Abstract
A method for encapsulating at least a portion of a heat sink insert with plastic material has been provided in which flashing has been eliminated. There is provided a heat sink insert which has a bottom surface, a shoulder portion, and a rib member formed integrally with and extending upwardly from the shoulder portion to define a crush zone. The rib member is deformed to conform with the contour of a cavity formed by the first and second mold plates so as to create a seal between the insert and the cavity. The rib member also serves to compensate for dimensional variations of the insert and the cavity.
