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.
