The dispensing tip, also known as a dispense needle is a critical part of precision fluid dispensing systems. Therefore, when choosing such a tip, you should consider several factors. You do not want to choose just the tip that works, but rather one that is suited best for your application. Precision dispensing tips have varying gauges, lengths, threads and angles among other features meant to optimize dispensing repeatability and accuracy for each application and fluid type.
Many different kinds of dispense tips are available on the market. They include brush, blunt, PTFE-lined, tapered and angled blunt end dispense tips. Some of the materials used to make these products include stainless steel, Teflon and polypropylene. To dispense fluids properly, it is critical to select the appropriate dispense needle. Consider the kind of fluid you need to dispense in order to choose the right needle.
It is vital for the gauge, length and shape of a dispense tip to meet the needs of your application. This way, the liquid will be accurately deposited and the whole dispense system will work optimally. One of the reasons why several types of dispense needles exist is due to availability of fluids with unique properties. The needles are designed to meet different application needs. If you were to use an incorrect needle, your cycle rates, rejects and reworks would increase, leading to poor part quality and a wasteful 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.
Even though the dispose tips of one company may appear identical to those of another company, they are not the same. Therefore, ensure that the company you choose to buy dispense tips from adheres to a strict quality inspection process. The best dispense needles do not have molding flash or burrs that can contaminate your material or change the consistency of your fluid 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.
