U. S. Silica Foundry Lab Resin Bonded Sand Testing Capabilities

The U. S. Silica Foundry Lab performs Cold Box, Nobake and Warm/Hot Box resin bounded tests to assist our foundry customers in evaluating resin and sand performance. The Foundry Lab maintains a cache of USS foundry sands, resins and veining additives for testing. To ensure emulation of foundry conditions, the Foundry Lab is equipped with a humidity chamber to mimic resin bonded sand performance in hot, humid conditions as well as cool, dry conditions.

The Cold Box uses DMEA to cure the cores and is purged with air, though the unit is also capable of being purged with Nitrogen or CO₂. In addition, the Gassing and Purge Times can be adjusted to emulate conditions established at a given foundry.

In addition to performing strength, density and permeability evaluations of resin bonded sands; the Foundry Lab has the capability to make Cold Box or Nobake Cores to be used for the evaluation of finish for both iron and aluminum castings and veining in iron castings.

The Foundry Lab also has the equipment to evaluate resin-coated sands.
