Non-contact Micro dispensing Dual Piezo Jetting valve with controller for high viscosity glue

The dual piezo jet valve is an advanced dispensing solution designed for precision electronics applications such as smartphones, tablets, smartwatches, and wireless earbuds. Utilizing two piezoelectric actuators working in tandem, it delivers significantly greater jetting force and faster response time compared to single-actuator designs. This makes it ideal for high-viscosity adhesives and demanding micro-dispensing processes.

The valve ensures non-contact, high-frequency, and highly stable jetting with superior dot consistency and no stringing. Its ability to handle a wide range of materials—UV glue, epoxy, thermosetting adhesive, red adhesive—makes it a reliable choice for applications like frame bonding, camera module encapsulation, and MEMS packaging.

The dual piezo structure enables precise control in narrow spaces, improving production efficiency and yield. With high-speed dispensing over 1000Hz and consistent performance, the dual piezo valve is the preferred solution for advanced electronics assembly lines.

FAQ

Q1: What types of adhesives can the dual piezo jet valve handle?
A1: The dual piezo valve is designed to dispense a wide range of adhesives, especially high-viscosity materials such as epoxy, UV glue, silicone adhesives. Its dual actuator design provides stronger jetting force, making it ideal for difficult-to-jet fluids.

Q2: How does the dual piezo structure improve dispensing performance?
A2: By using two piezoelectric actuators, the valve delivers higher force and faster response time. This ensures better control over droplet volume, more consistent dot shapes, and reliable jetting even at high speeds (up to >1000Hz), especially critical for micro-dispensing in compact devices.

Q3: Is the valve suitable for ultra-small and narrow areas in devices like TWS earbuds and smartwatches?
A3: Yes. The dual piezo valve features non-contact dispensing with ultra-high precision, allowing accurate placement in confined or curved spaces without damaging components or causing overflow.
