All rights reserved.Aluminum Die CastingShort Shot shows flow imbalance between 3 cavities.ABC Copyright © ESI Group, 2007. All rights reserved.Aluminum Die CastingTurbulence in front of gate causes porosity.Vents & Overflows opposite gate bleed out the gas porosity.Added vent & overflow Copyright © ESI Group, 2007. All rights reserved.Aluminum Die CastingFilling sequence shows last region to fill is at 180 degrees from gate.Overflow ingates at this point were increased in size to bleed more gas porosity. Copyright © ESI Group, 2007. All rights reserved.Aluminum Die CastingTangential gate fills along one direction (1 stream of fluid) which better allows us to place overflows to reduce porosity.Significant reduction in porosity (from 15%to less than 1%) (actual final gating design not shown for confidentiality).
