Nordson EFD has launched the PICO Pµlse XP HV jetting system for non-contact precision dispensing of high-viscosity materials in assembly applications. The system is designed for materials including thick silicones, greases and UV-cure adhesives, and applications such as optical bonding adhesives and precise one drop fill.
New formulations are entering the industrial marketplace through product development in electronics, medical and automotive industries, according to Nordson EFD. The company adapted its piezoelectric jetting system for non-contact dispensing of these viscous materials.
The valve applies deposits as small as 1 nanoliter at speeds up to 600Hz (deposits per second) with proper valve cooling, and up to 1000Hz bursts. It upgrades the existing XP valve with higher jetting power and the ability to dispense higher-viscosity materials. Its expanded dispensing parameter range and specialized piezo actuator are designed for long service life and reliable operation in production environments.
Key features include a tool-free latch for fluid and material changeouts in seconds; self-regulating calibration; continuous stroke target seeking to improve valve-to-valve repeatability; and reduced variability by up to 80%, according to Nordson EFD. The valve is compatible with the PICO Nexµs controller for plug-and-play integration within a connected Smart Factory.
Claude Bergeron, Nordson EFD product line manager, said the system enables engineers and machine integrators to jet dispense new viscous materials with confidence. He said Nordson's fluid process experts use the technology in validation laboratories worldwide to identify dispensing configurations for assembly applications.
