Screw combines the simplicity and economy of a conventional three-zone screw
The Xaloy EasyMelt? injection molding screw is a multi-purpose screw combining the simplicity and economy of a conventional three-zone screw with the productivity and quality benefits of optimum material feeding, melting and metering zones.
Benefits
Faster screw recovery
Reduced short shots
Improved temperature control
Features
Optimum resin-tailored feed depth
Optimum zone length
Optimum metering depth
Applications
Highly glass-filled materials
Materials with metallic powders or mica fillers
Shear-sensitive polymers
Undemanding processes
On-the-money metering
Insufficient depth in the metering zone for a given material can reduce
plasticating rates by 28% or more, but for some resins, too deep of a
metering depth will not apply the proper amount of shear on the resin
to allow for a uniform melt to be delivered to the mold. That?s why a
metering depth that?s just right really pays off.
Efficient melting
Thanks to its resin-tailored feed depth, compression ratio and zone
lengths, the Xaloy? EasyMelt? screw delivers fully melted material to the
metering zone. This avoids a major cause of intermittent short shots:
partially filled flights and pressure instability in the metering zone.
