A system and method for controlling an actuator which actuates an axially displaceable pin valve of an apparatus for injection molding of plastic materials, where the control system includes an electronic control unit of the actuator which adjusts at least one among position, speed and acceleration of the pin valve, and a position sensor which detects a position of a plunger of the actuator and is operatively connected to the electronic control unit. The position sensor indirectly detects the position of the plunger of the actuator.

A misalignment sensing system for a molding structure and a method for using same. The molding structure includes a first component and a second component, at least one of the components being selectively repositionable between a closed configuration of the mold structure and an open configuration of the mold structure. The misalignment sensing system includes an alignment member including a male portion coupled to and extending from the first component of the molding structure, and a female portion defined in the second component of the molding structure, the female portion being configured to receive the male portion when the molding structure is in a closed configuration; and at least one sensor connected to one of the male and female portions and being configured to detect a deformation of any one of the male portion and the female portion, the deformation being induced by a misalignment of the molding structure.
