COMPUTING AN INJECTION FILL SPEED FROM A RELATIVE VISCOSITY CURVE

摘要

On-machine rheology is a methodology of determining the flow characteristics of a material at a given temperature with a specific mold and machine. This methodology can be used to help determine the best injection fill speed to be used for a given material, machine and mold combination. This study presents a mathematical method to obtain an injection fill speed starting point when setting up a new mold, machine and material combination.
