Expands Oxygen Sensor Production Workshop to Meet Growing Global Demand

HEFEI, China – June 30, 2026 – Hefei Ruimin Electronic Technology Co., Ltd., a fast-growing manufacturer of high-end oxygen sensors, today announced the full-scale operation of its expanded production workshop located in the Hefei High-Tech District. The 1,000-square-meter facility, staffed by a dedicated team of 30 production specialists, represents a significant milestone in the company's commitment to delivering OE-quality oxygen sensors to automotive and industrial markets worldwide.

Since its establishment in 2021, Hefei Ruimin has rapidly emerged as a competitive player in the global oxygen sensor industry. The company has developed and mass-produced more than 1,000 types of oxygen sensors, serving diverse applications including automotive engine management systems, household appliances such as ovens and gas water heaters, medical devices including ventilators and oxygen concentrators, as well as industrial gas analysis equipment. The expanded workshop enables the company to meet surging order volumes while maintaining the rigorous quality standards that have become its hallmark.

The newly optimized 1,000-square-meter workshop exemplifies modern lean manufacturing principles. The production floor is organized into dedicated zones for component assembly, ceramic chip integration, precision welding, calibration testing, and final quality inspection. Each station is equipped with specialized tooling and testing apparatus designed specifically for oxygen sensor manufacturing.

A key feature of the workshop is its proprietary precision spot-welding equipment for wire terminals—a technology for which Hefei Ruimin has secured a utility model patent. This in-house developed solution ensures consistent, reliable electrical connections critical to sensor performance and longevity. The workshop also incorporates automated feeding systems, camera-assisted inspection stations, and dust-removal systems to maintain the clean environment essential for sensitive ceramic sensor elements.

Quality control is embedded throughout the production process. Each sensor undergoes multiple verification steps, including dimensional inspection, electrical characteristic testing, and functional calibration against reference standards. The company's professional R&D team continuously monitors the latest international scientific research and technological advancements to refine production procedures and drive continuous innovation.

"Our 30-person workshop team is the backbone of our manufacturing operations," said Mr. Zhu, a company representative. "Every production staff member undergoes comprehensive training, and our standardized procedures ensure that each sensor leaving our workshop meets the same high-quality specifications, whether destined for the Middle East, North America, South America, or Europe."

Hefei Ruimin's oxygen sensors have gained recognition from customers across multiple continents. The company's professional international sales team, led by a manager with over a decade of oxygen sensor sales and after-sales service experience, has established a robust distribution network spanning global markets. The company supplies sensors to the automotive aftermarket, appliance manufacturers, medical equipment producers, and industrial gas monitoring system integrators.

The global oxygen sensor market continues to demonstrate strong growth. The automotive oxygen sensor segment alone was valued at US$34.6 billion in 2024 and is projected to reach US$46.4 billion by 2030, growing at a compound annual rate of 5%. The broader oxygen gas sensor market is expected to expand with a CAGR of 6.1% from 2025 to 2031, driven by increasing environmental safety regulations and the growing adoption of oxygen sensors in vehicles and industrial monitoring applications.

The expanded workshop operations align with Hefei's strategic vision for advanced manufacturing and electronic technology development. The city's "15th Five-Year Plan" emphasizes strengthening leading industries including新一代信息技术 (next-generation information technology), new energy, and high-end equipment manufacturing, with a focus on the "Chip-Screen-Vehicle-Integration" industrial ecosystem. As a key supplier in the automotive electronics supply chain, Hefei Ruimin is well-positioned to benefit from local initiatives aimed at deepening industrial chain collaboration and increasing localization of key components.

With the expanded 1,000-square-meter workshop operating at full capacity, Hefei Ruimin Electronic Technology Co., Ltd. is poised to further strengthen its position in the global oxygen sensor market. The company plans to continue inve
