Manual fluid dispensing can be tricky to a beginner, but there are some simple rules and guides that can help. Read on to learn Fisnar Europe’s top tips for fluid dispensing!
Cyanoacrylates: Handle carefully. Avoid all skin contact. Adjust the vacuum with extreme caution and do not allow the cyanoacrylate to run back through the airline to the dispenser. Always use a safety clip on the adapter hose when changing the tip to prevent dripping and material being sucked into the controller.
Anaerobics: The same precautions should be enforced as with cyanoacrylate.
Epoxies: Using normal methods, one-part epoxies can be dispensed without problems.When dispensing two-part epoxies, always remember that in the epoxy curing process the viscosity will change with time, thus affecting the dot size. The controls of the dispenser will need to be adjusted to compensate for the viscosity increase as the material ages.
Solder and brazing pastes: Precise control is achieved with dispensing. For precise micro shots of solder pastes, the positive displacement screw valve is recommended. Care must be taken when transferring or loading paste into barrels to avoid air entrapment.
Silicones, masks & solder resists: Use normal dispensing procedures.
Adhesives: All adhesives dispense well. By using a small tip, “stringing” may be eliminated.
Lubricants: All lubricants dispense well.
