METHOD AND APPARATUS RELATING TO INJECTION MOLDING CONTACT LENS MOLD HALVES
A contact lens mold half injection molding machine (60) comprises a plurality of tool cavities (54a, 54b), each tool cavity defining a space into which molten polymer can be injected so as to form a contact lens mold half (2, 4). The machine (60) also comprises an injection unit (103) in communication with the tool cavities (54a, 54b), the injection unit (103) being configured to melt a polymer and inject it into the tool cavities (54a, 54b). Further, the machine (60) comprises a controller (150). The plurality of tool cavities (54a, 54b) comprises a first subset of tool cavities (54a) and a second subset of tool cavities (54b). The machine (60) is configurable to injection mold contact lens mold halves (2, 4), by injecting molten polymer into the tool cavities (54a, 54b) and allowing the polymer to solidify, with one or more process parameters differing in value between the first subset of tool cavities and the second subset of tool cavities.
