The Real Cause of Multi-Cavity Mold Imbalances

by John Beaumont

A lesson on shear induced melt variations ends some confusion regarding balancing runner systems
for multi-cavity molds.

The Beaumont Effect is recognized as the source of mold filling imbalances and product variations in molds
with four or more cavities. The worst failures caused by the phenomena can be most easily (visually) recognized
in molds with 8 or more cavities. However, shear induced melt variations impact every injection molded
part, with a greater influence than most realize….
