What are centrifugal castings?
Centrifugal casting, also commonly known as spin casting is typically used for industrial manufacturing of cast parts. The centrifugal casting process differs from others because it requires special knowledge and skills not usually found in other types of casting operations.
In the centrifugal casting process, molten metal is poured into a preheated cylindrical mold spinning about a horizontal or vertical axis at pressures approaching 100 times the force of gravity. This force distributes the molten metal and shapes it into a tubular/cylindrical form.
Improved Physical Properties
Because they are formed under pressures greater than those of gravity and are combined with directional solidification, parts produced by this method have a denser, finer-grained structure with greatly improved physical properties.
Due to the high structural uniformity, physical properties such as elongation, yield and tensile strength, area reduction and other desirable properties are improved by up to 30% over conventional gravity or static casting methods.
Qualities
Due to the finer grain and denser structure of parts cast with centrifugal there is an increased usage life, greater endurance and impact without fracturing.
The force used to distribute the molten metal when pouring is so strong that it displaces the lighter oxides and impurities to the center of the hollow cylinder. This makes it easy to remove these impurities during the machining process.
The centrifugal process enables economical production of a wide range of shapes, sizes, and quantities, resulting in extended life, reduced rejects, reduced manufacturing costs and production flexibility.
Our extensive inventory of molds eliminates the customer’s expense of purchasing, storing and maintaining patterns and due to the short mold preparation time required, delivery can be scheduled to meet the customer’s needs.
Quality control is a fundamental element of our business. Our proactive quality control starts from the receipt of materials and is maintained across the entire manufacturing process, up to the product or service delivery to our customer.
Our quality management relies on an integrated quality management system conforming to ISO 9001:2015.
A modern optical emission spectrometer is used to perform a complete chemical analysis. This process is part of our rigorous control routine to ensure that each casting meets our customer’s specifications.
In-house heat-treating reduces lead-time and ensures compliance with customers heat-treating specifications. Our process has the heat-treating capability to do water, environmental and air cooling depending on the specifications of our customers.
Disc saw cutting provides a faster, straighter and smoother cut than other traditional cutting methods.
We are genuinely interested in our customers’ requirements, and thus place great value on an open dialogue and collaboration, in order to create value for both parties. We give advice, and provide you with customized products and solutions to meet your requirements.
Each casting is inspected upon arrival from the foundry, at the completion of each machining operation and prior to shipment to the customer. Thorough inspection and quality control ensure that each part matches the customer’s exact specifications.
Do you have parts that you purchase on a regular basis? Let us design a stocking program based on your needs to help you reduce costs and lead times.
Let’s work together on your next project!
