Bench-top fluid dispensing: Easy when you know how


Manual handheld, semi-automatic and automatic represent the three dispensing methods for adhesive dispensers. These methods can used in many industries such as Electronics assembly, Medical device manufacturing or Aerospace. The success of the adhesive dispensers relies heavily on making the right choice of equipment and consumables to suit each application. 

Versatility with cost advantages - Syringes

Whether powered manually or pneumatically, simple time/pressure adhesive dispensers offer a versatile, low cost solution to adhesive dispensing. From their modest beginnings as adhesive dispensers, syringe barrels have evolved into precision engineered products designed to offer the accuracy, repeatability and stability required during manufacturing.

For pneumatically powered applications, a quick and clean connection between the syringe barrel and time/pressure adhesive dispensers is possible due to the development of receiver head assemblies that comprise a syringe barrel receiver head, O-ring seal, pneumatic tubing and quick-connector. Similarly, for manual syringe barrel dispensing, simple, lightweight barrel applicator guns are also available which can provide excellent, drip-free control for medium/high viscosity products.

Rising to any challenge - Valves

For more demanding applications, valve-based adhesive dispensers can range from simple pinch tube adhesive dispensers to encoder controlled rotary feed screws (augers).

Pinch Tube Dispense Pen and Valve adhesive dispensers offer a simple introduction to valve-based adhesive dispensers. Pinch tube adhesive dispensers  feature a mechanism which releases a pinched tube when the operator presses the actuator. Capable of controlled shot size and flow rate, gravity or pressure fed, these valves can be used to dispense fluids ranging from 1 to 45kcps viscosity, such as cyanoacrylates, anaerobics and two-part adhesives.

Diaphragm valves incorporate in adhesive dispensers are designed without seals for moisture sensitive fluids to accurately dispense low to medium viscosity materials (1 to 50kcps) over a wide range of shot and bead sizes. Adhesives typically dispensed with adhesive dispensers via diaphragm valves include cyanoacrylates, anaerobics and, UV-cure adhesives.
