Bulk conversion at end of process result

    The Bulk conversion at end of process result is generated from a Midplane and Dual Domain Reactive Molding analysis, and shows the average material conversion (cure) across the part thickness, calculated at the end of the filling phase.

    Using this result

    Premature conversion is a typical molding problem and occurs when the material solidifies (cures) in the mold cavity before the curing phase is complete. If the material pre-cures, you will see an acceleration of the melt, followed by strong hesitation, that is, viscosity suddenly decreases because material is too hot, then abruptly increases as material pre-cures.

    If pre-cure occurs, increase the specified curing time until conversion throughout the entire part reaches the recommended Ejection conversion value for the material.

    TipThis value is provided in the material database. To find the Ejection conversion value, right-click on the selected material in the Study Tasks pane, then select Details...

    Things to look for

    • The material continues to cure after the end of filling, until the end of the curing phase. Therefore, be sure to view the Bulk conversion result, which shows % conversion until the end of the curing phase.
