How To Select Suitable Precision Dispensing Tips
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.
There is a wide selection of dispense needles on the market, including PTFE-lined, brush, angled blunt end, blunt and tapered dispense needles. These needles are made of a wide range of materials, including Teflon, stainless steel and polypropylene. As you dispense fluids, it is essential to choose the right dispense needles for the syringe. The type of needle you need depends on the kind of fluid you are dispensing.
You should make sure that the length, gauge and shape of a dispense needle meet the precise needs of your application. This way, the needle will deposit the fluid accurately and the entire dispense system will work in an optimal manner. Different types of dispense needles are available because many fluids have different properties to meet unique application requirements. Using the wrong dispense needle will increase your cycle rates, rejects and reworks, causing poor quality of parts and an inefficient production process.
The dispense needle that is most common is the general purpose needle. The main benefit of this dispense needle is versatility. You can use it to dispense most kinds of assembly liquids. Even though this dispense needle can dispense almost all kinds of liquids, it may not be the best kind of tip for your application. You ought to select a needle that will dispense the correct amount of liquid fast.
When you want to dispense thin or low viscosity fluids, it is better to use a general purpose tip that has a smaller diameter. The choke point of such a dispose tip will restrict the flow of thin fluids ensuring better process control. However, when you need to dispense solvents, it is better to select a PTFE coated dispense needle due to the special outer coating that keeps the fluid from wicking up outside the cannula. This will enhance deposit accuracy and 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.
The dispense tips from different companies may look alike, but they are different in terms of quality. It is advisable to buy the tips from a company whose quality control process is stringent. High quality dispense needles are devoid of burrs or molding flash that can pollute the material or change the quality of your liquid deposits.
You should confirm that the dispensing components such as the dispense needles, adapter assembly, syringe barrel and piston are designed to work together well. These components should offer precise and consistent fluid deposits without wasting a lot of fluid. This will translate to savings over the years.
