Sanhua Intelligent Controls

Business

Sanhua (浙江三花智能控制股份有限公司) builds its business on heat-pump and thermal-management technology: control components and subsystems for air conditioners and appliances, and valves, pumps and modules for cars. Beyond those, the company says it is expanding into electromechanical actuators for bionic (humanoid) robots (2026 interim report, p. 9). It has nine production bases worldwide, including four abroad in Mexico, Poland, Vietnam and Thailand (p. 11).

Results

In the first half of 2026 revenue rose 3.9% to ¥16.90bn and net profit attributable to shareholders fell 3.1% to ¥2.04bn (p. 7). Refrigeration and air-conditioning parts brought in ¥10.44bn (61.8%) and auto parts ¥6.46bn, up 9.9% (p. 13).

Robot actuators

Sanhua says its technology base in valves and pumps, thermal management, electromechanical actuation and system integration lets it move into robot actuators, and that it is building product development, customer validation and production capability (p. 11). For the first half of 2026 it says its robot electromechanical actuators were well received by customers and that core products are moving steadily through batch delivery and line ramp-up (p. 13).

The report does not give robot revenue, volumes, customers or capacity, and robots are not a reported segment, so the size of this business cannot be read from the filing.

Media reports on Tesla

Chinese media have linked Sanhua to Tesla's Optimus humanoid, but the company has not confirmed it. In October 2025 a rumour that Tesla had placed a US$685m order with Sanhua for linear actuators lifted its shares sharply; Sanhua published a clarification the same day saying the rumour was untrue and that it had no undisclosed material matters (IT之家, 15 October 2025). In September 2026 a Sanhua staff member, asked by a reporter about reports of a new Tesla audit in Ningbo, said they were not aware of it, and that the company is working with a major customer on robot joint actuators (IT之家, 19 September 2026). Media accounts differ on which actuator types Sanhua would supply.

Where it stands

Sanhua is a large, profitable maker of thermal-management parts with a robot option attached. Compared with Tuopu, which discloses robot actuator revenue and margin, Sanhua says less about its robot business in its periodic report.
