Abstract
An apparatus for injection molding thermoplastic material has mold halves carried by stationary and movable mold mounting plates which are mounted on a frame. A control mechanism actively applies a variable torque to one of the mold mounting plates for compensating for any bending of the frame due to the closing force applied between the mold halves.
