Method for post-injection lamination to add a functional film to an optical lens

A method for laminating a functional film on to a thermoplastic injection molded lens. A thermally curable glue is deposited on the lens while it is still in the mold. A functional film is introduced and the mold is closed again. The heat from the mold and the clamping pressure thermoform the film a...

Beschreibung
Zusammenfassung:	A method for laminating a functional film on to a thermoplastic injection molded lens. A thermally curable glue is deposited on the lens while it is still in the mold. A functional film is introduced and the mold is closed again. The heat from the mold and the clamping pressure thermoform the film and cure the glue, in a lamination process. A functionally enhanced lens having a film intimately laminated on to one side.
