What is Centrifugal Casting?

Centrifugal casting is a process that has been around for over a century. It involves pouring molten metal into a mold to create pipes using centrifugal force. Hence, how it got its name. 

Now used in so many industries, centrifugal casting has been mass-produced on a large scale to meet the need. What makes it so popular? Perhaps it is its high level of reliability and material soundness or maybe it is because these products are created with a high level of accuracy. 

Whatever the reason, centrifugal casting isn’t going anywhere - so let’s learn about it. 

What is Centrifugal Casting? 

Sometimes referred to as roto casting, centrifugal casting is a metal casting process that begins with molten metal being poured into a die mold that has been heated and is spinning at a rapid rate. The die mold will be oriented and designed in any type of configuration so that it can yield the desired outcome. For instance, the mold could be horizontal or it could be vertical. 

As the molten metal is poured into the spinning die, inertia carries the metal throughout the walls of the mold at high pressures. Between the spinning and this added pressure, you get a piece of metal that has been created under controlled solidification. 

The result is a metal lacking in impurities without any unwanted pockets or inclusions. 

Types of Centrifugal Casting

There are many different applications that rely on centrifugal casting. A few of the most common include sewage and water pipes, engine cylinders, brake drums, bushings and rings, gas pipes, street lamp posts, and industrial equipment. 

To meet the needs of so many different industries, there are three main types of centrifugal casting. 

• True centrifugal casting. True centrifugal casting is the basic process mentioned above. The downfall is that it is limited to cylindrical and otherwise circular dies. 
• Semi-centrifugal casting. The product of semi-centrifugal casting is solid instead of tubular. 
• Centrifuging. Centrifuging works to create asymmetrical products using high pressure. These molds are typically small in size. 

Benefits of Centrifugal Casting

Are you interested in the benefits of centrifugal casting for your applications? Are you curious whether or not it will make a difference? Those who rely on it do so because it has proven to be beneficial, high-performing, and high-quality. 

Below are a few of the benefits of centrifugal casting. 

• The molten metal solidifies from the outside to the inside. This is what allows it to get rid of any impurities and cavities 
• Affordable manufacturing
• Easily mass-produce symmetrical products
• Mechanical soundness
• Can be used with different types of metal
• Very minimal waste

With all of the advantages it brings, the life and endurance of the resulting product are increased. And that makes it a reliable option.
