Webinar - ORBITAL on July 29

Determining Optimum Injection Speeds Beyond the “Viscosity” or “In Mold Rheology” Curve.

Determining optimum injection speeds beyond the “viscosity” or “in mold rheology” curve. Additional Scientific Molding Techniques including cavity imbalance testing, velocity capability/injection speed linearity and the ability to transfer from the velocity control to pressure control phases (VPT response) will be discussed. Data will be applied to Hybrid, All-Electric, and Vintage Hydraulic machines.
