Nordson Corporation has developed an online tool that quickly calculates the resin cost savings achievable with installation of a BKG® BlueFlow™ gear pump, plus the number of months in which the investment in the pump is paid back in full. The company will introduce the tool at Chinaplas 2019 (Booth 2.1F41).
Installed between the extruder and the die, a gear pump shifts the job of building melt pressure from the extruder to the gear pump. Besides reducing stress on the extruder and potentially increasing throughput, the gear pump significantly reduces the effect of process variations on melt pressure. This enables extrusion processors to run with narrower tolerances without compromising product uniformity.
