In most times, taking a close look at some of the smallest dynamics in the assembly process can bear significant returns in relation to the manufacturing process. In other scenarios, small details such as checking to ensure the operators use the appropriate dispensing tips are required to ensure the fluid is properly dispensed.
Each part of the fluid ranging from the thick grease to thin solvents to pourable adhesive bear different properties that need to be considered. A clue concerning these properties goes a long way in ensuring that the right type of dispensing tips us used for a specific application.
Many people inquire about the basics of the different types of dispensing nozzles. The main reason is that there are different types of fluids that bear different properties for various application requirements. When using the inappropriate dispensing tip, it increases the chances of reworking and rejecting the cycle rates. This leads to poor quality of the production process.
There is a number of videos available to help you understand the basics of the different styles which are available. This will guide you in how to select the proper tip for your fluid type for improved process control.
Dispensing Most Fluids? What To Do
The most used dispensing needle is the general-purpose tip. This forms part of the workhorse group because of its ability to dispense different types of assembly fluid. However, due its ability to dispense different types of fluid, it does not mean that it is the appropriate choice for your situation.
Dispensing Thin Fluids or Low Viscosity
The choke point from a general-purpose tip is best suited due to its small diameter which gives control overflow of thin fluids. When it comes to dispensing solvents, it is better preferred to select a coated dispense tip due to its special outer coating.
The coating goes a long way in preventing fluids from wicking up the outer part of the cannula. This helps in improving the depositing accuracy. In terms of instant adhesives, you will require a specific lined tip because of the fast curing consistency of the fluid.
Dispensing Medium to High Viscosity Fluids
For thick viscosity fluids, a common recommendation is with the tapered tips due to its ability to promote flow. It also helps in dispensing with precision and continued consistency of fluid deposits in the shortest amount of time.
Tapered tips are essential in ensuring that you lower the pressure placed on the pneumatic fluid dispenser. However, you can still lower the pressure with the use of a general purpose tip while using a smooth flow tapered tip. It is also important when dispensing the filling material to ensure there is high pressure due to the filled materials separate in the syringe barrel.
When using a tapered tip for dispensing thick fluids, it helps the user to apply faster the deposits compared to using a general-purpose tip. This is important in ensuring that it yields an increase in productivity when dispensing.
