INVESTIGATION OF DIFFERING APPROACHES TO DETERMINE AN OPTIMUM INJECTION VELOCITY DURING MOLD FILLING

摘要

Injection fill rate may be the most important processing variable in the injection molding of plastic components. A comparative study was conducted to contrast Scientific Molding and computer simulation for determining optimum injection velocity. One method is based on the behavior of pseudo-plastic non-Newtonian fluids and the other on the predicted results of inputs for process settings by simulation software. Once optimum fill rates were determined they were evaluated against each methods standard to determine if one method is more advantageous than the other. Results suggest Scientific methods are more reliable.
