摘要： The mold comprises two dies mounted in a sheath to slide along the axis of the sheath and each presenting a forming face facing the other. The two dies and the sheath are provided with intrinsic heat transfer means. A parison or preform of said thermoplastic material is placed between the two dies and the assembly is enclosed in the sheath; the dies and the sheath are heated by their intrinsic heat transfer means up to a forming temperature. The dies are moved towards each other to shape the material by plastic deformation until a predetermined relative position is reached corresponding to the thickness desired for the lens; the dies and the sheath are cooled by their intrinsic heat transfer means down to an unmolding temperature; and the finished lens is extracted from the mold.

摘要： 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; and bringing 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.

摘要： 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.
摘要翻译：公开了注射模制树脂（如聚碳酸酯）以形成固体光学透镜的方法。这些镜片非常适合用作非常薄的涂层载体。该方法包括用小于在注射期间施加在插入件上的力的夹紧力来闭合模具。在注射期间，允许模具呼吸，从而克服与注射成型非常薄的透镜相关联的许多障碍物。当注射压力降低时，模具开始关闭以进行压印操作，导致强大的高产量载体或透镜。

摘要： 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.
