Fluid Dispensing Q&A

  •   My company has a new project that requires dispensing a thick medical-grade silicone through a small needle. We tried hand syringes, but the process was extremely difficult for workers to perform and took too long. Hand fatigue was a problem, and we were concerned about the possibility of long-term injuries. We hoped an air-powered dispenser with 100 psi of output would be the answer, but while it resolved the hand fatigue issue, it is still too slow to be considered a permanent solution.

    So many companies asked for help with this problem that we developed the HP High-Pressure Dispensing Tools, which make it easy to apply RTV silicones, epoxies, medical-grade adhesives and other thick fluids through dispense tips as small as 0.004 in. diam.

    These tools are designed to work with EFD precision fluid dispensers, and can multiply the output of a standard 100-psi dispenser up to 7X to produce a maximum dispensing pressure of 700 psi. This provides fast, fatigue-free application of thick assembly fluids, minimises the risk of repetitive stress injuries and increases yields by enabling workers to easily apply the correct amount of material in much less time.
