Die-Struck and Die-Cast

Other lapel pin options include die-struck pins and die-cast, both of which can be enamel products. Die-struck pins are made by using a machine to put a huge amount of pressure on a piece of metal, molding it without heating it very much. The pressure forces the metal into the correct shape for the design, and from there the piece can receive the enamel finish.

Die-casting involves melting down the metal and pouring it into a mold, letting it cool before applying enamel or other decorative touches.

For die-struck pieces, look for a crisp, clear definition of the design, and for higher density. Die-cast lapel pins should be clear of blisters, cracks, and flow marks.
