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.
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 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 planning to dispense the fluids with a low viscosity, you can utilize a general purpose needle with a smaller diameter. Its choke point will limit the flow of thin fluids to ensure better process control. When dispensing solvents, it is advisable to choose a PTFE coated dispense tip. With such a needle, the fluid will not wick up on the exterior of the cannula because of the special exterior coating of the tip. This can improve repeatability and the accuracy of deposits.
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.
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.
