Foam reservoir

Foamed reservoir molding is also known as elastic reservoir molding. It has had limited use. This process creates a sandwich of plastic-impregnated, open-celled, flexible plastic foam between the face layers such as fibrous reinforcements. When this plastic composite is placed in a heated mold and squeezed, the foam is compressed, forcing the plastic and air outward and into the reinforcement. The elastic foam exerts sufficient pressure to force the plastic-impregnated reinforcement into contact with the mold surface and simultaneously removing entrapped air.
