Process & QC — Mold Vent Depth
Mold Vent Depth for injection molding process control.
Trapped air burns parts (dieseling) and shorts corners — vents cure both, sized just under the resin's flash threshold. Low-viscosity nylons flash through 0.02 mm where stiff PC needs it; vent depth is a resin property expressed in steel.
Formula
Note: Starting-point process values — the resin grade's datasheet and an in-mold study govern. Verify with a gate-seal study and a cooling-time ladder on the actual tool.

About Process & QC — Mold Vent Depth
Process & QC — Mold Vent Depth computes the governing relationship depth by viscosity class (0.010–0.025 mm); vent ~25% of the perimeter live as you type. Trapped air burns parts (dieseling) and shorts corners — vents cure both, sized just under the resin's flash threshold. Low-viscosity nylons flash through 0.02 mm where stiff PC needs it; vent depth is a resin property expressed in steel. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
How to use Process & QC — Mold Vent Depth
- 1Enter your values — Resin (1 PP/PE · 2 ABS/PS · 3 PC/PMMA · 4 PA/POM), Cavity perimeter to vent, Vent land width each (sensible defaults are pre-filled).
- 2Read the live results: Vent depth, Vents (25% of perimeter).
- 3Check the "with your numbers" line to see depth by viscosity class (0.010–0.025 mm); vent ~25% of the perimeter substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
