Zhejiang Micromagnetic Precision Technology Co., Ltd. specializes in the research, development, and manufacturing of ferrofluid-based products, primarily focusing on advanced sealing solutions. The company's core offerings include ferrofluidic vacuum rotary feedthroughs, which create hermetic seals for transferring rotational motion into vacuum or pressurized systems. These seals leverage ferrofluid, a liquid infused with magnetic nanoparticles, to form a liquid O-ring that offers low friction, high reliability, and long service life, preventing gas from entering or escaping.
The firm's products are engineered for demanding, high-reliability applications across various high-tech sectors. Key markets include semiconductor manufacturing equipment, medical devices, space technology, and scientific research, where maintaining a pristine vacuum or pressurized environment is critical. For instance, its ferrofluidic seals are utilized in equipment for chemical vapor deposition (CVD), sputtering systems, and single crystal silicon furnaces. The technology provides a superior alternative to traditional mechanical seals, especially in high-speed applications (up to 20,000 RPM) and environments requiring non-contamination and leak-free performance.
The company supports its clients by offering a range of standard and custom-designed feedthroughs to meet specific application requirements. It employs advanced manufacturing and analysis techniques, including thermal, magnetic field, and fluid analysis, to ensure product quality. The business serves original equipment manufacturers (OEMs) and end-users who integrate these specialized components into larger systems.
