Hesitation

    Table of contents
    No headers

    The slowing down of the flow front due to preferential material flow through other, less restricted areas of the mold cavity.

    In a part with multiple flow paths, the flow can slow down or hesitate in thin regions. This condition enables the melt to cool and in some cases freeze before filling is complete, causing short shots. Flow hesitation is most likely to occur in parts containing thin diaphragms, ribs, and hinges.
