High jetting force Dual dispensing Piezo Jetting valve for precision electronics application

Dual-piezo jet valves are highly effective for dispensing hot melt adhesives(HMA) in advanced manufacturing applications. With two piezoelectric actuators working in tandem, they deliver greater jetting force and faster response time, enabling precise, consistent dispensing of medium to high-viscosity hot melt materials. This makes them ideal for non-contact micro-dispensing in mobile phone mid-frames, mini tablet enclosures, and smart device assembly. The enhanced power of dual-piezo technology allows accurate dot and line dispensing at high speed, even under challenging temperature and viscosity conditions. Their modular, heat-stable design ensures long-term reliability and minimal maintenance, supporting automated, high-throughput production lines.

FAQ

Q1: Can the valve integrate with automated production lines and vision systems?
Absolutely. The valve supports high-speed signal response and can be seamlessly integrated with vision-guided dispensing platforms, robotic arms, and high-speed SMT lines, enabling precise, repeatable, and fully automated operation.

Q2: How does the valve ensure consistent dispensing quality for high-mix production?
A2: Its dual-actuation design minimizes performance variation due to adhesive viscosity changes or ambient temperature fluctuations, maintaining stable jetting quality across different product types and production conditions.
