Double Your throughput volume
in the Same Time<\/span><\/h2>\n<\/p><\/div>\n<\/p><\/div>\n
\n To improve manufacturing efficiency,
the quickest path is to reassess the type of extruder currently in use.
Twin-screw extruders come in various types depending on the screw\u2019s \u201crotation direction\u201d<\/span> and \u201cengagement method.\u201d<\/span>
Among them, the \u201ccounter-rotating, non-intermeshing type\u201doffers excellent compounding performance and stable, high-throughput volume\n\u2014while maintaining operability comparable<\/span>to conventional systems.
Here\u2019s why counter-rotating, non-intermeshing twin-screw extruders significantly boost productivity<\/div>\n
*Based on comparison of throughput between non-intermeshing, counter-rotating and intermeshing, co-rotating twin-screw extruders (screw diameter: 40 mm, data provided by CTE).<\/div>\n

Easier gas venting<\/span>enables greater
raw material input<\/span><\/h3>\n<\/p><\/div>\n

In an intermeshing, co-rotating extruder, air and gas are blocked at the kneading disc section,causing a feed-neck phenomenon\u2014a condition where gases generated during melt blending flow back into the feed zone.<\/span>As a result, material cannot be fed smoothly.<\/p>\n

In contrast, a non-intermeshing extruder does not use kneading discs, but instead kneads material between the rotating rotor and the cylinder wall. This structure allows air pathways to form,enabling gases to vent smoothly through the exhaust port.<\/span>This suppresses backflow, prevents clogging, and ensures stable feeding of high material volumes.<\/p>\n<\/p><\/div>\n

Lower heat generation during kneading eliminates<\/span>the need to lower
screw speed.<\/span><\/h3>\n<\/p><\/div>\n

In an intermeshing extruder, material is forced into the narrow kneading disc section, where high shear force is applied.This generates frictional heat, causing the resin temperature to rise rapidly.<\/span>To avoid thermal degradation, the screw speed must be reduced, which in turn lowers the throughput volume.<\/p>\n

In contrast, a non-intermeshing extruder uses a rotor instead of kneading discs to process the material.This grinding-like process reduces localized shear and significantly lowers heat generation.<\/span>As a result, there is no need to reduce screw speed due to heat concerns, enabling continuous high-speed operation.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n
