Coining is used in the finishing stages of the manufacturing process. It adds very fine details to the surface of a piece of metal. Because of the intricacy involved, it is performed in the cold. There is also no lubrication required because it is possible that this could hinder the design if the punch slipped.
There is tremendous pressure needed, but an advantage of this is you don’t require expensive CNS machines to reach the desired tonnage. If you need something coined, the metal fabricators at Frontier Metal Stamping have the tools and experience to create exactly what you require. Contact us or come by the shop today.
