Musk accelerates Optimus mass production, can humanoid robot precision parts processing factory seize new opportunities?

Recently, Musk posted a big photo of the Optimus robot production line at the Fremont factory on social media platform X, with the caption "Visiting the Optimus production line". As soon as the news came out, it sparked heated discussions in the industry, and everyone believed that this may represent Tesla's humanoid robot Optimus entering a critical mass production stage.

It is worth mentioning that Tesla's Fremont factory has always been the company's pioneering manufacturing center in the United States. The original Tesla flagship model production line has been changed to the current humanoid robot production line. The transformation of production capacity means that Optimus robots will become the core production pivot for Musk's layout of universal humanoid robots in the future. The curtain has been drawn for the mass production of humanoid robots. For precision parts manufacturers in the upper and middle reaches such as Huiwen Zhizao, the trillion dollar new track has officially ushered in an order explosion window, which is both an opportunity and a challenge.

This article will focus on the difficulties in mass production of robots, and break down the three core pain points of current industry costs, technology, and scenarios from the perspective of precision parts manufacturers. At the same time, combined with the actual processing experience of Huiwen Zhizao, we will discuss how upstream and midstream suppliers can meet this demand.

Cost bottleneck for mass production of humanoid robots

In terms of cost bottleneck, actuators (including motors, reducers, and screws) account for 40% -50%, making them the most valuable single component module. From the perspective of mainstream models in the industry such as Tesla Optimus, Yushu, Zhiyuan, etc., a humanoid robot requires approximately 14-30 reducers and more than 30 planetary roller screws for its entire body. The value of these core transmission components alone exceeds half of the entire machine.

Why can't the cost be reduced? The core reason lies in the processing stage - these parts have special materials (high-temperature alloys, high-precision bearing steel), complex structures (such as thin-walled cavities, micro threads), and extremely high precision requirements, which make it difficult to improve the yield rate and result in high single piece processing costs.

Taking the harmonic reducer as an example, its core flexible wheel is a thin-walled cup-shaped structure with a wall thickness of only 1-2mm, which is prone to deformation during the machining process. The requirements for clamping scheme, cutting parameters, and tool selection are very strict. During batch processing, if a certain parameter is unstable, the entire batch of parts may exceed the tolerance and be scrapped, resulting in a direct doubling of costs.

For precision robot parts manufacturers like Huiwen Zhizao in Shenzhen, the core path to cost reduction is not to compress profits, but to improve yield through process optimization and reduce rework waste through batch consistency control. For example, in the processing of reducer housing, using a unified benchmark clamping+online size detection between processes can increase the batch qualification rate from the industry average of around 85% to over 95%, and naturally reduce the cost of individual pieces.

Technical barriers to mass production of humanoid robots

In terms of technological barriers, there are mainly three points: large-scale yield control of precision core components, real-time stability of complex motion and embodied intelligent algorithms, and safety certification and cost balance in multiple scenarios. ‌‌

The first barrier is directly related to the precision manufacturing end in the upper and middle reaches. The control of large-scale yield lies in achieving high precision in single piece sampling, but it is not easy to control high-precision yield in mass production. The tolerance requirements for the core components of humanoid robots are very strict. During batch processing, factors such as tool wear, temperature changes, and clamping deformation are combined, and the yield rate can easily drop from 90% to below 70%. For processing plants like Huiwen Zhizao, yield is cost - between 95% and 80% yield, the cost of a single piece may differ by more than 30%.

The second barrier belongs to the software control level of the entire machine. The stability of embodied intelligent algorithms is necessary to ensure the synchronous linkage of dozens of degrees of freedom of humanoid robots, involving multiple aspects such as motion control, perception, and decision-making. However, the real-time stability of algorithms requires precise hardware support. The backlash of reducers with dozens of joints exceeds the tolerance, the accuracy of screw lead is insufficient, and the installation position of sensors is slightly offset, all of which can cause distortion in the motion control of the entire machine.

The third barrier runs through the entire process of landing. On the one hand, if humanoid robots enter commercial and household scenarios, they need to pass strict safety certification, which has strict requirements for the fatigue life, reliability, and consistency of parts; On the other hand, processing enterprises cannot only pursue accuracy, but also control costs while ensuring accuracy, which forces these enterprises to adopt new process solutions to meet their needs.

The combination of these three barriers requires precision parts manufacturers in the upper and middle reaches to have stable batch precision machining capabilities, technical reserves of multiple materials and processes, and the ability to find a balance between precision and cost. Many precision machining parts manufacturers in Shenzhen have the ability to quickly seize the benefits of the trend. For example, Shenzhen Huiwen Intelligent Manufacturing relies on its own design, intelligent manufacturing, and assembly integrated full chain service capabilities, innovatively adopting the combination of "new materials+new molds+precision machining" process, which can meet different needs from single piece sampling to medium to large batch production, and help customers achieve rapid batch delivery.

The problem of missing scenes in the mass production of humanoid robots

From the perspective of robot mass production scenarios, we mainly look at home and industrial scenarios, both of which have not yet formed a commercial closed loop of "demand cost value". In family settings, low-priced specialized equipment such as floor scrubbers and accompanying devices have mature functions and affordable prices, which can basically meet the needs; In industrial scenarios, the use of specialized robotic arms is more efficient, suitable for standardized assembly line operations, and has a much higher overall operational efficiency than current humanoid robots. Humanoid robots only have unique advantages in small enclosed workstations, high-risk inspections, and flexible switching of multiple processes. However, the market size of these segmented applications is limited and difficult to support large-scale production in complete machine factories.

Insufficient demand on the scene side will also constrain the development of the upstream and midstream parts industry in reverse: the scale of complete machine orders cannot increase, and precision machining manufacturers cannot dilute equipment, molds, and process research and development costs through large-scale production. The unit price of high-precision titanium alloy joints, micro transmission parts, and other components remains high, further raising the price of robot complete machines and falling into a cycle of "low demand → low output → high cost → less demand". To break this deadlock, on the one hand, it is necessary for machine manufacturers to continuously iterate algorithms and expand irreplaceable universal functions; On the other hand, it is also inseparable from the continuous optimization of processing technology by precision machining enterprises in the upper and middle reaches such as Huiwen Zhizao, which steadily improves batch yield and compresses component manufacturing costs, laying a cost foundation for the landing of humanoid robots in various commercial and household scenarios.

Overall, the countdown to Optimus mass production has begun, marking the official departure of the humanoid robot industry from conceptual hype and entering the hardcore commercialization stage of "process implementation, capacity realization, and cost competition". The bottleneck of the industry has never been limited to the integration of AI algorithms and complete machines, but is also hidden in every process, every tolerance, and every batch delivery of precision manufacturing in the upper and middle reaches.

The competition in the future humanoid robot race relies heavily on precision manufacturing capabilities in the supply chain. Upstream and midstream enterprises that can simultaneously overcome high-precision process barriers, scale yield challenges, mass production cost control, and stable delivery challenges will continue to occupy the core supply chain seats of leading machine manufacturers, leading the trillion yuan humanoid robot new track and becoming the core supporting force for industrial scale landing.

For processing plants like Huiwen Zhizao, which have experience in large-scale production, the advantage lies in the production capacity of 20000 square meters of factory buildings and 370+processing equipment, as well as the ability to provide integrated design, intelligent manufacturing, and assembly services throughout the entire chain. In the context of accelerating the humanoid robot race track, the full process capability of "being able to sample, produce energy, and deliver continuously" is the core consideration for downstream customers when choosing suppliers.
