Hot — Cadmould Vs Moldflow

CADMOULD (now Moldex3D) uses a True 3D Solid Solver exclusively.

Winner: CADMOULD for transient heat-up (first 10 shots). Moldflow for steady-state cycle simulation (shots 1001 to infinity). cadmould vs moldflow hot

| Capability | Cadmould | Moldflow | |------------|----------|----------| | Flow imbalance due to shear heating | Excellent — historical strength | Good, but less emphasized | | Nozzle drop pressure drop | Very accurate (1D + 3D hybrid) | Accurate in 3D, less in Dual Domain | | Valve gate hesitation / jelly effect | Handles well | Good, but needs fine mesh | | Temperature control during packing | Yes | Yes | | Gate freeze time prediction | Yes | Yes (more validated industry-wide) | CADMOULD (now Moldex3D) uses a True 3D Solid

Winner: Cadmould for shear-induced imbalance in hot runners. Winner: CADMOULD for transient heat-up (first 10 shots)

The biggest debate between these two software packages regarding hot runners is temperature prediction.
