Patent ID: 8557168

Claim:
A method for molding an external breast prosthesis comprising: providing a die mold having a concaved cavity; positioning a die cover on the die mold to enclose the concaved cavity to form a thin cup-shaped die cavity; injecting an elastomeric material into the die cavity; curing the elastomeric material in the die cavity to form a thin-walled anterior shell; removing the die cover from the die mold; forming a chamfered perimeter edge on the anterior shell; spreading an elastomeric material on a surface of a die plate, wherein the elastomeric material has a viscosity which allows the elastomeric material to remain on the surface of the die plate and form a thin-walled posterior shell; locating the die mold in an inverted position on top of the surface of the die plate such that the die mold supports the anterior shell over the posterior shell; curing the elastomeric material on the die plate such that the anterior shell bonds with the posterior shell at the chamfered perimeter edge to form an external breast prosthesis having an air-filled interior cavity, wherein the chamfered perimeter edge forms a mitered joint between the anterior shell and the posterior shell; removing the die mold from the die plate: and removing the breast prosthesis from the mold cavity.
