Our Centrifugal Casting Process

Mold Preparation

A cylindrical mold is selected or created based on the desired dimensions of the final product. These molds are typically made from steel or other durable materials to withstand high temperatures.

Preheating the Mold

To avoid thermal shock when molten metal is added, the mold is prepared to a certain temperature. This step also helps achieve better surface quality and reduce defects.

Pouring the Molten Metal

Molten metal or alloy is poured into the rotating mold. The mold is spun quickly, usually on a horizontal or vertical axis. The molten metal is forced up against the mold's inner walls by the centrifugal force created by this spinning.

Forming the Casting

As the mold spins, the centrifugal force ensures that the molten metal fills the cavity uniformly, forming a dense and homogenous casting. Any impurities or inclusions are pushed towards the center, where they can be machined out later.

Cooling and Ejection

Once the metal has fully solidified, the mold is stopped, and the casting can cool further. The casting is then ejected from the mold.

Finishing

To get the final specifications and intended qualities, the cast part is put through a variety of finishing procedures, including machining, heat treatment, and surface treatments.

Custom Centrifugal Casting Solutions at Frigate

Centrifugal casting allows us to create pieces tailored to each part’s needs. Without cores, we can produce items of any length, thickness, or diameter. This method ensures parts have rotational symmetry due to gravity, resulting in seamless and large-size components. The production cost is low because molds can be reused for parts with varying wall thicknesses. This casting is less appropriate for pieces that need unique shapes because it is usually used to make stock materials. Only cylindrical shapes can be made, and there may be a considerable wait time.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

What is the role of centrifugal force in centrifugal casting?

Centrifugal force helps to push molten metal against the mold wall during casting. This force creates a strong, dense material and reduces the chances of defects like porosity. The faster the mold spins, the greater the force, which improves the quality of the final product.

How does the cooling rate affect the properties of centrifugal castings?

The cooling rate in centrifugal casting is crucial. Faster cooling can lead to finer grain structures, which enhance strength and hardness. Slower cooling can result in larger grains, affecting toughness. Controlling the cooling rate helps achieve the desired material properties for specific applications.

What types of molds are used in centrifugal casting, and how do they impact the process?

Centrifugal casting uses two main types of molds: permanent and expendable. Permanent molds are metal and can be reused, while expendable molds are made from materials like sand. The choice of mold affects the surface finish and dimensional accuracy. Metal molds generally provide better precision.

Why is it important to consider the metal’s viscosity during centrifugal casting?

The viscosity of molten metal affects how well it fills the mold. Low-viscosity metals flow easily, ensuring complete mold filling and better details. High-viscosity metals may struggle to fill the mold, leading to defects. Selecting the right metal and temperature is essential for a successful casting.

How can centrifugal casting be used for complex shapes or thin-walled components?

Because of the centrifugal force, centrifugal casting is effective for creating complex shapes and thin-walled components. As the mold spins, the molten metal helps fill intricate details. This method allows for precise control over wall thickness, making it ideal for parts like pipes and tubes.
