Die casting of component having integral seal

摘要

A method of die casting a component (29) having an integral seal (33) includes defining a first portion (80) of a die cavity (158) of a die (150) to include an open cell structure (85). A second portion (82) of the die (150) is defined without the open cell structure (85). Molten metal (M) is injected into the die cavity (158), and the molten metal (M) is solidified within the die cavity (158) to form the component (29) having the integral seal (33).
