Primetals Technologies has announced a strategic partnership with Polytec, a global specialist in robotic and automation systems, to develop and commercialize TrimRob, an advanced robotic solution designed to automate trimming and sampling processes in wire rod mills. Positioned as the industry’s first foundry-rated robotic system of its kind, TrimRob marks a significant advancement in automation for long steel production.
The collaboration combines Primetals Technologies’ deep expertise in the long rolling sector with Polytec’s capabilities in robotics, artificial intelligence, and process automation. The result is a highly precise, repeatable, and self-contained system engineered to streamline coil finishing operations while improving overall plant efficiency.
Traditionally, coil trimming in wire rod mills has relied heavily on manual labour. The process is not only repetitive but also exposes operators to hazardous working conditions within congested areas of the production line. TrimRob addresses these challenges by integrating seamlessly into existing mill setups and automating critical tasks, thereby reducing reliance on manual intervention and enhancing workplace safety.
The system introduces a new approach to coil management by enabling efficient handling of a wide range of product sizes and steel grades. Its advanced design ensures consistent performance, allowing manufacturers to optimize throughput while maintaining operational reliability. By removing operators from high-risk zones, the solution contributes to a safer work environment and minimizes the potential for human error.
A key feature of TrimRob is its state-of-the-art vision system, which works in conjunction with a specialized trimming end-effector to deliver high levels of precision. The robotic system can accurately count individual coil rings, detect tangles or overlaps, and execute trimming and sampling operations autonomously. This level of automation ensures uniformity in output while significantly improving process consistency.
Beyond operational efficiency, the solution supports improved product quality by ensuring that trimming and sampling are performed with consistent accuracy. Wire rod mills adopting TrimRob can expect reduced maintenance requirements, better process control, and enhanced traceability across production cycles. The system also aligns with the broader industry trend toward digitalization and smart manufacturing, enabling producers to move closer to fully automated plant environments.
The partnership underscores a shared commitment by both companies to drive innovation in steel manufacturing through advanced technologies. By combining engineering excellence with next-generation automation, Primetals Technologies and Polytec aim to deliver solutions that not only improve productivity but also support sustainable and safe industrial practices.
