Dispense tips or needles play an important role in precision fluid dispensing systems. When selecting these devices, it is vital to put several factors into consideration. It is not enough to select the tip that works. You should choose the one that is most suitable for your application. Precision dispensing tips come in a variety of lengths, gauges, angles and threads among other features which enhance accuracy and dispensing reliability for different fluid types and applications.
You can select from a wide range of dispense tips on the market. These include blunt, tapered, PTFE-lined, and angled blunt end tips. The tips are made with a variety of materials like polypropylene, Teflon and stainless steel. When you select the proper dispense tip, the fluid dispense process will be smooth. You should contemplate on the kind of fluid you want to dispense to select the right type of needle.
It is critical for the shape, length and gauge of the dispense tip to meet the exact dispensing needs of your project to ensure that the fluid will be deposited precisely and the overall dispense system will work optimally. The reason many kinds of dispense tips exist is that many kinds of fluids with different properties are available to meet various application requirements. If you use the wrong dispense tip, your rejects, reworks and cycle rates will increase, leading to an inefficient production process and poor part quality.
The general purpose tip is the most common dispense tip available. It is versatile meaning that you can use it to dispense many different types of assembly fluid. Nonetheless, the ability of the general purpose dispense tip to dispense many different types of fluids, it may not be the suitable tip for your application. You should select the tips that can dispense the correct amount of fluid as quickly as possible.
When dispensing low or thin viscosity fluids, it is advisable to use a general purpose tip with a small diameter. The choke point of such a dispense tip will limit the movement of thin fluids to ensure better control of the dispensing process. Nevertheless, if you want to dispense solvents, it would be recommendable to choose a dispense needle that is PTFE coated. The outer coating will prevent the fluid from wicking up on the cannula. This will ensure that the deposits are accurate and enhance repeatability.
When you want to dispense thicker viscosity fluids, tapered tips are ideal. The tapered dispose needles enhance flow and this will enable you to dispense a large number of accurate and consistent fluid deposits within a short time frame. When using tapered dispense needles, you can reduce the pressure on a pneumatic fluid dispenser.
Dispense needles differ in quality even if they may appear to be the same. Therefore, it is vital to buy them from a company that has a stringent quality control process. Poor quality dispense tips may have burrs or molding flash, which can transform the quality of fluid deposits or contaminate the material.
The other factor to put into consideration is if the dispensing components like the syringe barrel, dispense tip and adapter assembly can work together in a seamless manner. They should deliver accurate and consistent liquid deposits with minimal fluid wastage. This will enable you to save money over time.
