The market demand for high-precision hardware parts and components is showing a steady growth trend, driven by the development of various downstream industries. In the industrial robot industry, precision gears, bearings, and shafts are the core components of robot joints, which directly affect the flexibility and positioning accuracy of robots. With the continuous expansion of the industrial robot market, the demand for high-precision hardware parts is also increasing. In the new energy power generation field, precision hardware parts are used in wind turbines, solar power generation equipment, and energy storage systems, requiring high corrosion resistance and fatigue resistance to adapt to long-term outdoor operation. In addition, the rapid development of the electronic information industry has promoted the miniaturization and high integration of high-precision hardware parts, such as micro-precision connectors and micro gears, which are widely used in 5G base stations, smart wearables, and other products.
