Description

Preci-Tip™ Precision Dispensing Tips or Nozzles are designed for accurate dispensing of dots, beads or in-fills. Their streamline conical fluid path delivers considerably higher fluid flow rates and lower dispense pump back pressures than most standard dispensing tips. This results in improved dispensing accuracy and component life. The thin wall nozzle cores are produced using a deep drawing process, giving particularly low resistance to fluid flow, and exceptional accuracy and robustness compared to plastic dispensing tips or nozzles.

They have an industry standard Luer Lock thread and can be used with common dispensing barrels or valves.

Preci-Tip Precision Dispensing Tips feature walls which are very thin and rigid, resulting in a smaller outer diameter (OD) required for large inner diameter (ID) fluid paths. This can be particularly useful where a small gauge tip is needed, without compromising on fluid dispense rates. The thin walls further enhance the accuracy and definition of dots, lines or special patterns, and dramatically reduce fluid stringing or tailing tendencies.

Preci-Tip Precision Dispensing Tips standard gauge tips are made from phosphor bronze with electroless nickel coating. This provides a hard, abrasion resistant nozzle with low resistance to fluid flow. As an option, Preci-Tips are available with a nickel PTFE coating – an electroless nickel coating with polytetrafluoroethylene particles. This provides a hard, abrasion resistant, inert, lubricious and hydrophobic surface which provides even better release of liquids and oils. Micro-gauge Preci-Tips are made from nickel silver. All Preci-Tips have polypropylene hubs.

Features & Benefits

  • Dispense dots and beads as small as 50 microns
  • High accuracy, repeatable dispensing
  • Reduces dispense pump back pressure, improving performance
  • Tips are clog-resistant and tapered for ease of flow, with good fluid break-off
  • Resist stringing
  • Rigid metal nozzles have a much longer lifespan than single-use plastic dispensing tips
  • Precise exit apertures
  • Industry standard Luer Lock fitting compatible with any of our dispensing valves, pumps, or barrels

Applications

  • Dispensing of adhesives, UV cured adhesives, filled adhesives (thermally or electrically conductive), solder paste
  • Automated dispensing applications with tight tolerances and micro quantities
  • Semiconductor packaging, encapsulation, underfills
  • Applications and processes requiring repeatability and accuracy for validation, such as medical device assembly
  • Placement of viscous, small diameter dots and lines
  • Deposit of high surface tension fluid into wells
  • Silicone gasket applications
  • Dropping of phosphor laden silicone onto LEDs
  • Dispense of grease/thermal grease
