From September 9 to 11, 2026, the 27th China International Optoelectronics Expo successfully concluded at the Shenzhen International Convention and Exhibition Center. At this year’s event, Beijing AccuFlow Technology (ACCU) Showcasing its core products developed and manufactured in-house, along with customized solutions. Optical Vacuum Coating Pavilion, Booth 7B17 , engaging in in-depth discussions with professional attendees, industry experts, and partners from the optoelectronics, semiconductor, photovoltaic, and new materials sectors, to jointly explore the applications and innovations of precision fluid measurement and control technologies in high-end manufacturing. 

I. Based on independently developed technologies   Supporting high-end manufacturing 

Looking back on the three-day exhibition, attendees showed particular interest in gas flow and pressure control in the fields of vacuum coating, semiconductor thin films, and new‑material coatings. In particular, in CVD and certain PVD processes, although gas flow controllers do not directly participate in film formation, they nonetheless influence the stoichiometry of reactive gases, the stability of the deposition process, and the thickness, uniformity, and overall quality of the resulting film—making them a core, critical component of high‑end precision manufacturing. 

ACCU On display in this集中 exhibition A full range of core products, including gas mass flow controllers/flow meters, Coriolis mass flow controllers/flow meters, pressure controllers, and gas–liquid mixing evaporation systems. , thanks to its stable performance, stringent precision, and scenario-specific customization capabilities, it has become the center of attention at the exhibition.

As a standout product at this on-site consultation, the ACU20FD gas mass flow controller/flow meter has earned widespread recognition thanks to its proven performance. This series employs the capillary‑tube heat‑transfer differential‑temperature calorimetric principle to measure gas mass flow, ensuring independence from temperature and pressure variations. It features short warm-up time, minimal zero drift, high accuracy, and fast response; its tubular分流 design is resistant to clogging, making it suitable for a wide range of low- and high-pressure pipelines. Meanwhile, for different application scenarios, The ACU20FD supports custom solutions such as all‑metal sealing, normally open valves, and high‑pressure variants, further addressing the diverse requirements of various process environments. In terms of communication compatibility, the ACU20FD supports RS‑232/RS‑485 interfaces and is compatible with a wide range of industrial communication protocols, including Modbus, DeviceNet, PROFINET, EtherCAT, and PROFIBUS, enabling flexible integration with various automation control systems. The ACU20FD enables rapid, precise control of gas flow and is widely applicable to gas distribution systems, vacuum coating, and other precision gas‑control applications. , providing reliable support for the stable operation of the process. 

2. Coriolis mass flow controller/flow meter

Faced with increasingly complex process conditions in high-end manufacturing sectors such as semiconductors, optoelectronics, and new materials, ACU20FE Series Coriolis Mass Flow Controller/Flow Meter It also garnered widespread attention from on-site customers. This series is based on the Coriolis force measurement principle, addressing the core requirements of precise micro‑flow control. It simultaneously measures mass flow rate, fluid density, and temperature. Unaffected by fluctuations in pressure, temperature, density, conductivity, viscosity, and other operating conditions, it offers exceptional environmental robustness and control stability, meeting the stringent flow‑measurement and control standards of cutting‑edge fields such as semiconductors and advanced optoelectronic materials, thereby helping to improve process yield. 

3. Gas–Liquid Mixed Evaporation System 

In applications such as thin-film deposition, where precise control of the gas–liquid mixing ratio is essential, the ACU20CEM gas–liquid mixing evaporation system demonstrates its technological prowess in the field of precision fluid control. The system comprises a liquid flow controller, a gas mass flow controller, and a temperature‑adjustable mixing evaporator, among other components. Utilizing advanced control technologies, it enables precise measurement and regulation of liquid flow rate, carrier gas flow rate, and evaporation temperature, ensuring that the gas–liquid molar ratio remains stable and free from drift over long‑term operation. During thin-film deposition, it ensures highly consistent gas‑flow control, making it well suited for high‑precision gas–liquid mixing processes such as semiconductor thin-film deposition. 

II. In-depth Communication   Focusing on industry needs

During the exhibition, ACCU The booth attracted numerous industry peers from both China and abroad, who stopped by to engage in discussions covering a wide range of topics, including product selection, technical specifications, process applications, system integration, and customized requirements. ACCU The team engaged in in-depth discussions with the customer and, based on the customer’s actual operating conditions, provided tailored technical support and customized product solutions. 

From a specific application requirement to a discussion of technical specifications; from selecting a single product to exploring an integrated fluid‑control solution—each exchange is… ACCU An important opportunity to deepen our understanding of customer needs and refine our products and services. Meanwhile, every question raised on-site continually prompts us to ask: How can we make our products more precise? How can we enhance system stability? And how can domestically developed precision fluid‑control technologies better support high‑end manufacturing? 

III. Technology Has No End   Innovation never stops.

From a single product to diversified offerings, from standard products to customized solutions, ACCU We consistently uphold innovation-driven development, continuously break new ground, steadily enhance our product portfolio and manufacturing capabilities, and continually elevate both product performance and service quality. 

In the face of ever-escalating technological demands across the optoelectronics, semiconductor, new energy, and high-end manufacturing sectors, ACCU We will continue to deepen our expertise in the precision fluid measurement and control field, proactively addressing market demands with products and solutions that are even more stable and precise. 

IV. The closing does not mark the end; we keep moving forward.

Although the three-day exhibition has come to a close, every face-to-face interaction, each technical discussion, and every piece of customer feedback is contributing to… ACCU Continuous innovation and product upgrades are building new momentum. 

Thank you to everyone who has attended. ACCU To our existing and new customers, partners, and industry peers at the booth: thank you for your attention, recognition, and valuable exchanges. The conclusion of the exhibition is by no means the end; each encounter marks a new connection, and every trust placed in us fuels our continued progress.
