WebA simple example of conventional impression die forging is illustrated in Figure 5-11. As the two dies approach, the workpiece undergoes plastic deformation, flowing laterally until it touches the side walls of the impression. A small amount of metal continues to flow outside of the impression, forming flash. As the dies continue to approach, the flash is thinned … WebWhat is flash forging? In the forging process, when the upper die applies the pressure on the hot object inside the bottom die, excess metal squirts out of the cavity as a thin … WebA flash can act as a cushion for impact blows form the finishing impression and also help to restrict the outward flow of metal, thus helping in filling of thin ribs and bosses in the upper die. The amount of flash depends on the forging size and may vary from 10 to 50 per cent. The flash flows around the forging in the parting plane. bcg medac set
