Transfer Molding

Transfer molding is a step up from compression molding.  In this technique, material is stored in a reservoir called a pot and is injected through a sprue into the mold cavity.  Since the cavity the material being transferred into is considered a closed cavity, flash is of less concern and higher precision parts are produced.  However, since this does feature an "injection" portion, transfer molding generates more waste, and has a higher mold cost than compression molding.    Transfer molding is typically the technique RT/Dygert uses when we produced rubber coated metal parts.
