Moisture Content Spec Check
Measured pellet moisture vs the resin's molding limit — the loss-on-drying verdict.
Moisture analyzers settle the dryer argument in five minutes: PET's 50 ppm limit and PC's 200 ppm are invisible to the eye and fatal to the polymer chain. Splay tells you it was wet; the analyzer tells you BEFORE the shot.
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 Moisture Content Spec Check
Moisture Content Spec Check computes the governing relationship compare LOD/Karl-Fischer reading vs the grade limit live as you type. Moisture analyzers settle the dryer argument in five minutes: PET's 50 ppm limit and PC's 200 ppm are invisible to the eye and fatal to the polymer chain. Splay tells you it was wet; the analyzer tells you BEFORE the shot. 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 Moisture Content Spec Check
- 1Enter your values — Measured moisture, Resin's molding limit (sensible defaults are pre-filled).
- 2Read the live results: Times over limit.
- 3Check the "with your numbers" line to see compare LOD/Karl-Fischer reading vs the grade limit substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
