Introduction:
In today's global wave of industrial automation, precision transmission technology, as the core "joint" of intelligent manufacturing, is constantly breaking through performance boundaries. As a key transmission component, the screw module has become a "hidden champion" in the field of high-end equipment manufacturing due to its high precision, high rigidity, and long lifespan, continuously promoting the innovative development of industries such as robotics, semiconductor equipment, and new energy production lines.
Screw module: the "heart" of precision transmission
The screw module is highly integrated with ball screws, linear guides, drive motors, and precision structural components, which can convert the rotational motion of the motor into high-precision linear motion. It is known as the "heart" of automation equipment. Compared to traditional transmission methods, its repeated positioning accuracy can reach ± 0.005mm, transmission efficiency can reach over 90%, and it has low noise and fast response, perfectly adapting to high-speed and high-precision scene requirements.
In recent years, with the deep integration of 5G communication, artificial intelligence, and IoT technology, screw modules have further evolved towards intelligence and modularity. Some leading enterprises have launched intelligent modules that integrate sensing and self diagnostic functions, which can monitor load status in real time, predict maintenance cycles, and provide guarantees for the stable operation of unmanned factories.
Localization breakthrough: from replacing imports to leading standards
In the past, the high-end screw module market was long monopolized by Japanese and German companies. However, according to the "2023 White Paper on China's Precision Transmission Industry", the market share of domestically produced screw modules has risen from 15% in 2018 to 35%. Some leading companies have successfully broken through technological barriers through material innovation (such as ceramic coating technology), process optimization (fully closed-loop grinding and processing), and customized design.
Our third-generation screw module is made of independently developed lightweight alloy materials, with a 20% increase in stiffness. At the same time, AI algorithms are used to optimize the preloading parameters, extending the service life to over 20000 hours, "said a technical director of a leading domestic enterprise. At present, domestically produced modules have been widely used in high-end equipment such as lithium battery laminating machines and photovoltaic string welding machines, and exported to Southeast Asian and European markets.
Setting sail on the trillion dollar track: driven by both policy and demand
At the policy level, the "14th Five Year Plan" for the development of intelligent manufacturing clearly states that by 2025, the CNC rate of key processes will exceed 68%, injecting a shot in the arm module industry. On the market side, the demand for emerging fields such as new energy vehicles, humanoid robots, and medical equipment is experiencing explosive growth. Taking humanoid robots as an example, a single unit needs to be equipped with 20-30 sets of screw modules, and the global annual demand is expected to exceed 10 million sets.
Industry experts predict that the global screw module market size will exceed 50 billion yuan by 2024, with a compound annual growth rate of 12.3%. In the future, with the increasing demand for miniaturization, corrosion resistance, impact resistance and other segmented scenarios, flexible supply chain enterprises with rapid response capabilities will seize the opportunity.
Conclusion:
From "manufacturing" to "intelligent manufacturing", every technological iteration of the screw module is writing a footnote for industrial upgrading. Under the dual opportunities of domestic substitution and global competition, Chinese precision transmission enterprises are using innovation as a blade to break through the waves in the sea of high-end manufacturing. Perhaps the next 'Chinese solution' to change industry rules is hidden within this delicate art.
