O&D’s own in-house foundry offers centrifugal castings ranging from 2″ to 44″ in diameter in a wide variety of bronze allows. We can customize your metal needs by using your unique chemical specifications provided to us. We cast using a no-bake sand casting and solid mold casting methods to further serve your needs. We stock a variety of bronze alloys on site. 

We supply copper based Rough-Turned/Rough-Bored (RTRB) castings in a variety of sizes, quantities, and alloys with a quick response time. We conform these castings to your specifications with an additional ⅛” stock added to save you machining time and material cost. With our clean, modern foundry facilities, we serve as an in-house material supplier to our own finished machines.
