Casting Processes 

Our steel casting foundry utilizes multiple processes to match your project requirements.

Sand casting is our most versatile process for custom steel castings. It accommodates components from 10 lbs to 5,000 lbs and works well for both prototype and production volumes. Sand casting offers design flexibility and cost-effectiveness across a wide range of geometries.

Investment casting (lost wax) delivers precision steel castings with complex geometries and tight tolerances. This process produces superior surface finish and dimensional accuracy, often reducing or eliminating secondary machining.

Technical Specifications

Our steel casting capabilities include components from 0.5 lbs to 5,000 lbs per piece.

We hold tolerances from ±0.005" to ±0.015" depending on casting process, size, and geometry.

Surface finish ranges from 125 Ra to 250 Ra as-cast. Finer finishes are achievable through secondary processing.

Our steel foundry pours 100+ ferrous alloys including carbon steel, alloy steel, stainless steel, tool steel, and specialty grades.
