Abstract: A die for reducing the formation of flash on parts includes a first die section and a second die section defining therein a cavity. The first die section includes a pair of first surfaces and the second die section includes a pair of second surfaces which together define a pair of parting lines which extend from opposite sides of the cavity. Desirably, the first die section includes a pair of lands, each extending along the length of one of the parting lines. Each land defines a first surface portion of the first surface and is sized and configured so that the land is elastically loaded, e.g., substantially equal to and less than the elastic limit of the material forming land when forming a part.
