Engineered for Superior Performance

Our patented Posi-Melt™ technology delivers unmatched melt quality and processing efficiency across all polymer types.

Patented Technology

Proprietary feed screw technology that alters flight pitch and root through the melting section, making them un-tangential to disrupt laminar flow for superior mixing.

Enhanced Melt Quality

Increases plastic exposure to barrel wall by up to 60%, delivering uniform homogenized melt with consistent temperature and material distribution.

Complete Pressurization

Complete pressurization throughout ensures excellent conveying, melting, and pumping performance with positive pumping angle and major flight OD wiping action.

High Throughput

Designed for low pressure drop and high throughput with appropriate leading and trailing edge radii to avoid low-velocity sections and maximize pressure.
