Knobs, Handles, and Custom Molding

Davies Molding has been providing top quality plastic knobs, handles, cases and custom plastic components since 1933. We are the largest molder of insert-molded knobs and handles, and have tremendous flexibility with our injection, compression and transfer presses to mold both thermoset and thermoplastic components.


Originally located in downtown Chicago, Davies Molding was then known as, and is still regarded today by some, as “The Harry Davies Molding Company” after owner Harry Davies. Today, we have over 9000 standard knobs, handles, and cases for you to choose from.  Can't find what you're looking for?  We also mold custom plastic parts for the automotive, food services, oil & gas industries, and more.  Check out our product portfolio to learn more about our molding capabilities.
