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.

Faster Changeovers

Quicker color and material changeovers reduce downtime and increase productivity, leading to lower manufacturing costs and improved operational efficiency.

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.

Versatile Applications

Suitable for injection molding, extrusion, blow molding, LSR applications, 3D printing, rubber machinery, and corrosion-resistant environments.

Frequently Asked Questions

What makes the Posi-Melt™ MB Barrier Screw different than other Barrier designs?

The Posi-Melt^™ technology utilizes an increased flight pitch change to start the barrier section with the barrier starting on the trailing edge of the primary flight and catching up on the leading edge, forseeing every pellet to cross over the barrier land to exit, assuring exceptional melt quality and zero un-melts.

Is the Posi-Melt™ MB Barrier Screw easy to cleand and east to change materials and color?

Our design utilizes a powerful forward pumping design with perfect leading and trailing radii to assure that the channel is pressurized leaving no dead sports for meterial degredation.

Do you couple the MB Barrier with a mixing section?

In most every case, our MB Barrier design is coupled with our XLA mixing section to further homogenize the melt pool for a more perfect thermal and viscosity variation design.
