Material behavior on the micro level is very different than what traditional (macro-level) plastics engineering has taught us. It is widely considered that plastics in the molten state demonstrate non-Newtonian flow behavior and in the majority of cases, this assumption is correct and reliable. However, in the extreme shear environments of micro injection molding, shear thinning behavior is often pushed to the limits into a region sometimes referred to as “the second Newtonian plateau”.
In this webinar, we will discuss conventional plastics flow behavior and explore some of the phenomena that occur under extreme shear exposure. Real world examples of effects of these behavioral changes on the resultant molded product will be discussed to ensure that you can make the best decisions when choosing the material for your micro medical design.
Attendees of this webinar will learn:
How micro injection molding differs from conventional (macro) molding.
About polymer mechanics and how it might impact material selection for a micro medical device.
Both the limitations and opportunities with plastics in micromolding.
