A first rotation controller that rotates a rotary table by feedback control based on a rotation amount detected by a rotation amount detection unit and a second rotation controller that rotates the rotary table by the feedback control based on a distance detected by a distance detection unit are included and rotation control by the first rotation controller is switched to that by the second rotation controller at a predetermined rotation angle.

In a method for rotating a rotatable part (16) about at least one axis of rotation of a machine (10) for processing plastics and other plasticizable masses, in particular an injection-moulding machine having at least one movable segment (14) for producing at least one moulding, in order to optimize the movements of the machine (10), in particular the tool movements, and to save cycle time, but still with safe, gentle and low-wear operation, the movement of the at least one segment (14) is at least partially superimposed with the movement of the rotatable part (16), wherein the movement of the rotatable part (16) is started when the distance between the at least one segment (14) and the rotatable part (16) is greater than a moulding height of a moulding to be produced on the machine (10).

A method is provided for moving a movable mold mounting plate of a molding machine, in which the movable mold mounting plate is movable relative to a stationary mold mounting plate and the mold mounting plates are kinematically connected to each other, and in which a drive mechanism for moving the movable mold mounting plate is provided. Molding tool parts arranged on the mold mounting plates are brought into abutment to each other in a closed state, and a temporally changeable tilting movement of the mold mounting plates relative to each other occurs by the movement of the movable mold mounting plate. The movable mold mounting plate is moved by the drive mechanism and/or the stationary mold mounting plate is moved by an injection device in such a way that when reaching a predeterminable distance of the mold mounting plates relative to each other, a parameter representing the tilting movement of the mold mounting plates relative to each other is less than or equal to a presettable value, preferably equal to zero.
