Reduce waste in sealant and adhesive applications

| By Chemical Engineering



The Hydraulic Fixed Ratio (HFR) Metering System (photo, p. 29) improves throughput and significantly reduces waste and rework in adhesive and sealant dispense applications. The HFR is a meter, mix and dispense system that is capable of processing multiple sealant and adhesive materials. As the system dispenses material, it automatically fine-tunes and adjusts material flows and pressures to achieve a consistent bead. The system features intuitive controls that allow users to program up to 100 different shot sizes and easily configure temperature control. In addition, the system gives users immediate access to data about material usage, pump cycles and errors. The system is capable of producing either a constant-pressure material output or a constant-flowrate material output. — Graco Inc., Minneapolis, Minn.
