Syringe dispensing systems deliver accurate and consistent fluid deposits, they are simple to set up and operate, and can be used to dispense a wide  variety of low to high viscosity fluids. 

The rudimentary way to dispense fluid is through a manual dispensing process. A typical manual system includes a plunger with piston and a syringe filled with fluid. The operator just simply pushes the plunger down until enough fluid is dispensed on the substrate. Repeat-ability rate depends entirely on how consistent the operator can repeat the process. This method is suitable for low volume applications where product yields below 80% are acceptable. 

When to Use Syringe Dispensing Systems

Syringe dispensing systems offer a low cost and simple way to dispense a wide range of fluid and adhesive materials. Shop our complete syringe dispensing systems and customize to meet your application needs. Great for dispensing single component materials like cyanoacrylates, primers, epoxies, greases, inks and much more.

Time-Pressure Dispensing

Time pressure dispensing is the most common dispensing method used today. It's popularity stems from the need for process control and the fact that it is possible to dispense from disposable containers without the need for cleaning. 

Our time-pressure dispensers deliver a measured amount of air pressure, for a measured amount of time, to a pre-filled syringe barrel. This controlled shot of air pressure forces material out of the delivery end of the barrel, through a dispensing tip, and out to the application surface. 

Factors Affecting Dispensing

  • Pressure: Increasing fluid pressure will increase dot size and vice cersa
  • Time: Increasing dispense time will increase dot size and vice cersa
  • Dispensing Tip Size: Larger inside diameter (orifice) needle results in bigger dot size

Guidelines for Syringe Dispensing

  1. Small Shot Size = small dispensing tip, low fluid pressure, short dispense time
  2. Large Shot Size = larger dispensing tip, higher fluid pressure, longer dispense time
  3. Low Viscosity Fluid = larger dispensing tip (tapered dispensing tip recommended), high pressure, time as required
  4. Position syringe barrel at 45 degree angle
  5. Position the dispensing tip close to the work surface then activate the dispense cycle and keep the syringe barrel in the same position until the cycle is completed
  6. If vacuum "suck-back" is needed, use only enough vacuum to draw back fluid into the dispense tip. Excessive vacuum could draw air into the fluid and also could draw fluid into the dispenser.

Versatility With Cost Advantages

Whether powered manually or pneumatically, simple time/pressure dispensers offer a versatile, low cost solution to dispensing applications. From their modest beginnings, syringe barrels have since evolved into precision engineered products designed to offer the accuracy, repeat-ability and stability required in electronics manufacturing. 

To give you an example, silicone and chloride free, low friction polypropylene syringe barrel bodies are available in amber to protect the latest UV sensitive liquids (up to 520 mm) while letting the operator view the volume of material in the syringe barrel. Similarly, different designs of air powered pistons have been developed to ensure an even pressure spread. Polyethylene wiper pistons are optimized for low to medium viscosity fluids, while straight wall pistons are recommended for reducing stringing with medium/high viscosity fluids.

For pneumatically powered applications, a quick and clean connection between the syringe barrel and time/pressure dispenser 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.
