6 Considerations For Selecting The Right UV Dispensing Equipment

With the advancement in technology, various dispensing techniques are available in the market. With each technique, UV dispensing equipments are there. Dispensing is done in many applications, such as:

• Electronics
• Automotive
• Medical
• Pharmaceutical
• Watchmaking

If you are not familiar with the dispensing technology, it will be difficult for you to select the right dispensing machine. The following aspects will help you in selecting the right dispensing equipment for your applications.

Manual Syringe System:

A manual dispense procedure is the most basic approach to dispense fluid. A plunger with a piston and a syringe filled with fluid are typical components of a manual system. The operator just pulls the plunger down until the workpiece receives enough fluid. The consistency with which the operator can repeat the process. This determines the rate of repeatability. This is also appropriate for low-volume applications.

Time and Pressure Dispensing (TPD):

The next thing to consider is the time and pressure dispensing (TDP) technique. As it is clear from the name that this technique uses air pressure with a control timing circuit. This increases yields and product throughput. With its simple repeatability rate and decency, almost 60% of the dispensing applications are done by this technique.

Time and Pressure Syringe System:

The basic time and pressure dispensing syringe system start with:

• Dispenser
• Airpower syringe
• Receiver head assembly

The syringe filled with fluid that is to be dispensed is connected to the time and pressure dispenser through the receiver’s head assembly. After this, the right air pressure and dispense time are set accordingly on the dispenser. After this setup is done, the operators can activate the dispense cycle. This is done by pressing the footswitch or the finger switch.

During the operation, the dispenser delivers a measured amount of air pressure for a present dispense time to a syringe. With the dispensing needle, the controlled shot of air forces the fluid out of the syringe onto the work surface.

Pinch Tube Valve:

A simple and reasonable TPD valve is the pinch tube valve. It is disposable and designed to dispense small dots or continuous beads. This valve is operated by automatically opening and closing a molded plastic tube assembly. Its benefits are:

• Disposable path
• Lightweight
• A simple operation
• Compact size

Diaphragm Valve:

Some of the applications require frequent pinch tube replacement. For this, the diaphragm valve is the best. The advantages of this valve include:

• Compact size
• Lightweight
• Simple and low-maintenance
• Adjustable stroke control

Needle Valve:

For the applications that require microdot size, a needle valve is an ideal choice. Sizes as small as 0.0005 CC are easily achieved. Advantages of this valve include:

• Dispense a small amount of UV adhesive
• For marking, it dispenses a small dot of ink.
