ABSTRACT:
A method and apparatus for forming runners (47, 56) in a mold assembly (10, 50). The mold assembly (10, 50) has a cavity plate (11, 51) and a sealing plate (12, 52). The sealing plate (12, 52) has a sealing plate cavity (18) in which a resilient material (14) is placed. A floating seal (13) is movably mounted to the sealing plate (12) such that the floating seal (13) is on the resilient material (14). A workpiece (19) is placed on the resilient material (14) and the cavity plate (11, 51) is mated with the floating seal (13) thereby forming the runners (47, 56). The resilient material (14) imparts a force on the floating seal (13) and pushes the floating seal (13) against the cavity plate (11, 51) to prevent leakage of encapsulating material from the runners (47, 56).
