Against the backdrop of increasingly precise dispensing requirements, EHD technology—which integrates electric field effects with fluid dynamics—is being more widely adopted in dispensing, inkjet printing, and bonding scenarios. It provides robust support for high-precision, high-efficiency dispensing processes.

In response, Quark Research Institute has actively pursued breakthroughs in core EHD technologies, striving to translate its theoretical advantages into stable and reliable application capabilities. By expanding its series of EHD electrohydrodynamic applications, Quark meets the demands for even higher precision in dispensing and broadens the scope of industry applications.

· Evolving Technology Driven by Industry Demands and Challenges

Ultra-high precision, diverse functional materials, complex morphologies, and stable, controllable process quality… Advanced manufacturing scenarios impose stringent requirements on dispensing processes across multiple dimensions. Traditional technologies, limited by their mechanical principles, struggle to balance these demands.

In contrast, EHD electrohydrodynamic technology utilizes electrostatic field forces to directly drive and control fluids. Compared to traditional dispensing and inkjet methods, it achieves higher precision, broader fluid compatibility, and reduced adhesive waste.
