TRIPLE-FLIGHTED SCREW ELEMENTS

Product Description
Materials & Properties
Processing. Knowhow

Product Description:

· Triple-flight screw elements, primarily finding utility in masterbatch production or for specialized materials like automobile bumpers. In comparison to modern counterparts, the three-flight screw element features shallower screw grooves for hosts with identical center distances. Its triangular cross-section creates three kneading points between the screw and the barrel, facilitating superior plasticization and enhancing the screw's efficacy in distributive mixing of modified materials.;
