Foundry Sand Testing

The foundry sand section of the lab focuses on evaluating the quality of sand used in metal casting.

• Grain size distribution: The grain size distribution test ensures that the sand has the correct texture and particle size to produce high-quality molds.

• Permeability: The permeability test measures the sand’s ability to allow gases to escape during the casting process, ensuring proper venting in molds.

• Strength and friability: This test assesses the durability and ability of the sand to withstand the mechanical stresses during mold preparation and pouring.

• L.O.I.’s (Loss on Ignition): The L.O.I’s test the amount of residual binder in reclaimed sand.

Spectrometer Analysis

• Elemental analysis: Our elemental analytics accurately determines the various elements in all iron samples.

• Quality control: Quality control checks ensure that the materials meet the specific alloy ASTM standards.

• Trace element detection: Trace element detection identifies and quantifies trace elements that can affect the performance of materials.
