What Is Sand Casting?
Sand casting is a versatile and cost-effective metal casting process that utilizes expendable sand molds to form metal parts in almost any alloy. With minimal tooling costs and the flexibility to produce both small and large parts, sand casting is ideal for prototypes, small runs, and large production quantities alike. This process is especially cost-effective for larger part sizes (over 20” in any dimension or more than 30 lbs).

Design Specifications
for Sand Casting
Our sand casting process delivers exceptional flexibility and precision, allowing us to create large, complex parts with reliable dimensional accuracy and durable surface finishes. This makes sand casting an ideal solution for heavy-duty applications and intricate designs.
Wall Thickness
Low-Pressure Process: Minimum wall thickness of 0.075”
Gravity Pour Process: Minimum wall thickness of 0.150”.
Draft Requirement
A minimum draft angle of 2 degrees is required for proper mold release, ensuring the integrity of the casting.
Surface Finish
Typical as-cast surface finish ranges from Ra 250 to 500 micro-inch; post-machining can achieve smoother finishes as needed.
Maximum Weight Capacity
Capable of producing castings up to 14 tons, allowing for large-scale components.
Sand Casting VS. High & Low-Pressure Die Casting:
Which Is Right for Your Project?
Sand casting is a versatile, cost-effective method for producing large and complex parts in almost any alloy. High-pressure die casting is best for high-volume, thin-walled components, while low-pressure die casting suits medium-to-large shapes with good surface finish. Sand casting excels when size, alloy flexibility, and design complexity outweigh the need for extremely tight tolerances or fine finishes. The table below outlines the key differences to guide your choice.
| Sand Casting | Low-Pressure Die Casting | High Pressure Die Casting | |
|---|---|---|---|
| Ideal for | Large, heavy, complex parts | Larger parts with superior quality | High-volume, thin-walled parts |
| Surface Finish | Ra 250-500 micro-inch | Ra 125 micro-inch | Ra 63 micro-inch |
| Typical Lead Time | 3-4 weeks | Lower | Higher |
| Wall Thickness | Moderate to thick | Moderate walls only | Thinner walls possible |
| Tooling Cost | Low | Moderate | High |
