Hotspot Detection, Gating, Riser & Feeding Gravity Casting

Design Optimization · Feeding Strategy · Yield Improvement

Understanding Hotspots in Gravity Casting

In gravity casting, molten metal enters the mold cavity under the influence of gravity and solidifies progressively from the mold walls towards the center. During solidification, metal undergoes volumetric contraction. If the last solidifying regions do not receive sufficient liquid metal from a feeding source, shrinkage porosity and internal voids can occur.

These last-to-solidify areas are known as thermal hotspots and are generally associated with:

  • Thick wall sections
  • Heavy masses and isolated volumes
  • Junctions of multiple walls
  • Boss and flange connections
  • Sudden changes in section thickness
  • Areas with poor directional solidification
How Geo‑Designer Identifies Hotspots

Geo‑Designer uses Mass Distribution Index (MDI) analysis to quickly evaluate the 3D CAD model and identify thermal hotspots within minutes. The software predicts regions with high thermal mass that are likely to solidify last and require feeding support.
After adding riser & feeding system, MDI analysis verifies hotspot shift from casting into riser — confirming effective feeding.

Geo Designer Hotspot - Gravity Casting

Geo‑Designer hotspot analysis helps determine:

  • Whether a riser is required
  • Optimum riser location
  • Number of risers required

Hotspot Detection High Pressure Die Casting (HPDC)

Identify thermal criticality · Optimize die & process design

Understanding Hotspots in HPDC

In High Pressure Die Casting (HPDC), molten metal is injected into the die cavity at extremely high velocity and pressure. Although HPDC components are generally designed with thin walls and rapid solidification, local thick sections, heavy masses, rib intersections, bosses, and abrupt wall transitions can retain heat longer and become thermal hotspots.

These hotspots are the last regions to solidify and are highly prone to casting defects such as:

  • Micro-shrinkage and internal porosity
  • Surface sink marks
  • Gas-shrinkage interaction defects
  • Thermal stress and distortion
  • Variations in mechanical properties
  • Reduced pressure tightness and leakage issues
How Geo‑Designer Identifies Hotspots

Geo‑Designer utilizes Mass Distribution Index (MDI) analysis to rapidly evaluate the 3D CAD geometry and predict thermal hotspots by analyzing the mass distribution and solidification tendency of the component. The analysis is completed within minutes, allowing designers to make immediate design improvements before moving into die design and detailed casting simulation.
