Students gain an understanding of how temperature, flow, and cooling affects the flow characteristics of injected polymers.
Class discusses:
Newtonian and non-Newtonian and the difference.
Viscosity of the polymer and its effects.
Thermoplastics and thermosets and their effect on polymer flow.
Processing regrind vs. virgin materials and the difference in the way they flow.
How temperature affects polymer flow.
Shear stress and shear rates and their effect on the plastic.
Amorphous polymers vs. semi-crystalline polymers and the effect each have on the polymer’s ability to flow.
