In 2025, new quality productivity, as an intrinsic requirement and key focus for driving high-quality development, is profoundly impacting various industries, including electronics manufacturing. In this context, high-precision dispensing equipment plays an increasingly significant role in electronic component production: it enables precise control of glue volume, stable dispensing, ensures the quality of electronic components, thereby enhancing overall product performance and meeting production demands.
MEST's independently developed Piezoelectric Jet Valve MEST-F910, as a hot-selling product in the glue valve series, brings customers a brand-new user experience with its advantages in high precision, high efficiency, high consistency, and high flexibility.
Stable operating frequency of 500Hz Instantaneous maximum frequency up to 1000Hz Micro-dispensing with precise glue volume control Minimum jet volume of 5nL Achieves minimum line width of 0.15mm.
High-speed air-jet dispensing enables high-speed dispensing on smooth/uneven/flexible substrate surfaces Less prone to defects like scattered dots or irregular glue spots Maintains high stable needle impact force during operation Quick-disassembly flow channel structure for easy maintenance.
The Piezoelectric Jet Valve MEST-F910 features high jetting pressure, suitable for fluids with viscosities from 0 to 200,000 cps, making it the optimal choice for jetting low, medium, and high-viscosity adhesives. It also offers a wide heating range, with temperatures up to 150°C. So, what exactly is its working principle?

First, the needle and nozzle are pressed tightly to seal, while the adhesive fills the entire cavity under pressure. Then, when the voltage applied to the piezoelectric stack changes, the piezoelectric stack deforms, and the swing arm moves due to spring preload, creating a gap between the originally tightly pressed needle and nozzle. At the same time, the adhesive, under pressure, fills the gap created by the needle's movement.
Next, when the voltage on the piezoelectric stack changes again, the piezoelectric stack deforms once more, and the swing arm quickly presses the needle, causing it to return rapidly. During this return, the needle forcefully ejects the glue in the gap through the nozzle, completing one jetting action, and restores the nozzle's sealed state, preparing for the next jet.
This continuous process, through precise voltage control, generates kinetic energy inside the valve, allowing the fluid to be jetted with precisely controlled pressure, achieving accurate piezoelectric dispensing operations. Since the piezoelectric jet valve eliminates Z-axis movement, it reduces repositioning and up-down motion time, delivering significant high-speed effects.
