Abstract: There is disclosed a method (400) of ejecting a molded article (310, 312) from an injection mold (100). The method (400) comprises: during a second portion of the mold opening cycle of the injection mold (100), the second portion occurring later in time relative to a first portion of the mold opening cycle of the injection mold (100): controlling velocity of at least one of: (i) the moveable mold half (102, 502) relative to the stationary mold half (104, 504), (ii) the ejector (230) relative to the moveable mold half (102, 502); and (iii) an ejector actuator linked to the core insert (112, 114, 512, 514); and (iv) a stripper actuator that is linked to the stripper sleeve (116, 516); the controlling executed such that the molded article (310, 312, 506) is ejected from the molding component with a substantially zero departure-velocity along the first axis of operation.
