Sealant Equipment & Engineering Inc. (Plymouth, Mich.) has developed the Servo-Flo 704-HV, a two-component, variable-ratio, high-volume, meter/mix/dispense system for automated, semiautomated or robotic dispensing applications. Designed to dispense variously sized mixed-material volumes, the dual-servomotor device accepts low- to high-viscosity materials and electronically adjusts the material ratio without changing meter hardware. Its continuous-flow, dual-gear meter system mixes and dispenses two-part epoxies, polyurethanes, silicones and acrylics. It provides fixed and variable flow-rate dispensing or variable flow-rate profiling.
