It can be challenging to choose tapered dispensing tips because many different types are available. However, it’s important to pick the right products to ensure proper dispensing of fluid, glue, resin, or sealant. Dispensing tips may seem like minor aspects of the assembly or manufacturing process, but their quality and type can make a difference in improving your lead times and throughput. That’s because every assembly fluid from thick grease to thin solvents and pourable adhesives have unique properties that should be considered. By knowing their unique properties, you can pick the best type of dispensing tip for every application.
Why do you need the right tip?
There are many types of tapered dispensing tips to suit different fluids with various properties for various application requirements. For example, the dispensing needle can adjust the mixing nozzle’s flow, and it can be matched with a rubber cylinder to fulfill precise linear and dot gluing work. However, the wrong choice of tip could result in inefficient production and poor part quality, which can increase cycle rates, the need for rework, and rejects. So, here are some tips to help you pick the ideal tapered dispensing tip for the most common applications:
Check The Features
The tapered needle design should suit most liquids, including sealants, resins, gels, and epoxy adhesives. The exit should ensure precise application without burrs to ensure that the glue is consistent and accurate. Make sure the tips are certified for industrial use.
Refer To The Fluid
Tapered tips are usually best for fluids with thicker viscosity as they promote flow to ensure consistency and precision when dispensing the fluid deposits quickly. The tapered tips should let you lower the pressure on the pneumatic fluid dispenser. Consider tips with UV-blocking agents to prevent any UV-cure materials from curing within the nozzle.
Explore The Options
Tapered dispensing tips come in different sizes, differentiated by their physical features (i.e., the color) and gauge. For example, manufacturers of dispensing tips offer them in gauges 14, 16, 18, 20, 22, 25, 27, and 30, in 31.6mm long and different IDs (in mm), such as 1.55 (14 gauge), 0.84 (18 gauge), and 0.3 (25 gauge).
