Sand Foundry Casting


Aurora Metal's air-set sand foundry is designed to provide our customers with short- to medium-run castings. Itallows us complete flexibility to produce castings in a variety of stainless steels, cast iron, and brass withoutthe 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 superiorrepeatability on the smallest run quantities.

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

Our all-electric induction furnace facility allows casting of a broad range of alloys while exercising tight metallurgicalcomposition control. Since quantities are job shop in number, each mold is handled individually and not treatedas 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 formolding 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 500pieces per month.
