The disclosed embodiments include a system and method for manufacturing a lens. In one embodiment, the system includes a lens mold. According to the embodiment, the lens mold contains a part cavity and a material flow path fluidly coupled to the part cavity and a lens material inlet. The system also includes a heat transfer insert. According to the embodiment, the heat transfer insert includes an insert surface positioned adjacent to a part surface of the cavity, a sealed fluid inlet, a sealed fluid outlet, and a conformal fluid conduit that extends from the sealed fluid inlet to the sealed fluid outlet.

This invention relates to the development of a multi-layer PC polar laminate and its cut and form process. The laminate displays increased adhesion between a PC film layer and an adjacent film layer. As a result of the increased adhesion, less adhesive may be applied between laminate layers, which positively affects PC cracking and mold cavity contamination.
