Beschreibung
Zusammenfassung:	A mandrel configured to facilitate release of an elastomeric part cured thereon may comprise an elongated body having an outer surface, an internal cavity formed in the elongated body, and a passage providing fluid communication between the internal cavity and the outer surface of the body. The passage may be dimensioned so as to permit a flow of a fluid from the internal cavity to the outer surface of the body and to preclude a flow of an uncured elastomer into the passage. The flow of the fluid from the internal cavity to the outer surface may cause the fluid to intervene between the outer surface of the mandrel and the elastomeric part to facilitate the release of the elastomeric part from the mandrel.
