Avoiding and solving injection molding problems using shear rate calculations-Part 1

摘要

Many of the challenges faced in molding can be addressed by returning to the basics of how a material moves through the nozzle,gate,and mold.In the first part of this two-part series,we take you through the physics of resin behavior.Stay tuned for part 2 next month,when we'll give you the not-so-secret formulas for calculating shear rates.
