Aurora Metal's air-set sand foundry is designed to provide our customers with short- to medium-run castings. It allows us complete flexibility to produce castings in a variety of stainless steels, cast iron, and brass without the need for separate sand facilities for each material.

Air set sand molds allow closer as-cast tolerances with less mold wall movement and distortion, allowing superior repeatability on the smallest run quantities.

Our pattern shop and full-time patternmaker allow us to provide our customers complete in-house facilities for patternmaking. The pattern shop is also able to repair customer supplied tooling and prepare it for our sand casting process.

Our all-electric induction furnace facility allows casting of a broad range of alloys while exercising tight metallurgical composition control. Since quantities are job shop in number, each mold is handled individually and not treated as a run-of-the-mill assembly line product.

We have a complete sand testing facility to run screens, L.O.I.'s (loss on ignition) and tensile strengths for molding and core sands. Our lab spectrometers verify the chemical composition of each heat before and after casting. Patterns and intricate casting dimensions are verified on our coordinate measuring machine.

Casting weights range from 2 pounds to 250 pounds. Quantities for sand casting usually run from 1 piece to 500 pieces per month.
