On November 25, 2025, Huichuan Technology, a leading domestic enterprise in the industrial control field, announced key operational data formed through research by multiple institutions. The core information indicates that the company’s large and medium PLC products have achieved a market share of approximately 5.1% in the domestic market, ranking sixth.
The Chinese large and medium PLC market has long been characterized by a “foreign capital dominance, domestic catch-up” pattern. The top five brands are all international industrial control giants, occupying over 70% of the market share. Siemens maintains its leading position with an estimated share of 45%-47%, with its large PLCs forming a near monopoly in sectors such as automotive manufacturing and high-end equipment due to deep technical accumulation and a complete ecosystem, resulting in strong customer loyalty; Mitsubishi and Omron, as representatives of Japanese brands, have stable audiences in the OEM equipment sector due to high adaptability and cost-effectiveness; Rockwell and Schneider hold advantages in high-end manufacturing and energy infrastructure sectors due to high reliability, especially in traditional heavy industrial scenarios such as metallurgy and petrochemicals, where foreign brands still have a first-mover advantage. Domestic brands are mostly concentrated in the mid-to-low-end market, struggling to break through the dual barriers of technology and market in the large and medium PLC sector.
Against this backdrop, Huichuan Technology has entered the sixth position in the Chinese large and medium PLC market with a market share of approximately 5.1%, becoming a rare domestic brand among the leading players in this sector. Behind this achievement is its continuous efforts in key technologies such as core algorithms, hardware integration, and software ecosystems, marking an important milestone for domestic brands in breaking the “technological hegemony” of foreign capital — it not only proves that domestic large and medium PLCs have the strength to compete with foreign products but also breaks the long-standing absolute advantage barrier of foreign brands, earning market trust for domestic industrial control products.
Huichuan Technology’s breakthrough path is highly representative: by focusing on core processes in industries such as photovoltaics, lithium batteries, and mobile phones, it has created a multi-product solution of “large and medium PLC + servo + inverter,” significantly enhancing customer loyalty; after launching a large redundant PLC product with functional safety in 2025, it has initiated trial verification in traditional fields such as metallurgy and petrochemicals and established model points, successfully breaking the monopoly of foreign brands in such scenarios.
This breakthrough has a strong driving effect on the entire domestic industrial control industry. On one hand, Huichuan Technology’s success will encourage more local enterprises to increase R&D investment in the mid-to-high-end PLC field, accelerating technological iteration in the industry; on the other hand, the rise of domestic brands will break the pricing monopoly of foreign brands, promote the cost-effectiveness of large and medium PLC products, reduce the automation upgrade costs for domestic manufacturing, and lay the foundation for the independent and controllable development of China’s industrial automation supply chain, supporting the implementation of the “Made in China 2025” strategy in the core control field.
In addition to Huichuan, domestic brands such as Zhongkong Technology, Holley, and Baoxin Software have also achieved breakthroughs in niche areas: Zhongkong Technology has established a foothold relying on the collaborative advantages of DCS systems in the chemical and petrochemical industries; Holley has accumulated stable shares in major infrastructure fields such as rail transit and nuclear power; Baoxin Software, backed by China Baowu, has deeply adapted to the complex scenarios of the metallurgy industry. These brands together form the core strength of domestic large and medium PLCs, steadily increasing the localization rate.
Shenzhen Huichuan Technology Co., Ltd. was founded in 2003, headquartered in Shenzhen, with permanent institutions and service centers in more than 30 countries and regions worldwide, employing over 20,000 people. In 2024, the total operating revenue reached 37.04 billion yuan, with a net profit of 4.29 billion yuan and R&D investment of 3.147 billion yuan. Its business is extensive, covering industrial automation, energy, industrial robots, smart elevators, industrial internet, new energy vehicles, rail transit, and other fields. Products include core components of intelligent equipment and robots (such as AC drives, servo systems, control systems, etc.), core components of new energy vehicle powertrains, rail transit traction and control systems, as well as industrial internet solutions.
Huichuan Technology’s rise to sixth place in the Chinese market is not only a breakthrough for a single enterprise but also a reflection of the leap from “catching up” to “running alongside” for domestic industrial control equipment. With continuous technological iteration, expanding application scenarios, and the dual drive of policy and market demand, domestic large and medium PLCs are expected to break the foreign monopoly in more key areas, and domestic leading brands represented by Huichuan will occupy a more important position in global market competition.
