A Guide to Custom Casting Service


Custom metal casting service is the process of manufacturing metal components specifically according to customer requirements, such as drawings, material requirements, and mechanical properties. It’s the most prevalent type of service required by many machinery manufacturers. Custom casting services are usually provided by OEM foundries or OEM casting companies, who can choose the right process and craft unique molds based on client needs.

Custom casting service has various applications in various industries, such as mechanical, automotive, renewable energy, and construction industries. The manufacturing volume can vary from as low as one piece to tens of thousands of pieces per year.

3. Process selection and quotation

Based on the annual usage and mechanical characteristics of the castings, select the most cost-effective casting process for customers and provide detailed quotations.

4. Mold development

Custom metal casting molds, start mold development after confirming the process and quotation to ensure accurate manufacturing of parts. Make sure to choose the best mold material to ensure its longevity.

5. Production Planning

Develop production plans according to customer delivery requirements to meet customer needs to the greatest extent.


6. Sample production

Usually before mass production, the foundry will mail samples for testing to ensure that the casting quality meets customer expectations.

7. Sample testing

Conduct various tests, including but not limited to material testing, coordinate measurement, X-ray testing, magnetic particle inspection and sampling testing to ensure parts meet high standards.

8. Report provision

Provide comprehensive test reports to ensure transparency and credibility of the partnership, such as PPAP/ISIR reports.

9. Sample transportation and mass production

The foundry ships the samples to the customer. After customer qualification testing, mass production is launched to ensure stable quality.

10. Delivery Services

Provide door-to-door comprehensive transportation services to create the most convenient conditions for customers and ensure on-time delivery.

Distinguishing Custom Metal Casting from Conventional Casting

Casting is an ancient manufacturing process, traditionally called the lost wax method, which is more suitable for the production of some small parts. However, the traditional metal casting process has certain drawbacks and cannot meet the needs of modern industrial development. Modern customized casting services can more flexibly meet the different needs of customers.

The modern casting industry is developing rapidly, and different casting processes are also developing in diversification. The parts produced by investment casting have extremely high surface finish and are suitable for producing parts with complex shapes; sand casting is a casting process for large parts, and the parts produced The surface is slightly rough; vacuum casting is a unique process that can reduce the content of gases and impurities, which is beneficial to improving the surface finish of the casting; low-pressure casting is to heat the metal alloy to a liquid state and inject the liquid metal under relatively low pressure into the mold; shell mold casting is a process that can achieve a balance between precision casting and sand casting. Under the premise of ensuring the surface finish of the product, shell casting can produce large parts and reduce the production cost of small parts.

Die casting is a high-pressure casting process that uses high pressure to quickly inject molten liquid metal into a mold to create high-precision parts. High-pressure injection molding can greatly improve the surface finish of parts, and can ensure the smoothness of parts with extremely complex shapes. This process is suitable for producing automobile frames and casings for electronic equipmen.

Centrifugal casting is a casting process specifically for hollow tubular parts. The casting method of this process is very special. It uses centrifugal force to uniformly solidify the liquid metal in the mold while the mold is rotating at high speed. The hollow parts cast by this process have uniform density and high precision. Usually used to cast pipes or wheel hubs with superior performance.

Continuous casting is a very efficient casting process suitable for large-scale mass production. Molten metal is directly injected into a continuous blank. During the injection molding process, the molten metal is cooled and solidified by a water-cooled copper plate. This continuous casting method has the advantage of high efficiency and is usually used in the production of plates or pipes.

Each process has its unique advantages and scope of application. In the process of providing customized casting services to customers, engineers will select the appropriate process for the customer based on the customer’s demand for output and the application scenario of the parts, while ensuring product quality. Under the premise of planning the most cost-effective production plan for customers.
