... reheated to achieve the structures necessary for casting. The second casting process combines billet sawing, reheating, and the actual injecting of material into the mold. The article focuses on these processes and provides information on rheological tests. It discusses some key design concepts used in...

... stock and sawing slugs from it. With complex or large shapes, an impression called a “fuller” is used to reduce the cross section and to lengthen the forging stock. The fuller is usually elliptical in the longitudinal section. A “blocker” serves to prepare the shape of the stock before it is forged to...
