WebA variation of closed die forging is called flashless forging or true closed die forging. In this type of forging the die cavities are completely closed which keeps the workpiece from forming flash. The advantage to this process is that less material is lost to flash. Flash can account from 20 up to 45% of the starting material. WebClosed-die forging without flash is also known as no flash die forging.
