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 commonest dispense needle is the general purpose needle. This dispense tip is versatile. It can dispense almost all kinds of assembly fluid. However, even though this needle can dispense nearly all kinds of fluids, this does not mean that it is the most appropriate choice for your fluid. You should choose a tip that can dispense the right amount of fluid within the shortest time 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.
Tapered needles are suitable for dispensing fluid with thicker viscosity. These tips improve the flow of liquid and this can allow you to dispense a lot of fluid deposits concisely, accurately, consistently and quickly. As you utilize a tapered dispense needle, you can also lower the pressure on pneumatic fluid dispensers.
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.
Another essential factor to consider is the dispensing components, including the dispense tip, piston, adapter assembly and syringe barrel are designed to work together properly. The components should deliver consistent and accurate fluid deposits with minimal waste of fluid. This will help you save money over the years.
