Understanding the impact of packing pressures on polymer flow is an important aspect of successful processing. Our goal in this lesson is to evaluate the predominant polymer flow during packing. We will take a detailed look at the areas of continuous polymer flow, specifically during packing and cooling.
Topics in this lesson include: modify filling-to-packing switch-over points and packing profiles, how to understand the predominant polymer packing flow path by evaluating tracer results, melt core, packing pressure and clamp tonnages, and volumetric shrinkage development.
