APPARATUS AND METHOD FOR PRODUCING CENTER GATED LENS MOLDS FOR CONTACT LENS MANUFACTURE. |
摘要 |
Method and apparatus for the manufacture of lens molds used in the formation of optical contact lenses, the apparatus comprising a center gate aligned on the central axis of the lens mold cavity for delivery of the melt polymer in an axisymetrical manner. The methodology produces lens molds of extremely precise dimensions as measured against lens molds produced with side gated technology.
