Abstract
A method of in-mold coating utilizing an injection molding machine oriented to a horizontal parting line. At the beginning of the cycle the mold opens and a charge of liquid coating solution is deposited onto the lower mold insert. A ophthalmic wafer is deposited on the coating to spread it across the insert surface. The mold is closed and a pre-cure phase elapses before the thermoplastic resin is injected into the mold cavity above the wafer. The process provides coated and functionally enhanced lenses upon ejection from the molding machine.
