The barrel blanks produced from these outstanding alloys are highly wear resistant and *can be used in your toughest applications.

How Do Barrier Screws Differ From Mixing Screws?


Mixing screws are designed to improve melt homogenization, including color dispersion. Barrier screws are designed to control the melting process.

The Reiloy USA Eagle Barrier screw combines the advantages of our patented Eagle mixer with the melting efficiency of the Reiloy USA Barrier screw design.

This combination equals a complete isothermal and homogenous melt quality.

The design of the barrier portion of the screw and the mixer itself is dependent upon the type of material being processed and whether the application is injection molding, blow molding or extrusion.

The patented Eagle is a low shear mixing screw that provides outstanding color mixing and melt quality without increasing melt temperature, burning or degradation while running at very high RPM.

The Eagle Mixing Screw has been proven to reduce part reject rates, improve production rates and reduce the amount of color concentrate required. This remarkable mixer has successfully processed commodity resins as well as engineering grade resins.

The Reiloy USA barrier features a solids channel approximately twice the width of the melt channel, separated by barrier flights.
This unique design provides efficient and controlled melting of the resin, especially the “hard-to-melt” crystalline materials.
