• Advanced automated systems incorporate complex electrical architectures for power distribution functions, signal processing, and communication purposes. Industrial robots, automated assembly lines, CNC machines, and programmable logic controllers are highly dependent on wire harnesses for uninterrupted performance and optimal safety of complex automated systems in industrial manufacturing. Therefore, as industries become automated to improve manufacturing efficiency and product quality consistency, there has been an increasing trend of adopting customized wire harness solutions that can sustain in harsh industrial conditions involving continuous motions and electromagnetic radiation in automated manufacturing systems.
• According to the World Robotics 2025 report published by the International Federation of Robotics (IFR), nearly 393,700 industrial robots were operating in US factories as of 2025. Reflecting continued year-on-year growth, this was a 30% increase in annual installations compared to a decade ago, underscoring long-term structural shifts toward automation despite the fluctuation in installation numbers over the short term. Meanwhile, China has become the leading force in industrial robotics, with a record number of 2,027,000 operational robots and annual installations reaching 295,000 units in 2024, representing over half of global demand. Such rapid expansion within manufacturing facilities increases the need for advanced wire harnesses that support power delivery, motion control, sensor integration, and high-speed data transmission with maximum immunity against electrical noise within automated environments. As the robotic density increases, particularly in China and more slowly in the US, manufacturers increasingly require robust, flexible, and application-specific wire harnesses that ensure reliable performance, system scalability, and minimum downtime, driving global wire harness market growth.
