Injection Velocity Profile
Because plastic changes viscosity with injection rate, a processor must be in velocity control, not time or pressure limited. That means that you check the pressure at transfer (may or may not be peak pressure) during molding and you compare it to the pressure limit available on 1st stage (at all velocities).
Glossary
Viscosity... - Determined by dividing the average efflux time of the solution by the average efflux time of the pure solvent.

Melt Viscosity and Apparent Melt Viscosity...
Melt Viscosity is the ratio of shear stress to shear rate at a given shear stress or shear rate. Apparent Viscosity is the melt viscosity of a material exhibiting non-Newtonian behavior (ratio of shear stress to shear rate is not constant at a specified temperature and pressure). This article provides an overview of ASTM D3835 with links to resources, books and publications.
