Custom Metal Casting Services: Metal casting is the process of pouring molten metal into a cavity mold and then cooling it to form a solidified part. Depending on the method you choose, metal casting can achieve very high production rates with little to no secondary operations.
Tooling affects the time and cost of a production run. Determining the size of your production run can help you find the right foundry. Shops often specialize in high-volume or low-volume production projects.
Common materials for metal castings include aluminum, steel, stainless steel, copper, zinc, magnesium, nickel, and various alloys.
Die Casting: A high-pressure process resulting in precise and repeatable parts.
Investment Casting: A traditional method using wax patterns for intricate shapes.
Permanent Mold Casting: Uses reusable graphite molds for high-precision repeatability.
Sand Mold Casting: Versatile methods including green sand and self-hardening sand casting.
