Producing melt at rates that can reduce cycle times in injection molding of high-speed, thin-wall packaging, Xaloy Quantum™ helps molders increase throughput while maintaining part quality and consistency. Included barrier screw increases rate of plastication for unmelted material while minimizing shear forces on polymer already in molten state. Custom-designed poppet-style, non-return valve offers free-flowing channels that prevent polymer degradation and accelerated shut-off.
