Nordson EFD's MicroMark precision spray marking systems produce neat, consistent spots and stripes from 3.3 to 30mm without overspray or clogging. The company claims that the spray marking systems dramatically reduce downtime on automated and semi-automated production lines.
Based on the company's low volume low pressure precision spray technology, the marking systems' valves provide controlled application for an array of marking materials. The system's high transfer efficiency and swift cutoff enhances part appearance. A short microburst of air after each shot secures the nozzle from clogging and reduces maintenance.
The 787MS valve spray nozzle enables 3.3 to 5mm sprays, whereas the 781S-SS valve allows round or oval shaped covers from 5 to 30mm. The marking system includes a microprocessor-based controller that simplifies system setup and operation. The controller can be interfaced with a programmable logic controller if desired. Ink or paint is supplied from a fluid reservoir with a constant-bleed air regulator that prevents fluctuations in fluid pressure. The marking system is suitable for colour-coding applications that differentiate between similar components.
