We produce high-strength centrifugal castings with superior grain structure, achieved through controlled processing and precise execution. Our end-to-end centrifugal casting services support projects of all sizes while ensuring reliable performance and dimensional consistency.
During the process, molten metal is forced against the mould wall, allowing the material to spread evenly and compact efficiently. This method results in parts with finer metal grains, offering improved strength, corrosion resistance, and dependable mechanical properties. Centrifugal casting is commonly used to manufacture components such as discs, rings, cylinders, pipes, pulleys, wheels, and similar rotationally symmetric parts.
The vertical centrifugal casting process is employed for cylindrical shapes in which the diameter exceeds the height or length of the component. The horizontal centrifugal casting process is used for long cylindrical parts where the length significantly exceeds the outside diameter. Our centrifugal casting foundry handles both vertical and horizontal operations to meet varied production requirements.
This method does not require an interior mold core. The spinning of the symmetrical mold around its central axis causes the metal to disperse through the mold, forming a cylindrical casting with a hollow, rounded interior. True centrifugal casting is ideal for high-precision centrifugal castings. Metal parts produced using this process include engine cylinders, ring pistons, and pipes.
In this process, the addition of a central core to the mold determines the shape of the interior hole in the casting. The production process still relies on rotating molds to obtain finely grained castings. Products manufactured using semi centrifugal casting include flanges, sprockets, valves, propellers, track wheels, railroad car wheels, and flywheels. Calmet, as an experienced centrifugal casting company, ensures precision and superior quality in all semi centrifugal cast components.
This process involves spinning several small molds around a central axis, similar to test tubes rotating within a centrifuge. The individual molds grouped in this manner may include asymmetrical molds. Molten metal enters the mold through a central sprue and disperses throughout the interior via a network of pre-cut channels. Centrifugal casting is highly efficient for small-part centrifugal casting, producing gears, disc-shaped metal components, and other small parts with fine grain sizes.
Centrifugal castings are a specialized type of metal component created by spinning molten metal into a rotating mold, allowing the material to distribute evenly and form a dense, uniform structure. Our process allows us to create components that are strong, wear-resistant, and dimensionally precise, making them ideal for demanding industrial applications. As a trusted centrifugal casting manufacturer, we handle everything from standard cylinders and discs to complex custom designs. Our advanced centrifugal casting foundry gives us complete control over each stage of production, ensuring consistent quality and reliability.

Client Overview
A leading global oil and gas equipment manufacturer required high-precision stainless centrifugal castings for their critical subsea pipeline systems. These components had to meet stringent standards for corrosion resistance, high pressure, and extreme environmental conditions in offshore drilling operations.
Project Scope
The client needed large-diameter stainless steel components that could withstand harsh subsea environments while maintaining structural integrity and precision tolerances. The centrifugal casting process was identified as the best approach to achieve the required properties and dimensional accuracy.
Challenges
Complex Geometry: The components had intricate internal passages that required precision casting to avoid machining errors and costly rework.
Corrosion Resistance: The parts had to endure prolonged exposure to seawater and high-pressure conditions, necessitating the use of premium-grade stainless steel (ASTM A351 CF8M).
Large Size: The castings ranged up to 30 inches in diameter, requiring expertise in handling large molds and ensuring uniformity in such large components.
Tight Lead Time: The client requested delivery within 12 weeks to meet their project deadline, necessitating careful planning and efficient production management
Advanced Material Selection
Our engineering team at Calmet recommended using ASTM A351 CF8M stainless steel, known for its excellent corrosion resistance and mechanical strength, which is critical for offshore and subsea applications. This grade was ideal for withstanding both the mechanical stresses and the corrosive environment of saltwater.
Precision Centrifugal Casting
By employing the centrifugal casting process, we at Calmet ensured that the material was free from internal porosity and voids, delivering superior mechanical properties:
Centrifugal force during casting resulted in a dense, fine-grained structure, ideal for high-strength applications.
The ability to cast thin-walled sections enabled us to meet the complex geometry requirements of the component.
Automated control of mold rotation speeds allowed for precise dimensional tolerances, reducing the need for post-casting machining.
Collaborative Design Optimization
We collaborated closely with the client’s design engineers to optimize the mold design and gating system for this large casting. Finite element analysis (FEA) was employed to simulate the casting process and predict any potential issues with solidification and shrinkage.
Efficient Production Management
Given the tight lead time, we implemented a parallel production strategy using multiple casting machines simultaneously. This approach, combined with our in-house heat treatment and non-destructive testing (NDT) facilities, ensured that we maintained quality while adhering to the schedule.
