US 2001/0040305 A1 · PLANT FOR PRODUCING PRESSURE DIE-CAST OR INJECTION MOULDED ARTICLES USING SALT CORES

Abstract

Plant for producing pressure die-cast or injection moulded articles having a unit for producing salt grains, a press for forming salt filler cores by compressing the said salt grains, a pressure die-casting machine for making the said articles by injecting a material in the liquid state into a mould having at least one salt filler core, and a salt removal and washing unit designed to remove the salt filler cores that have been trapped within the said articles; the said unit for producing salt grains being designed to atomize a saline solution which is supersaturated with salt into a plurality of drops so as subsequently to cause the salt present in solution/suspension in each drop of solution to solidify into a corresponding salt grain.
