Sand casting for durable, scalable iron, steel and aluminum components

Sand casting is a cost-effective process for producing durable parts at scale. Milson uses green sand, no-bake, and shell molding to support a wide range of component sizes and tolerance requirements.

Why OEMs rely on sand casting

Sand casting is one of the most widely used foundry processes because it balances cost, flexibility, and turnaround speed. It supports everything from structural parts to heavy-section components. For projects that require higher dimensional accuracy or smoother surfaces, we use no-bake molds or shell cores to improve stability and internal detail.

    Our sand molding processes

    We match each project to the most suitable molding process to achieve consistent results and efficient production. This range of molding options allows Milson to produce everything from large brackets and housings to precision internal passageways with repeatable performance.

    Green sand

    Cost-effective, flexible, and ideal for high-volume production. Supports medium-complexity shapes and general-purpose components.

    No-bake

    Stronger, chemically bonded molds that improve dimensional accuracy and reduce distortion. Suited for large, heavy-section castings and parts that need better surface stability.

    Shell molding and shell cores

    Resin-coated sand used to create rigid, high-precision molds and cores. Ideal for fine detail, smooth internal surfaces, and tighter tolerances.

    Where sand casting is used

    Milson uses green sand, no-bake, and shell molding processes to produce parts that are rugged, repeatable, and efficient at scale. Green sand supports high-volume production, no-bake provides stability and accuracy for large or heavy-section castings, and shell molding delivers fine detail and tight tolerances for complex features.
