Metallurgical Lab and Product Control

Testing in our advanced metallurgical lab assures the quality and chemistry of each casting component. Micro structure analysis on a Spectrometer ensures the castings produced always meet required specifications.

Test bars are poured and machined for testing the mechanical properties as per specified standards. Each part is marked with a heat code for complete traceability down to mold and impression numbers.

Sand Control

Sand properties are monitored with the Hartley Compactability Systems on each of our mold lines. The manual tests conducted in the lab serve as backup to those readings to insure the best quality molds are available for the castings to be poured.

Sand Laboratory:
  • (1) Dietert – Sand: Strength/Compression, Permeability, Clay, Sieve Analysis Testers
  • (1) Mettler – Gram scale and O’Haus – Electronic scale
  • (1) Blue M – Muffle furnace
