Lost Cores for High-Pressure Die Casting

Development of salt cores prepared by high-pressure squeezing and shooting with inorganic binders has shown a high potential of the given technology even for high-pressure casting of castings. Strength, surface quality of achieved cas tings, and solubility in water become a decisive criterion. The shape and quality of grai n surface particularly of NaCl ‐ cooking salts that can be well applied without anticaking additives has shown to be an important criterion. T hus the salt cores technology can cover increasingl y growing demands for casting complexity especially for the automobile industry.
