Stamping Die Parts, Also known as metal press tools, are components used in metal stamping dies. Stamping die components are also known as press die components, tool and die components, or progressive die components. Stamping dies are not the same as die-casting or plastic injection moulds. They are most similar to the cold-forming cutting method for relatively thin metal components, often known as sheet metal parts. Thin metal components can be quite big for the automotive sector or extremely microscopic for the microelectronics and semiconductor industries.
