Aluminum casting and machining from design to delivery.

Aluminum Sand Castings

Versatile and low cost, we offer dry sand casting and green sand casting processes for automotive, marine and commercial applications such as engine parts, food processing equipment, motor housings, pully wheels and runners, and dock cleats.

Permanent Mold Castings

This high quality, durable and lightweight solution is often the best choice for parts that require finer details and a higher surface quality. Often used to manufacture automotive aftermarket parts.

For finishing all of your castings, our high volume capacity ISO certified CNC Machine Shop manages projects with precision and speed. We support projects with tight tolerances and complex geometries.

Four Steps to Your Success

Bell Foundry’s design, casting and machining process has been crafted to deliver the highest level of engineering, production and customer satisfaction.


Expert engineers strategize with you to design the highest quality part using 3D modeling and simulation programs. perfecting your prototype and reducing your overall production costs and time to market.


We design and cast molds in either aluminum sand casting or permanent mold, then deliver them to our in-house machine shop for precision milling, drilling, tapping and boring. Our in-house teams eliminate the need for any outside vendors, saving you time, scrap and costs.

Quality Assurance

We use only certified and traceable ingots for aluminum castings. We verify the chemistry and microstructure of each heat, cataloging a metal sample in our own database and sending a copy of lab results to you.
