Patent ID: 8708691

Claim:
A resin transfer molding apparatus, comprising: a first tooling die and a second tooling die each tooling die comprising a plurality of stacked metal sheets positioned in generally perpendicular position relative to a contoured surface of each tooling die, the plurality of stacked metal sheets configured substantially adjacent to each other and having air gaps between individual stacked metal sheets, the air gaps forming a plurality of cooling passageways for passing a cooling medium therethrough; first and second susceptors respectively mounted on the first tooling die and second tooling die, the first and second susceptors including the contoured surfaces in facing configuration and defining a mold cavity for molding a part; a temperature control system including induction coils inductively coupled with the first and second susceptors; a resin transfer system for delivering resin from a resin source to the mold cavity; and means for introducing said cooling medium into the cooling passageways.
