Why Choose Sand Casting Over Die Casting or Investment Casting?
When it comes to selecting a casting method, aluminum sand casting offers unique advantages—especially for manufacturers who need flexibility, competitive pricing, and domestic sourcing. While die casting and investment casting have their place, sand casting is often the ideal choice for many industrial and commercial applications.
At Cast Metals Technology, we specialize in green sand aluminum castings, air-set aluminum castings and in-house machining, delivering quality parts with rapid turnaround and engineering support.

Top Reasons to Choose Sand Casting
✅ Cost-Effective Tooling
Sand tooling and sand molds can be made quickly and affordably, making this process ideal for prototyping, short runs and production runs.
✅ Wide Alloy Compatibility
We work with a broad selection of aluminum alloys to meet diverse mechanical and chemistry requirements.
✅ Ideal for Complex, Large Parts
Sand casting accommodates small simple parts as well as larger parts and complex geometries that die casting or investment casting may struggle with.
✅ Rapid Modifications
Need to revise a design mid-project? Sand casting allows for quick pattern/tooling changes without the costly tooling investment.
✅ Made in the USA
All tooling and castings are produced and machined in our U.S. facilities, ensuring supply chain security and consistent quality.
Is Sand Casting Right for Your Project?
Sand casting is often the best choice when:
- Your production volume is low to high volume range.
- Part complexity or size rules out other processes.
- You require fast lead times and flexible design changes.
- You need competitive pricing without sacrificing quality.
