Abstract: A metal part is hot formed by placing a metal part blank on a forming tool and installing a fabric cover over the forming tool, overlying the metal part blank. The fabric is at least partially wrapped around the metal part blank. The metal part blank is heated to a temperature sufficient to allow forming of the metal part blank. Forming pressure is applied to the metal part blank that conforms the metal part blank to the forming tool by tensioning the fabric.

Abstract: The present invention relates to an index/seal pin indexed precisely in a resin transfer molding die to assure the desired resin-to-fiber ratio in the mold part, and, thereby, to produce reliably and consistently a part of minimum weight with adequate strength. The index/seal pin seals via replaceable O-rings on the threaded stem of the pin to prevent low viscosity resin from exiting a mold cavity and invading the threads, bolts, pins, or other elements of the internal mandrel. The pin also assures accurate positioning of a mandrel in the die cavity while it allows the entire inner mandrel to be enclosed and sealed within the mold cavity, simplifying the sealing system.

Abstract: The present invention relates to a seal pin indexed precisely in a resin transfer molding die to assure the desired resin-to-fiber ratio in the mold part, and, thereby, to produce reliably and consistently a part of minimum weight with adequate strength. The index/resin seal pin of the present invention for RTM mold dies is novel in that it provides the seal (via replaceable O-rings) on the threaded stem of the pin to prevent low viscosity resin from invading the threads, bolts pins, or other elements of the internal mandrel. The pin allows the entire inner mandrel to be enclosed and sealed within the mold cavity, simplifying the sealing system. The invention also relates to a method for using the seal pin in a resin transfer molding process.
