Sand core quality begins with the sand mixture. Expert Cores uses QR code computer-controlled sand mixers to provide an infinite number of sand mixes and ensure consistency from batch to batch. Sand mixture consistency alleviates any guess work and ensures a core will perform as designed.
A dedicated Core Process Sheet follows every order to the production floor to guarantee sand cores exactly match customer specification.
Expert Cores has an internal sand lab to test tensile strength, and the lab regularly checks for loss of ignition to ensure sand mixer calibration. Expert Cores uses only virgin sand for all cores.
