3 Types of Centrifugal Casting

Centrifugal casting is a process that can be used to produce high-quality, complex shapes with a variety of metals and alloys. It is a type of permanent mould casting, meaning that it uses a reusable mould or die to shape the molten metal as it cools. There are several types of centrifugal casting, each with its own unique characteristics and benefits. Let’s take a closer look at some of the most common types.

Centrifugal Sand Casting

Centrifugal sand casting is one of the oldest forms of casting, dating back centuries. In this process, liquid metal is poured into a sand mould and allowed to cool before being removed. The sand mould itself is made up of two parts—a core and an outer covering—which are then combined together in preparation for the molten metal to be poured in. Once the metal has been poured and cooled, it must then be removed from the sand mould. This type of centrifugal casting is perfect for producing high-volume parts with tight tolerances due to its ability to absorb shock loads.

Centrifugal Shell Casting

Shell centrifugal casting differs from other forms in that it uses a thin-walled shell mould instead of a sand mould. This type of casting offers a higher strength than sand moulds due to the increased wall thickness, as well as a better surface finish due to reduced porosity and fewer blemishes on the finished product. It also results in lighter parts because there’s less material needed for support when using a thin-walled shell mould versus a traditional sand mould fabrication process. Shell centrifugal casting is often used for producing small components such as gears, pistons, valve bodies, and more.

Vacuum Centrifugal Casting

Vacuum centrifugal casting (VCC) combines traditional centrifugal casting with vacuum technology in order to produce components with improved mechanical properties, such as greater tensile strength or fatigue resistance, compared to traditional methods alone. This process starts by melting down the desired alloy in either an induction furnace or arc furnace before pouring it into the rotating die cavity, where it’s subjected to vacuum pressure while cooling down. Vacuum centrifugal casting can be used for manufacturing components like turbine blades or aircraft engine components that require extremely high levels of precision and strength due to their critical application requirements.


Centrifugal casting has come a long way since its early beginnings centuries ago; today, there are multiple variations available depending upon what kind of component you need to be produced and your specific industry standards or requirements for production materials, such as strength or durability. From traditional centrifugal sand casts all the way up through advanced vacuum centrifuge casts, these various techniques offer something unique for whatever project you may have on your hands! Whatever your needs may be, understanding each type’s capabilities will help you make an informed decision about which method will be best suited for your project’s success!
