Wenzhou QiMing Stainless Co., Ltd. Showcases Core Vacuum Products and High Purity Fittings at SEMICON Japan, Demonstrating China’s Precision Manufacturing Strength

Wenzhou QiMing Stainless Co., Ltd., established in 2015 and based in Wenzhou City, is a leading manufacturer and exporter of stainless steel valves and fittings. Our product range serves industries such as food, dairy, beverage, cosmetics, wine, semiconductors, LCD, solar energy, lithium technology, and photovoltaics. With advanced production equipment including Mazak CNC machines, milling CNC, handheld spectrometers, and helium mass spectrometer leak detectors, we ensure the highest standards of quality and precision across all our stainless steel valves and fittings.

For over 15 years, QiMing has focused on the R&D, manufacturing, and sales of stainless steel vacuum equipment and high purity fluid system components. Known for stable product quality and continuous technological innovation, we have built an excellent reputation in the domestic market. Our sales network covers the entire country, serving research institutes, high-end equipment manufacturers, and customers in the semiconductor sector. Our participation in SEMICON Japan marks a key step in expanding into international markets and meeting the cutting-edge demands of the global semiconductor industry.

Exhibition Highlights: Comprehensive Range of Vacuum and High Purity Solutions

At this year’s exhibition, QiMing presented a targeted selection of critical products designed for ultra-high vacuum and clean environments in semiconductor manufacturing, photovoltaics, and scientific research. The showcased lineup included:

• KF Fittings: A series of quick-connect, leak-tight vacuum fittings suitable for rapid assembly and maintenance of various vacuum systems.
• ISO Flanges: Large-diameter ISO flanges compliant with international standards, delivering higher conductance and stability for demanding applications.
• CF Flanges: Featuring metal seals (typically copper gaskets), our CF flanges ensure extremely low leakage and outgassing rates in ultra-high vacuum environments, meeting stringent semiconductor process requirements.
• Vacuum Valves: Including angle valves, gate valves, and baffle valves, demonstrating our expertise in precise control of vacuum flow paths.
• High Purity Tubing: BA (bright annealed) and EP (electropolished) grade stainless steel tubing and connectors that minimize particle generation and gas permeation to maintain the purity of process media.

These products reflect QiMing’s complete control over materials science, precision machining, welding technology, and surface treatment. In semiconductor manufacturing equipment, the reliability and cleanliness of the vacuum system directly impact chip yield and performance — precisely the core demand addressed by our vacuum valves, KF fittings, ISO flanges, CF flanges, and high purity tubing.

Global Interest and Positive Feedback

During the exhibition, QiMing’s booth attracted numerous visitors from Japan, South Korea, Southeast Asia, Europe, and the Americas, including equipment manufacturers, engineers, and procurement managers. Attendees expressed strong interest in the exquisite craftsmanship, comprehensive product categories, and internationally standardized designs of our stainless steel valves and fittings. Many engaged in in-depth technical discussions and business negotiations with our on-site teams. Several potential clients praised the high precision and quality of “Made in China” products, laying a solid foundation for further expansion in Asia and beyond.

Leadership Vision

A company representative stated:

“Participating in SEMICON Japan gives us the opportunity to benchmark against global leaders, learn advanced practices, and listen directly to customer needs. For 15 years, we have been rooted in Wenzhou, serving customers nationwide. Now, we want to showcase on this international stage that China also possesses strong design and manufacturing capabilities in high-end vacuum components. The stability and advancement of the semiconductor supply chain require global collaboration, and we look forward to integrating into this chain with high-quality products and solutions that create value for our customers.”

Conclusion

Our presence at SEMICON Japan was not only a successful display of products and technologies but also a powerful brand promotion on the international stage. It marks a confident step for Wenzhou QiMing Stainless Co., Ltd. toward becoming a trusted supplier in the global vacuum and high purity fluid system market. In the tide of global competition, QiMing is polishing a new name card for Chinese precision manufacturing with its commitment to “craftsman spirit.”
