Casting Process Control: Why Consistency Isn’t Enough

Abstract Casting process control is often defined by repeatability—fixed parameters, standard procedures, and consistent simulation outputs. However, repeatability does not guarantee stable results. In practice, many casting processes that appear consistent still produce variable outcomes. Defects move, porosity appears intermittently, and mechanical properties fluctuate. This article explains why casting defects vary even in “controlled” processes … Read more

The Simulation Didn’t Change — The Process Did

Casting simulation is deterministic. If the geometry, material properties, and boundary conditions are unchanged, the simulation will always predict the same result. The fill pattern will be the same. The solidification path will be the same. The last-to-freeze location will be the same. The predicted shrinkage will be in the same place every time. Yet … Read more
