Casting Procedure, Particularly for an Engine Cylinder Head |
摘要 |
Cast parts having internal cavities or passages are produced by using a main core and one or more secondary cores. The secondary cores are associated with the main core by coating the secondary cores with a material which dissolves on contact with mold metal. The cores to be coated can also be formed by hollow inserts made of a heat resistant material, filled with sand polymerized resin.
