Heat conduction controls Low shear rates, high local viscosities, and high flow resistance at low filling rates.

Due to the slow replenishment rate and slow flow of hot plastic, the heat conduction effect is more obvious, and the heat is quickly taken away by the cold injection mold wall.

Coupled with a small amount of viscous heating, the thickness of the solidified layer is thicker, which further increases the flow resistance at the thinner wall.
