Abstract

In the method for molding the molded article for optical applications by injecting the transparent thermoplastic resin in a mold cavity, the transparent thermoplastic resin is injected into a mold (Th>Tc), whose temperature (Th) during heating is set to be higher by 0-100 DEG C than the deflection temperature under load of the injected thermoplastic resin and whose temperature (Tc) during demolding after cooling is set to be lower by 0-100 DEG C than the deflection temperature under load of the thermoplastic resin.
