The Xaloy Quantum™ plasticizing screw is an ultra-high performance barrier screw, targeted to recovery limited, thin wall processes utilizing polyolefin resins. The innovative barrier screw design of the Xaloy Quantum™ plasticizing system ensures a mass balance throughout the screw that compensates for the conversion between feedstock bulk density and resin melt density, thereby controlling shear rates and shear stresses throughout the melting process.
Features
- Mass balance design, controlling shear stress
- Improved screw recovery time by 10 to 15% dependent upon process parameters
- Innovative barrier design achieving homogeneous melt quality at high process speeds
Applications
- Recovery limited injection molding processes utilizing polyolefin resins.
- Example: High volume, high speed production of thin-wall packaging
- Optimum plasticizing rate and recovery times
- Increased plasticizing rate of unmelted material
- Maximized melting efficiency through controlled shear forces of the polymer
- Valve prevents polymer degradation and ensures excellent shot-to-shot repeatability
- Optimized melt quality in high speed applications
- Decreased percentage of scrap produced
- Yields a rapid return on investment
