Large Centrifugal Castings
From crushing hard rocks and minerals to lifting heavy loads, large industrial machinery is constantly pushed to the limit. Improve performance and longevity with centrifugally cast metal parts from U.S. Bronze Foundry & Machine
What’s centrifugal casting?
Large centrifugal castings create finished products by pouring molten metal into a spinning cylindrical mold. The mold is reusable, and metal is poured through an opening at the top of the spinning mold. Inside of it are chambers with the desired product shape or features.
The centrifugal force generated from the rotation exerts pressure onto the molten metal, causing it to conform to the mold’s shape. When the metal cools and solidifies, the mold halves are separated, and the finished part is removed.
The Centrifugal Casting Edge
Centrifugal casting produces metal parts with optimum accuracy and minimal waste. The process is perfect for manufacturing round castings with an inside diameter.
There are many advantages to using centrifugal casting for the manufacture of cylindrical and circular parts. They include:
- Faster turnaround
- Large Flange Offsets
- Higher Quality
- Better production throughput
- Lower cost production process
- Flexibility in casting size envelope
- Inhouse Engineering and Design
The extreme pressures placed upon the mold during rotation cause lighter contaminants and impurities to separate from the denser metal. These impurities gather in the component’s bore, minimizing chances that voids, or porosity will form within the crystalline metal structure. The machining process can easily remove these impurities. As a result, the final product is materially sound and free from defects. With casting capabilities ranging from 1” to 158” diameter, there is no job too big or too small.
