Vibration Dewatering and Slurry Leveling in Molded Pulp: Letting Slurry Fill the Mold Evenly

Vibration dewatering and slurry leveling are key to forming uniformity in molded pulp. Vibration spreads slurry evenly across the mold so fibers deposit uniformly, while leveling control avoids localized thick/thin spots, keeping wall thickness and strength consistent.

The Scenario: Three challenges in leveling

Molded-pulp leveling has three challenges:

Pain Points

• Uneven slurry deposit piles fibers locally, making wall thickness uneven;
• Deep cavities and corners are hard to fill, causing shortages or thin spots;
• Uneven dewatering means large moisture differences and unstable forming quality.

The Solution: Three leveling-control points

Vibration dewatering leveling has three points:

1. Vibration leveling Use vibration to keep slurry flowing evenly and avoid local fiber pile-up.

2. Multi-directional dewatering Arrange suction holes and vacuum reasonably to dewater deep cavities and corners evenly.

3. Stable slurry concentration Control slurry concentration and fluidity so fibers deposit uniformly.

The Result: Even wall thickness, stable strength

With leveling control done right, fibers deposit evenly and wall thickness is consistent, stabilizing strength and cutting defects.
