Experienced Centrifugal Castings
Calumet Brass Foundry now has the ability to deliver high quality Centrifugal Castings. Centrifugal casting, or rotocasting, is a casting technique which has application across a wide range of industrial and artistic applications:

• It is used as a means of casting small, detailed parts or jewelry. An articulated arm is free to spin around a vertical axle, which is driven by an electric motor or a spring. The entire mechanism is enclosed in a tub or drum to contain hot metal should the mold break or an excess of metal be used. Single use molds are prepared using the lost wax method. A small amount of metal in a crucible next to the mold is heated with a torch. When the metal is molten the arm is released, forcing (by centrifugal force) the metal into the mold. The high forces imposed on the metal overcome the viscosity, resulting in a finely detailed workpiece.
  
  
• For industrial casting of small parts using poured hot metal, a disk shaped mold is contained within a rotating drum, and molten metal is poured into the center.
  
  
• Centrifugal casting is also applied to the casting of disk and cylindrical shaped objects such as railway carriage wheels or machine fittings where the grain, flow, and balance are important to the durability and utility of the finished product.

A Note On Lead
In 1995, Calumet Brass Foundry implemented many controls and operating procedures designed to minimize problems associated with lead handling. Lead remains an extremely beneficial material, including lubricating qualities crucial to areas where friction and wearability remain concerns (such as bearing and guide applications). Calumet Brass Foundry offers castings with up to 25% lead content.
