Injection mold design, method for in-mold coating of lenses, and coated lenses |
摘要 |
A method and apparatus for coating lenses within an injection molding machine having a concave optical insert with a perimeter edge that meets the receiver ring in an annular contact region. A channel is formed throughout the annular contact region. When molding a lens with the apparatus, and according to the method, a closed-loop coating containment lip is formed by the channel. After the lens has solidified and the mold is opened, a predetermined volume of coating solution is applied and the mold is re-clamped. A uniformly thin layer of coating is cured on to the convex lens surface by avoiding coating run off and preventing mold contamination.
