Grease, silicone, RTV, potting compound, anti-splatter fluid, rust inhibitor, marking fluids, hot glue. All of these materials have at least one thing in common: theyre dispensed on a daily basis in numerous industries across the US, oftentimes with wildly varying degrees of success. Our company works with these fluids regularly, for a wide variety of clients. In the last six years, weve leaned a lot about dispensing systems and how to apply them to meet the needs of our customers. Here are a few key elements to consider when facing your next dispensing application.
-> High Pressure or Low?
-> Time-Pressure vs. Positive Displacement
-> Closing the Loop with Flow Meters
High Pressure or Low?
The viscosity (usually measured in centipoises) of our media will determine the pressure that it takes to move it. For example, dispensing dots of Cyanoacrylate, (Super Glue) might require no more then 5-10 PSI, while flange sealant (RTV) might require 2000 PSI or more. The exact pressure required doesnt really matter, as components are available to cover most applications. The important thing is not to mix and match high and low pressure components....
