Tool Design: Balanced Runners

  • Symmetrical Layout

    – Equal flow length to all cavities
    without gate or runner correction
  • Layout in Series

    – Less runner scrap

    – Need to balance by changing
    runner segment dimensions

    – May be difficult when changing
    material

  • Circular Layout

    – Limited number of cavities
