Industry View > Another manufacturing giant lands a $5 billion robot order from Tesla—marking a breakthrough moment for the humanoid robotics sector!
Keywords: Sanhua Intelligent Controls Secures 5 Billion Yuan Robot Joint Deal from Tesla, Marking the Start of Mass Production for Humanoid Robots.
Sanhua Intelligent Controls, a global leader in thermal management systems, is making a remarkable transformation—from an automotive parts supplier to a dominant player in robotics, thanks to a massive order from Tesla. In early October 2025, a video showcasing Tesla’s Optimus humanoid robot smoothly performing complex tasks sent shockwaves through the global tech community. Behind this historic breakthrough lies the strong support of a Chinese company: Sanhua Intelligent Controls.
In late September, Sanhua secured a **5 billion RMB** order from Tesla for its linear joint products. Deliveries are set to begin in phases starting from the first quarter of 2026. This monumental contract signals that the humanoid robotics sector has officially moved from the realm of "concept hype" into a new era marked by "performance realization."
01 The Cornerstone of the Order
Following the announcement of a 20 billion RMB collaboration deal with Tesla at the end of September, Sanhua once again clinched a major exclusive order worth 5 billion RMB for its linear joint components in the robotics field. This order is expected to start shipping from the first quarter of 2026. Based on industry estimates of the value of a single linear joint for a robot, the order corresponds to manufacturing plans for at least 180,000 Optimus units.
Market observers note that this volume "far exceeds previous market expectations for Tesla's 2026 production capacity" (estimated around 100,000 units), highlighting Tesla's unwavering confidence—and urgent timeline—in scaling up and commercializing the Optimus platform. Beyond linear joints, Sanhua is also the global exclusive supplier of Optimus' rotary joint assemblies and liquid-cooling modules, holding a supply chain share of 50% to 70% for robotic actuators.
02 Technological Barriers
Sanova’s ability to secure Tesla’s core robotic joint orders wasn’t due to luck—it stems from decades of deep-rooted technological expertise. The company has successfully "downsized" its liquid-cooling technology, originally developed for automotive thermal management, and applied it to robotic joints, effectively solving the critical issue of overheating under high loads.
Sanova’s innovative micro-liquid cooling system keeps actuator temperatures within 10°C even in environments as hot as 45°C, reducing failure rates by 60% compared to air-cooled solutions. Additionally, their advanced rotary actuators achieve a torque density of 35 Nm/kg—20% more powerful than Boston Dynamics’ Atlas robot—and integrate planetary roller screw mechanisms capable of delivering torque precision down to 0.1 mm. These cutting-edge features outperform international competitors by threefold.
As of August 2025, Sanhua has already filed 127 patents related to robotic actuators, including 61 invention patents, creating formidable barriers that make it extremely challenging for newcomers to catch up.
03 Production Capacity Strategy
To align with Tesla’s aggressive mass-production schedule, Sanhua has proactively positioned its manufacturing capabilities worldwide, establishing a robust network of "domestic R&D + global manufacturing." For instance, the company’s 3.8 billion RMB investment in the Qiantang base in Hangzhou will ramp up to 1 million actuator production units annually by 2026, positioning it as a key "bridgehead" for Tesla’s Asia-Pacific supply chain.
Meanwhile, the first phase of Sanhua’s joint venture facility in Monterrey, Mexico, is designed to produce 300,000 robotic actuators per year and is slated to begin operations in the second half of 2025, enabling localized support for Tesla’s Texas Gigafactory. Sanhua’s Thai plant has also been integrated into its robotics business strategy, further solidifying its role as a global supply chain powerhouse.
This strategic combination of "order anticipation + capacity readiness" ensures that Sanhua is well-prepared to meet Tesla’s future demand for 50,000 units—or even scaling up to millions of units—of Optimus robots.
04 Contribution to Company Performance
Industry analysts predict that Sanhua’s robotics business will contribute 3.5 billion RMB in revenue by 2026, effectively "recreating another Sanhua." Specifically, with Tesla expected to produce 50,000 Optimus units in 2026, Sanhua’s projected market share stands at 70%. Given the average price of 50,000 RMB per actuator, this translates to a total revenue of 3.5 billion RMB.
Assuming a gross margin of 22% and a net profit margin of 10%, this partnership could generate a healthy 350 million RMB in net profits for Sanhua. Looking ahead, if Optimus production scales up to 2.25 million units by 2030, with Sanhua maintaining a 50% market share, revenues could soar to 33.8 billion RMB, translating into a staggering 6.8 billion RMB in net profits—equivalent to 2.3 times the company’s entire net profit in 2023.
05 Supporting Its Core Business
On the eve of the robotics boom, Sanhua’s traditional core businesses continue to provide a stable foundation for growth. In the first half of 2025, the company reported revenue of 16.263 billion RMB, representing an impressive 18.91% year-over-year increase. Net profits attributable to shareholders reached 2.11 billion RMB, soaring 39.31% compared to the same period last year.
In particular, the refrigeration and air-conditioning components segment generated 10.4 billion RMB in revenue, up 25% YoY, with core products like electronic expansion valves capturing over 50% of the global market share. Through its 13 overseas factories located in Poland, Thailand, Vietnam, and Mexico, Sanhua maintains an overseas revenue share consistently above 45%, effectively mitigating the impact of U.S. tariffs. This resilient business model—capable of generating consistent profits while weathering external risks—provides ample "ammunition" for the company’s ambitious expansion into emerging markets like robotics.
06 The Four Giants Compete
The humanoid robotics sector has emerged as a new battleground for China’s high-end manufacturing industry. Sanhua Intelligent Controls, Lingyi Manufacturing, Top Group, and Inovance Technology have collectively earned the nickname "The Four Giants of Humanoid Robotics." Among them, Sanhua stands out with its integrated "thermal management + motion control" solution, giving it a significant edge in the competitive landscape.
Lingyi Manufacturing focuses on structural components and sensors for robotics, particularly excelling in hand sensors that can precisely detect object weight and temperature with errors controlled within 0.1 grams. Meanwhile, Top Group, a key supplier of actuators for Tesla’s Optimus robot, boasts linear actuators with lifespans reaching 20,000 hours—double the industry average.
Inovance Technology, on the other hand, adopts a "full-industry-chain approach," leveraging its strengths in "motors + controllers" to capture a substantial share of the market. While these four companies compete fiercely, their rivalry isn’t a zero-sum game—they’re instead driving collaborative growth across the entire robotics ecosystem, helping to mature China’s domestic humanoid robotics industry as a whole.
With Tesla positioning the Optimus humanoid robot as a strategic cornerstone of its future, Sanhua Intelligent Controls—holding both exclusive supply rights and confirmed production capacity—stands poised to enter a golden era of synergistic growth between its established core business and its burgeoning robotics venture.
From being a leading manufacturer of air-conditioning components to becoming a dominant force in new energy thermal management, and now firmly establishing itself as the "gatekeeper" of robotic joints, Sanhua Intelligent Controls continues to navigate each transformative phase with precision, perfectly aligned with the rhythm of industrial upgrading. Standing at the intersection of two super-mega trends—new energy vehicles and AI-driven robotics—this Chinese enterprise’s journey as the "Joint King" is just beginning.
