Posi-Melt™ Screw - the Ultimate Multi-Purpose Screw
The patented Posi-Melt™ screw is designed as a Multi-Purpose screw, enabling you still to process a range of resins, but with reduced screw back time, improved mixing and greater process consistency.
​
For applications where only one resin is processed, we can supply custom designed screws, often based on Posi-Melt™ technology. These give even greater process improvement than can be achieved with the 'standard' Posi-Melt™ screw.
-
Patented design offers higher melt quality and throughput than GP screw.
-
Change in pitch generates a mixing effect without the need for a mixing section.
-
Suitable for a wide range of resins – a true Multi-Purpose Screw.
-
Competitive manufacturing cost ensures the Posi-Melt™ is a cost effective choice.
-
Large range of alloys and coatings available for every application.
-
Available to suit any machine type or size.
Essential differences between a 'GP' screw and the Posi-Melt™ Screw
Through a series of flight pitch and root changes, the Posi-Melt™ screw delivers a more thoroughly melted and mixed melt pool.
Improved Processing Window
The improved melt quality of the Posi-Melt™ screw enables you to mould parts that are difficult to mould with a general purpose screw and the process window is substantially increased, as depicted in the graph. Also, one design is able to work extremely well with all resin groups.
