KGL Humanoid Robot Components include robot arm structural frames, internal aluminum upper covers, joint transmission shafts and load-bearing support brackets, manufactured via 4/5-axis CNC multi-surface simultaneous milling. We select high-rigidity aluminum alloys to balance lightweight design and structural load capacity, with precise matching holes and bearing seats to ensure smooth joint rotation without jitter. All parts support customizable anodizing, wire drawing and anti-wear surface coating processes. Our factory realizes stable batch production with consistent dimensional repeatability, effectively solving the precision matching pain points of multi-joint humanoid robots. Widely applied in service robots, industrial collaborative robots and educational humanoid robot projects for global automation clients.
