Complete Guide to Sizing Injection Molding Machines: Why Materials Matter

In this video, The Complete Guide to Sizing Injection Molding Machines – Part 4: Why Materials Matter, Jason Holberg explains the critical role that material properties play in choosing and configuring injection molding machines. The session covers key factors such as crystallinity, viscosity, additives, density, and residence time, emphasizing the impact of each on machine performance and efficiency. Jason details the differences between amorphous and semi-crystalline materials, explains how additives like glass and UV stabilizers affect the molding process, and highlights the importance of accurate residence time calculations. This video is essential for engineers and operators aiming to optimize their machine settings based on material characteristics, ultimately improving production quality and reducing part rejections.
