Abstract

Design for manufacturing (DFM) for precision glass molding (PGM) requires a detailed understanding of the molding process and the process used to manufacture the molds. PGM lenses and molds require a transition segment between the optical surface and the flat or flange of the lens/mold. These blend radii provide tool relief, reduce high stress concentrations, reduce load requirements, extend mold life, and improve overall moldability. The methods for designing these radii are reviewed and guidance for proper DFM for PGM is provided.
