http://slidepdf.com/reader/full/xdsw-fusion-screw-ii 1/2

The Xaloy ® Fusion ™ II screw delivers enhanced chaotic mixing while retaining the

productivity benefits of faster plastication and lower melt temperature provided by

the original Fusion ™ screw. Like the original Fusion ™ screw, the Fusion ™ II has two

barrier zones. The first melts and meters the material forward to a homogenizing

transition zone. This zone is followed by a second barrier zone with an undulating

root profile providing intensive, chaotic mixing. The key difference between the

Fusion™ II screw and earlier models is that primary flights in the second barrier zone

have grooves. The new design is covered by U.S. patent no. 7,014,353, and has

also been applied for international protection throughout the world, in Asia,

Europe and South America.

The grooves in the flights allow materials

in adjacent melt channels to mix together,

thus enhancing the intensive, chaotic

mixing action produced by the screw’s

undulating root profile.

This further improves the dispersion of color and

additives in the melt and enhances melt homogeneity.

The Fusion ™ II delivers the same productivity benefits

as the earlier design. In injection molding, extrusion

and blow molding, the Fusion™ II can deliver increases

in plasticating rate of 15 percent and melt temperature

reductions of up to 10ºC compared with standard

mixing screws.

Typically, .5 to 1.0 MI LD/LLDPE blends

require 7 to 8 lb/hr/hp to process effectively.

The Fusion ™ II Screw was able to process

slightly more that 10 lb/hr/hp due to the

efficient use of available HP.

The Fusion ™ II Screw also features the added

benefit of energy cost savings through more

efficient use of available horsepower.

Resulting Overall Benefits

• More lbs/hr/hp

• Controllable melt temperatures

• Reduced energy costs

Xaloy recommends that a “hump” type

barrel zone temperature profile be used to

optimize the performance of the Fusion ™ II

Screw. Make sure that you request the best

temperature profile from your Xaloyrepresentative for your resin and process.
