The development of different techniques for injection molding that reduce costs by saving material, eliminating secondary operations, and allowing use of smaller presses is discussed. These developments were revealed at the Molding 2004 annual conference sponsored by Executive Conference Management in New Orleans. The developments show how to reduce part thickness over ribs without risking sinks, how to apply and cure coatings on multiple parts while they are still in the mold, and how to mold large multi-material parts without requiring oversized presses. In this respect, the techniques such as external gas molding (EGM), and in-mold painting have proven to be effective.
