Custom Metal Casting Services

Metal casting is the process in which molten metal is poured into a hollow cavity mold and later cooled to form a solidified part. Casting is ideal for creating detailed parts that meet exacting specifications. Depending on the method you choose, metal casting can allow for a very high production rate with little secondary machining required. Our domestic and global partners work with all types of metals to produce castings using methods such as die casting, investment casting, permanent mold casting, and sand casting. 

Compass & Anvil has been a leader in global sourcing for over 30 years. We can help your company eliminate common challenges associated with production, including excessive freight costs, communication barriers with offshore manufacturers, material identification, scheduling, and more. Receive hands-on facilitation throughout the entire product development process to ensure all your needs are met. Check out our customer testimonials to see what others have to say about our service.

Custom Casting Considerations

Factors to consider for casting services include:

  • Quantity of parts/production run size
    • Tooling factors into time and cost for production runs. Advantages and disadvantages for each casting method can make choosing the best type of casting process difficult
    • Determining your production run size can help connect you with the right foundry. Foundries often specialize in high-volume or low-volume production projects
  • Custom requirements and industry standards
    • Let us connect you with casting manufacturers who understand industry standards and compliance for your casting application
  • Casting design
    • Work with vetted casting manufacturers who have the knowledge and expertise to design a custom casting that meets your specifications (with a cost-effective casting mold).
  • Casting material
    • The type of material you choose for your casting project will depend on your project requirements
    • Common materials used for metal castings include aluminum, steel, stainless steel, copper, zinc, magnesium, nickel, and a wide range of alloys
    • We can connect you with a manufacturer to meet all your material requirements

Precision Metal Casting Methods

There are several methods for molding metal through casting. The method you choose depends on the volume, complexity, and cost goals of your project. Compass & Anvil can help accelerate your production process by connecting you with a manufacturer who provides the right type of casting for your project, along with a full complement of finishing services, such as drilling holes, painting, polishing, and buffing.

Die Casting

Die casting is a four-step process that involves forcing molten metal under high pressure into a mold cavity, resulting in an accurate and highly repeatable casting method

Investment Casting

Investment casting is one of the oldest known metal-forming methods. In this process, the mold is formed around a wax pattern that is burned away when the molten metal is poured in.

Permanent Mold Casting

Permanent mold casting uses reusable graphite molds that are ideal for manufacturing high-precision components. Because they can withstand indefinite use, graphite molds can produce castings with accuracy, again and again.

Sand Casting

There are several types of sand casting, including green sand casting, skin-dried sand casting, dry sand casting and no-bake sand casting. Each of these options offers a different set of advantages.
