Why It Matters:

• Unbalanced fill causes overpacking in early cavities, short shots in late cavities
• Higher reject rates and longer cycle times

Manual Balancing Method:

1. Run short-shot experiments at 80-90% fill
2. Measure fill patterns
3. Weld shut the fastest-filling gate, recut to smaller cross-section
4. Iterate until all cavities fill within 5% of each other

Flow Analysis:
Simulation predicts imbalance before cutting steel. Adjust gate size, runner diameter, and layout.

Melt Rotation:
Even geometrically balanced hot runners have "natural imbalance" from shear-induced temperature variation. Spiral mixing elements solve this.

Practical Tips:

• Add 10-15% extra runner length for future balancing
• Document each iteration
• For >32 cavities, consider staged filling
