Robot components are manufactured using a special ductile iron casting process, with a tensile strength ≥700MPa and yield strength ≥550MPa, capable of withstanding 24-hour continuous load operations without bending or deformation.

1. The dimensional tolerance of key castings is controlled within ±0.01mm, with an accuracy of IT6 level, perfectly matching the installation requirements of the robot servo motor and reducer, ensuring joint rotation error ≤0.005°, achieving millimeter-level operational precision.

2. A low-temperature aging treatment process is adopted, with an internal stress relief rate of over 98%, preventing fatigue cracks caused by long-term high-frequency movement, ensuring the overall service life of the robot, and reducing the frequency of core component replacement.
