Extruder Screw Designs
The Extruder Screw is the heart of the Extruder and it is very important to specify the correct design and construction materials.
​
Many extruders are supplied with 'General Purpose' designs and many others are supplied with designs that are far from optimized.
​
In contrast, Cooper Technology supply a range of high performance screws designed to improve your process and boost your productivity. A number of patented Xaloy screw designs are available, and these can be modified to suit your particular process and resins.
​
The overall aim is to provide the best possible melt quality, with improved mixing and homogeneity, while also increasing output and ensuring the best possible productivity.
​
Improved mixing often leads to reduced masterbatch requirement, and subsequent cost savings.
Barrier Screws
The patented Xaloy® Fusion™ screw allows you to increase production and improve product quality in injection molding and extrusion process applications. Its design is the combination of proven barrier screw technology and a low shear metering section that provides chaotic mixing, reduced melt temperatures and improved throughputs.
Alloys & Coatings
It is important to choose the correct construction materials and coatings in order to maximize wear life and enhance process stability.
The majority of screws are still manufactured from nitriding steels but at Cooper Technology we offer a broad range of special alloys.
