Polymer material characteristics, part design, mold design, and process all play a critical role in molding quality parts. This lesson focuses on the development and execution of a process development strategy for a single cavity lawn tractor pedal mold.
In this lesson you will learn: the step-by-step approach to achieving cycle time goals; why higher pressure at the end of packing and holding can cause molded-in stress; how a process team may determine that they can inject more slowly during process development and maintain a reasonable temperature range inside the mold; and why molten areas may warp when a part is ejected and how final warpage is dependent on whether the molten areas shrink evenly.
