Abstract
A method of making a spring-energized elastomeric seal is disclosed in which the seal has a C-shape or a U-shape spring substantially surrounded by an elastomer. The method uses a male die section upon which the spring is loaded. A female die section is positioned around the male section. Elastomer is injected, cooled and the die sections pulled apart yielding the finished seal.
