ABSTRACT:
A method for designing a molding apparatus, especially for molding lenses and the like, comprises defining a nominal mold reference curve disposed bewteen a pair of mold members having smooth, curved surfaces in confronting relationship to define a mold cavity therebetween. A plurality of concave and convex molding members are provided, all having differing molding surface curvatures but identical spacing from the respective curved surface to the nominal reference curve, measured from the point of closest approach of the curved surface to the reference curve. Any paired concave and convex molding surfaces have the same spacing from the reference curve and thus from each other, so that, for example, a universal gasket can be employed to hold any two paired convex and concave molding members in precise spacing, without regard to the curvature of the molding surfaces.
