... was been removed through molecular relaxation. 26 This is particularly true of the surface of the part, where hot material reaches the cool walls of the mold with rapid solidification coupled with the ... degree of crystallinity. As the cooling rate increases, the degree of crys- tallinity will decrease. 28 Cooling rate effects can cause a gradient of crystallinity across the th...
