The Easy-Melt™ screw from Nordson Xaloy combines the simplicity and economy of a conventional three zone screw with the productivity and quality benefits of optimum material feeding, melting and metering. The Easy-Melt screw is a significant improvement over the ‘General Purpose’ screw and can be customized for your specific resin .

Efficient melting

With the correct and resin specific feed depth, compression ratio and zone lengths, the Easy-Melt™ 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.

Precise metering

Insufficient depth in the metering zone for a given resin can reduce plasticizing rates by 28% or more, but for some resins an excessive metering depth will not deliver the correct shear to the resin. Designing the correct metering depth allows a uniform melt to be delivered to the mould

What it can do for you

  • Speed up screw recovery
  • Reduce short shots
  • Improve temperature control

Typical applications

  • Highly glass-filled materials
  • Materials with metallic powders or mica fillers
  • Shear-sensitive polymers
