Abstract
A plastic injection mold assembly is disclosed in which an electric servo motor very precisely controls rotational speeds and amounts of torque applied to cores which extend into the mold cavities as the cores are withdrawn from plastic components being molded and simultaneously directs the linear distances which the cores travel during such withdrawal. A method of accomplishing the molding of plastic components in this manner is also disclosed.
