Centrifugal Cast Bronze Blanks
Centrifugal casting ensures uniform purity, weight, density, and quality throughout the gear blank. These bronze gear blanks put the strongest material at the outer edge for gear teeth that can withstand exceptionally high levels of strain, shear-stress, and overload without fracturing.
We make them all from solid bronze—whether standard 907 bronze or many other bronze alloys to fit your application. Sizes range from 2″ to 50″ in diameter, up to 5,000 lbs.; one-off or in quantities in the thousands. Our centrifugal castings are specified for thousands of applications due to their superior strength and high-end performance.
Centrifugal Casting Process
Our centrifugal casting process produces bronze gear blanks with extremely high purity levels and finer, denser grain structure. By spinning the casting die at high speeds which produce pressure up to 60 times the force of gravity, all imperfections and impurities are forced into a center riser area. When cooled, the center riser material is machined out, and the resulting part is free of shrinkage cavities, gas pockets, and blowholes.
Advantages of Centrifugal Castings
Centrifugal casting ensures that the material will be uniform in purity, weight, density, and quality throughout. This manufacturing method also produces bronze gear blanks with the strongest material at the outer edge, leading to gear teeth that can withstand exceptionally high levels of strain, shear-stress, and overload without fracturing.
All of Accurate Specialties’ centrifugal castings are made from solid bronze—we work with standard 907 bronze and many other bronze alloys to give you the material option that best fits your application. Our manufacturing expertise enables us to produce cast bronze parts that match your exact designs. We can manufacture small to large centrifugal gears, in sizes from 2″ to 50″ in diameter, and up to 5,000 lbs. We can produce bronze gear blanks in quantities from one-offs into the thousands.
