For those interested in Moldex3D but facing budget constraints, consider:
| Parameter | What to Look For | |-----------|-------------------| | Mold Temperature | Too low → higher thermal gradients. Try raising it by 5–10 °C and re‑run. | | Coolant Flow Rate | Uneven cooling → high local gradients. Balance the coolant network. | | Packing Pressure & Time | Low pressure → voids → higher tensile stress. Increase pressure or add a “packing hold”. | | Gate Location / Size | Gate too close to the high‑stress region. Consider moving it or adding a secondary gate. | moldex3d crack top
Moldex3D’s Design of Experiments (DOE) module makes it easy to vary multiple parameters simultaneously: For those interested in Moldex3D but facing budget
| Variable | Low | Mid | High | |----------|-----|-----|------| | Mold Temp (°C) | 70 | 80 | 90 | | Packing Pressure (MPa) | 80 | 100 | 120 | | Gate Radius (mm) | 0.8 | 1.2 | 1.6 | | Radii at Sharp Corners (mm) | 0.0 (sharp) | 0.3 | 0.6 | Balance the coolant network
Run a fractional factorial DOE (e.g., 2⁴⁻¹) and observe which factor most reduces the crack‑top value.
