ASSEMBLY ESSENTIALS
For users looking to achieve super accurate dispensing as well as higher throughput and profitability, then high-speed piezo jet valve dispensing could be an extremely worthwhile investment.
In many high-volume production environments where adhesives and fluids are used, there is a continuous drive for faster dispense rates, higher throughput, and profitability.
High-speed jet valve dispensing is an innovative technology that can dramatically increase dispensing rates of adhesives and other fluids. A noncontact dispensing method, high-speed jetting is the process of material being shot from a fixed location onto the desired substrate with outstanding consistency and repeatability. As the jet valve never comes into contact with the surface, there is a much higher degree of dispensing flexibility, meaning it can be used in a wider variety of applications. Piezoelectric jet valves can dispense at approximately twice the speed of standard, pneumatic jet valves. Despite moving at such high rates, users of piezo jet valves are often amazed at how precisely and accurately they can dispense small, neat dots or lines.
Additionally, jet valves gain a significant speed enhancement over pneumatic valves as they eliminate the Z-axis of movement. The high-speed jet dispensing is contactless and shoots the material repeatedly at a fixed location above the substrate. As users do not have to monitor and reposition this axis after each dispense application, they can save valuable production time and therefore achieve much higher dispense and turnover rates.
High-speed jetting does not rely on actual contact with the substrate as the material is shot rather than physically placed, which allows for several key advantages over traditional, contact-based dispensing methods:
Easy to dispense in hard-to-reach or uneven areas
Prevents possible surface damage or wasted materials
Fast dispensing with advanced process control
Extremely accurate product placement (as small as 0.5 nl)
Dispense pattern flexibility
Reduced setup costs
Clean needle tip material cut off
Systems which incorporate modular jet valves are the perfect solution for this as they can be configured for both contact and non-contact jet dispensing. By opting for a modular jet valve, users can dispense a wider variety of fluids and fluid viscosities. This includes materials such as underfill epoxies, encapsulants, and conformal coatings.
Other benefits of modular jet valves include:
Improved turnover times
Easy optimization or reconfiguration
Fast maintenance and individual parts removal
Quick, consistent dispensing of beads or lines
