Abstract: An injection molding apparatus for manufacturing an ophthalmic lens mold having a front surface comprising a lens forming portion and a rear surface, comprises a first molding tool and a second molding tool. The first and second molding tools are movable towards and away from each other between a closed position and an open position. In the closed position the first mold forming portion of the first molding tool and the second mold forming portion of the second molding tool define a cavity between them corresponding in shape to the shape of the ophthalmic lens mold. The surface of the second mold forming portion, at least in a central zone thereof, has a surface roughness Sa in the range of 0.3 μm to 2 μm, and a surface roughness Sz in the range of 10 μm to 50 μm.

Abstract: An apparatus for simultaneously manufacturing a plurality of plastic molds comprises:—an injection molding tool comprising a first and second molding tool halves and—a gripper tool comprising a plurality of gripper members to which suction can be applied. The first and second molding tool halves are movable into the closed position and into an open position.A front surface of the first molding members comprises recesses to allow the formation of pins projecting from the rear surface the plastic mold into the recesses to make the plastic molds adhere to the first molding members. The gripper tool is movably arranged only in a direction parallel to the first surface into the space formed between the first and second surfaces for transferring the plastic molds to the gripper members and out of this space again.

Abstract: A method of providing a male mold half for molding a toric contact lens at a predetermined target rotational orientation is disclosed. The method comprises the steps of: —providing the male mold half at a predetermined rotational orientation, —picking the male mold half up with a gripper having a central axis, —rotating the gripper with the male mold half about the central axis of the gripper by a predetermined rotational angle (α) towards the predetermined target rotational orientation, and —releasing the rotated male mold half from the gripper. Prior to picking the male mold half up, the method comprises centering the grippe and the male mold half relative to each other such that the central axis of the gripper and a central axis of the male mold half coincide.
