Centrifugal Casting
Create superior strength tubing with lower production costs
Specially designed for cylindrical parts, centrifugal casting begins with pouring molten metal in a rapidly spinning mold cavity, which drives contaminants to the center. Once the desired shape forms, impurities can be removed easily and tubing cut to exact specifications. This results in a number of advantages:
- Creates parts with a longer service life
- Lowers your manufacturing costs
- Maintains control over the physical properties
- Improves lead times and production flexibility
Over 45 years of experience matching tubing product specifications

Frequently asked questions about centrifugal casting
What’s the main benefit of using centrifugal casting?
Centrifugal casting produces more robust products with precise cylindrical shapes. The results yield higher stress tolerances than other casting methods. The extreme pressure of the process separates impurities from the denser metal minimizing the formation of weak points.
Does centrifugal casting produce a reliable part?
Because our centrifugal casting foundry uses the best alloy combinations from over 200+ choices, the base materials exceed your component’s required physical properties, resulting in better durability and reliability and contributing to overall longer service life.
How does centrifugal casting save money?
Because the base material starts out in hollow cylinder form and not as a solid, impurities are easier to remove from the center creating an overall reduced material cost. You’ll also see fewer rejected parts which make the entire process more economical and less wasteful.
Can centrifugal casting parts be delivered faster?
As a long-standing foundry, our molds are well-established and can be quickly set up with a shorter preparation time, reducing manufacturing costs and lead time.
