Abstract
One aspect is an insert molded friction torque device with a rotatable shaft, a friction element mounted over the rotatable shaft in an interference fit, a rigid enclosure structure at least partially enclosing the friction elements, and a single-piece molded housing enclosing the friction element and at least partially enclosing the rigid enclosure structure such that a first portion of the housing is between the friction elements and the rigid enclosure structure within the rigid enclosure structure and a second portion of the housing is outside the rigid enclosure structure.
