An apparatus and method for adjusting the axial position of a valve pin in an injection molding system, the apparatus comprising: an actuator comprising a housing having a chamber enclosing a drive member for driving a valve pin along an axial path of travel, the actuator housing slidably mounted and adapted for controlled upstream and downstream movement of the drive member along a path complementary to the axial path of travel of the valve pin, a mounting plate and an axial position adjustment screw screwably mounted within the mounting plate upstream of the housing of the actuator for controllably moving the valve pin to selectable starting or ending injection cycle axial positions.

A method for creating optical articles includes moving first and second mold portions relative to one another. This disclosure includes injection molds for reducing cycle times and related methods. Some molds include first and second mold portions movable relative to one another from open to closed positions in which each recess of the first mold portion cooperates with a respective recess of the second mold portion to define a chamber. Each chambers includes a first cooling body coupled to the first mold portion, a second cooling body coupled to the second mold portion, and first and second inserts removably coupled, respectively, to the first and second cooling bodies. The inserts cooperate to define a mold cavity within the chamber configured to receive a thermoplastic material. Each of the cooling bodies has an inlet, an outlet, and a fluid cavity in fluid communication with the inlet and the outlet.
