(Barrier) Screws

Some types of polymers struggle to melt, or a higher quality melt is needed in their processing. We producer Barrier and Maillefer type screws to prevent the occurrence of such problems and to achieve a better melt quality. Barrier pitch screws orient polymer to two different channels during processing: melt and solid phase; they also force polymer to skip a narrow gap, which leads to the obtainment of a faster and more efficient melt. The relevant phenomenon allows the material to melt quickly and to mix in a dispersive manner. When barrier pitch screws are used with groove barrels, capacities 30 to 60% higher than traditional screw and barrel designs are achieved.

Advantages provided to you by barrier type screws,

Fixed and high output efficiency when compared with traditional three-zone screws

Better melt quality and lower melt temperature,

Minimum pressure and melt temperature change,

Better dispersive mix,

Much better processing of regenerated or scrap materials.
