Superior Surface Finishes

Aluminum Castings with Exceptional Surface Quality

Aluminum castings need to perform at the highest level while looking exceptional too. We achieve both with our specialized green sand molding process using oil-bonded Petro Bond sand. This process delivers consistent mold compactability, creating smoother, more reliable surfaces. Across the industry, Petro Bond stands out for producing casting finishes superior to many other methods.

Frequently Asked Questions

What is Air Set Molding in aluminum casting?

Air Set Molding is a process that uses chemically bonded sand molds, allowing for more intricate designs, deeper draws, and greater dimensional accuracy compared to green sand molding.

Air Set Molding is ideal for larger castings, complex geometries, and detailed features that cannot be achieved with traditional green sand processes.

With versatile tooling options, Air Set Molding supports both low-volume runs (a few parts) and high-volume production (tens of thousands of castings).

This process is widely used in aerospace, automotive, industrial machinery, and energy sectors, where precision and strength are critical.

Yes, we provide in-house heat treatment services, ensuring quality control and faster delivery without relying on third-party vendors.
