METHOD AND APPARATUS FOR DEMOLDING CONTACT LENS

摘要

Methods and apparatus for manufacturing contact lenses, including demolding contact lens mold assemblies (200), are described. The apparatus can include a curved wedge separator (130) having an increasing thickness circumferentially from a leading end (133) towards a trailing end (134), and an increasing radial thickness from an outer circumferential edge (132) towards a central axis. The apparatus can also include a driver (150). The method can include rotating the separator (130) around a concentric central axis and directing the separator (130) to wedge the separator (130) between or against one or more different mold portions of a mold assembly (200).
