Abstract: A mold half-block possesses at least one mold recess defined transversely by the working face of a shell provided with heat-transfer parts that are intrinsic and both-way (both heating and cooling), the shell including a base that receives all of the heat-transfer parts and a removable insert fitted on the base and carrying the working face, the insert having no intrinsic heat-transfer parts and being thermally regulated solely by heat transfer with the base. The insert is in the form of a cap which fits over at least a head portion of the base, and the heat-transfer parts of the base are allocated to the head portion of the base having the insert fitted thereover.

Abstract: For each lens molding cycle, the method comprises the following steps:raising the wall of the mold cavity to a heating temperature higher than or equal to the molding temperature of said material;filling the molding cavity with said material;at the end of filling, increasing the pressure of said material introduced in this way into the molding cavity up to a compacting pressure; andbringing the wall of the molding cavity to a cooling temperature to cool said molded material down to an unmolding temperature below its molding temperature, said cooling temperature being lower than said unmolding temperature.The molding cavity begins to be filled with said material before the heating temperature has been reached. Once both the compacting pressure of said material and the heating temperature of the molding cavity wall have been reached, they are both maintained for a given length of time.

Abstract: Methods are disclosed to injection mold resins, like polycarbonate, to form solid optical lenses. The lenses are ideally suited for use as very thin coating carriers. The method involves closing the mold with a clamp force less than the force exerted on the insert during injection. During injection the mold is allowed to breathe thereby overcoming many of the obstacles associated with injection molding very thin lenses. As the injection pressure subsides, the mold begins to close to perform a coining operation, resulting in a strong, high yield carrier or lens.

Abstract: A method for in-mold coating of an injection molded thermoplastic lens that resides in an injection molding machine oriented to a horizontal parting line. An optical lens is initially formed by injecting molten thermoplastic resin into an edge-gated lens-forming cavity held closed under a primary clamp force. The mold is opened at a time when the lens is rigid enough to retain its shape. An unpressurized full metered charge of coating is applied onto the center of the lens. The coating is co-molded by ramping up the clamp force from zero to a secondary clamp force less than the primary clamp force to compress the coating into a uniformly thick, fringe-free layer.
