ABSTRACT:
In accordance with the teachings of the present invention, a mold comprises a nubbin positioned within the mold, and an actuator positioned within the mold to align the nubbin. The actuator may be implemented with a piezoelectric material, a magnetorestrictive material, an electrorestrictive material, etc. In one embodiment, the actuator is formed into a cylinder and placed around a nubbin in a mold. When the actuator receives a stimulus, the actuator constricts decreasing the size of the inner diameter. Decreasing the size of the inner diameter causes the actuator to constrict and align the nubbin along a centerline.
