V. LaFay’s scientific contributions

For many years, researchers in the foundry industry and universities have been developing testing protocols to evaluate the physical, performance and emission characteristics of prepared green sand during pouring, cooling and shakeout. This paper will review the testing protocol and methods utilized in the collection and evaluation of these characteristics that is the result of the entire metal casting process. An important criterion also is the quality of the green sand mold and casting produced (defect free) when the emission characteristics are reduced. This paper will also include the laser imaging evaluation of the castings that is the result of the green sand foundry emissions.
