Question

In mold-filling procedures of metal casting, what are some important factors) as discussed in the lecture? Answers 1 Filling methods (top-down or bottom-up) Filling speed Viscosity of the molten metal Filling amount All of the above In injection molding of plastics what happen to the velocity when both shear strain rate and temperature increase? Answers Velocity is independent of shear strain rate and temperature Velocity increases as shear strain rate increases and decreases as temperature increases Velocity decreases as shear strain rate increases and increases as temperature increases Velocity decreases as shear strain rate increases and decreases as temperature increases Velocity increases as shear strain rate increases and increases as temperature increases What are some manufacturing processes for making fiber composites? Answers Resin transfer molding Filament winding Press-forming Pultrusion All of the above
