What Challanges Will Meets for Customized Robotic & Automation Parts?
Complex Geometries & Tight Spaces
Robot joints, housings, and couplings often feature complex multi-axis geometries like deep holes and tight corners. These complicate tool path planning and extend cycle times. They also challenge conventional measurement, often requiring custom fixtures or non-contact inspection.
High Precision
In multi-joint serial robots, insufficient precision creates backlash, causing jitter, stalling, and loss of repeatability. Under long-term, high-frequency, high-load cycles, low-precision parts experience uneven force, accelerated wear, and excessive vibration. These issues lead to short-term accuracy drift, and long-term fatigue damage or equipment downtime.
Unique Materials Difficult to Process
To meet high-strength, lightweight requirements, robots often use carbon fiber composites, glass-reinforced plastics, titanium alloys, and specialty plastics (anti-static, flame-retardant, or thermally conductive). These materials demand advanced processes, equipment, and technical support.
Contradiction Between Design & Manufacturability
Ignoring manufacturability in robot part design will cause assembly nightmares, field failures, and endless rework. Robotic & Automation parts often demands repeated optimization and greater technical expertise to turn concepts into reality.
