Method of calculating the convective drying time for gypsum molds

Increase in the service life of forming surfaces of molding units. Part 1. Study of the improvement of molding unit forming surface material quality

“…If individual parts of a thick-walled mold set at a different time, as a result of heat liberation stresses may arise within the mold that may lead to formation of gaps between parts of the mold, and therefore the rate and uniformity of preform assembly will not be the same. This causes deformation of objects during drying and firing [34,35].…”
