ABSTRACT:
A process for making a valve housing for a prosthetic socket. The process eliminates the need for a male and female mold by applying an elastic resilient separator material over the entire surface area of a housing mold, sealing one end of the material to enclose the surface area of the housing mold, applying a vacuum to the sealed material so that the material closely conforms to the entire surface area, applying an outer elastic resilient separator material to the housing mold over the reinforcing materials so as to trap the reinforcing materials to control thickness and shape, applying a vacuum thereto to force the outer elastic resilient separator and underlying reinforcement material to closely conform to the housing mold; and adding the resin molding material to impregnate the reinforcing materials.
