What is Compactability?
Compactability relates to the reduction in volume of sand bonded with clay and water after undergoing compression applied by squeezing or compaction.
What is the ideal range for compactability?
Compactability should ideally lie in the range of 36-42.
Why is it important?
Compactability plays an important role in producing good quality molds and castings. It affects sand fill and mold density in the pockets of pattern. It also affects the integrity of mold edges and corners.
