6 Key Factors for Perfect Mold Cavity Balance - Nanoplas

The measure of how evenly a multicavity mold fills is called cavity balance. Multicavity molds aren’t as consistent as single-cavity molds, but since multicavity molds can usually produce parts at a lower cost, it’s essential to make sure the mold is designed for a balanced multicavity. If one cavity fills ahead or behind the others, the plastic in that cavity will process differently, resulting in a different part.
