摘要: A method and apparatus for the manufacture of optical polymer contact lenses in a closed mold, where a mold cavity is created between a front curve insert and a back curve insert, the side walls of the mold cavity being formed by the inner wall of a movable annular gate collar, the collar being positioned in a retracted position during polymer dosing and then moved prior to polymer cure into an extended position to complete the mold cavity and to separate the polymer curing inside the mold cavity from any waste polymer outside of the mold cavity.
