3D study of cooling system effect on the heat transfer during polymer injection molding
TLDR
In this article, the effect of the cooling system design on the solidification and heat transfer of polymer by injection molding was studied. But the authors focused on the cooling of the polymer material by cooling water flowing through horizontal six cooling channels, and the results indicated that when the cooling channels approach to the product surface, the cooling efficiency increases.About:
