Based on independent R&D and technological innovation, Quark Research Institute continuously optimizes product structure and enhances performance in response to market demands. Its specialized technologies in automated micro-dispensing, precision filling, and coating are now recognized and widely adopted across multiple industries.

Quark Research Institute (Kunshan Quark Industrial Technology Research Institute Co., Ltd.) is a technology enterprise dedicated to precision dispensing solutions and localized services. Grounded in independent R&D and innovation, we constantly refine our product portfolio and capabilities to meet market needs. Our expertise in automated micro-dispensing, precision filling, and coating technologies has gained recognition and application in numerous fields.

The DOT Series Non-Contact Piezoelectric Jetting System, launched by Quark Research Institute, holds multiple independent intellectual property rights. Its product line includes core components such as high-precision micro-dispensing valves and control systems.

Currently, leveraging its current-mode fluid control method, the piezoelectric jetting system is valued for its fast, precise, and sustained operation. It is extensively applied in sectors including high-end display manufacturing, SMT & PCB assembly, wearable devices, new energy applications, assembly dispensing, and module production, as well as in industries like life sciences and military products. Quark enables innovative R&D in high-precision fluid control technology and stands as a trusted partner.

Quark Piezoelectric Valve Kit
The high-precision piezoelectric jet valve, independently developed by Quark Research Institute, utilizes an advanced piezoelectric ceramic drive mechanism. It achieves a dispensing accuracy of ±1%, a minimum single-droplet volume of 0.1 nl, and can process fluids with viscosities ranging from 1 to 200,000 mPa·s. It excels at dispensing straight lines, arcs, and complex patterns with minimal issues like splatter or irregular dot shapes. Its superior performance and precise fluid control technology have earned consistent praise within the industry.

Furthermore, the DOT Series Non-Contact Piezoelectric Jetting System can be freely configured with high-performance modules such as valve controllers, heating controllers, and heating units for liquid reservoirs, adhesive barrels, and supply lines, along with a wide selection of accessories including various specifications of needles and nozzles. This enables the implementation of high-precision fluid processes across diverse scenarios and provides Quark’s professional, customized fluid solutions.

To date, the Quark DOT Series Non-Contact Piezoelectric Jetting System has undergone four generations of iterative innovation: the initial piezoelectric valve, the bubble- and splash-suppression piezoelectric valve, the variable-frequency and touchscreen piezoelectric valve, and the quick-disassembly piezoelectric valve. A previous version of the piezoelectric valve used for silver adhesive dispensing on LCD panels has operated stably on a customer’s production line for over 25,000 hours, achieving no fewer than 1 billion dispensing cycles while maintaining high-quality process performance.
