Abstract
A magnetic coupling for an injection molding apparatus, such as a hot half or hot runner, includes a first magnetic part for connection to an actuator, a valve pin plate, or the like and a movable second magnetic part for connection to a valve pin. The first magnetic part and the second magnetic part are coupled by a magnetic force. The first magnetic part can be part of the actuator. The second magnetic part can be part of the valve pin. A valve pin plate can be provided for a plurality of valve pins.
