The applicability of the Cooper-Eaton equation for green sand molding was examined using various base sands under different bentonite additions. A quantitative analysis was carried out by evaluating the correlation between compaction behavior and morphological properties of sand to investigate the influence of grain morphology on sand compaction behavior. The rearrangement mechanism of compaction can be quantitatively related with four factors of the morphological properties of sand grain by using two linear equations. Among various parameters, shape factors, size and shape distribution of sand particles are shown to be significantly influential on the rearrangement mechanism.
