CASTING WITH REUSABLE PRECISION, MOTION-CONTROLLED, WITHDRAWABLE CORES

摘要

A method of manufacturing includes providing a casting assembly, providing a material having solid, transition, and liquid phases, heating the material to form the liquid phase, supplying the material to the casting assembly, cooling the material, monitoring the solidification of the material from the liquid phase through the transition phase, and moving one of the casting mold or the reusable core in a first direction relative to the other when a substantial portion of the reusable core contacts the transition phase. The casting assembly comprises a casting mold and a reusable core inserted within the casting mold.

1. A method of manufacturing includes:
providing a casting assembly comprising:
a casting mold; anda reusable core inserted within the casting mold; providing a material that has a solidus temperature and a liquidus temperature, wherein the material has a solid phase at a temperature less than or equal to the solidus temperature, a transition phase at a temperature between the solidus and liquidus temperatures, and a liquid phase at a temperature greater than or equal to the liquidus temperature; heating the material to form the liquid phase; supplying the material to the casting assembly; cooling the material; monitoring a solidification of the material from the liquid phase through the transition phase; and moving at least one of the casting mold and the reusable core in a first direction relative to the other when a substantial portion of the reusable core contacts the material in the transition phase.
