Abstract: A segmental crimper comprises at least three crimper segments and an actuator. The crimper segments are arranged circumferentially about a crimper axis that defines axial and radial directions. The crimper segments are movable relative to each other in a manner such that the crimper segments collectively define a variable size aperture that is aligned with the crimper axis. Each of the crimper segments comprises a radio frequency heating element. The actuator is operatively connected to the crimper segments in a manner such that movement of the actuator causes all of the crimper segments to simultaneously move relative to each other and alters the size of the aperture.

Abstract: A method comprises resiliently deforming the object via a mold that comprises first and second mold members that are movable between open and closed positions. The first and second mold members define a parting line or gap and a mold cavity when closed. The mold cavity is shaped such that the thermoplastic object is resiliently deformed in the mold cavity when the first and second mold members are closed. Thereafter, a portion of the mold is heated in a manner such that the object partially melts while the parting line or gap of the mold remains below the melting temperature of the object (thereby eliminating flashing). The object is then allowed to cool in the mold with the first and second mold members closed such that the object at least partially takes the shape of the mold cavity when the object is in equilibrium and is released from the mold cavity.
