel pins differs in many ways from Die Struck lapel pins. The biggest difference is in the way the pin is formed. 3D Cast lapel pins use a rubber mold that accepts molten metal. The use of a rubber mold and molten metal allows for the 3D Cast lapel pin to have more dimension and details. The mold is spun at a high revolution rate as molten metal is added to a port on the mold.
