Barrier Screws

The patented Xaloy® Fusion™ screw allows you to increase production and improve product quality in injection molding and extrusion process applications. Its design is the combination of proven barrier screw technology and a low shear metering section that provides chaotic mixing, reduced melt temperatures and improved throughputs.


How it works - Using our proven Barrier Design Technology

  1. The separation of melted polymer from unmelted resin protects the melt from additional shear.

  2. Next the homogeneity of these two melt differentials re-combines in a short metering section.

  3. Then the final melting is completed by means of second barrier section designed for multi-cycle chaotic mixing.
    Diameters available: 1.5" to 10"
