Robotic Material Handling in Heat Treatment

by Dennis Beauchesne, ECM USA General Manager

Robotic material handling is rapidly transforming modern heat treat operations traditionally dependent on manual loading and batch transfer. As heat treaters face increased pressure to improve throughput and working conditions while maintaining strict quality standards, automation has become a strategic investment.

Heat treat material handling is more than simple part movement. Parts must first be positioned onto fixtures or loaded into bins, transferred and placed into the furnace, then moved again for quenching and/or tempering – sometimes under undesirable conditions depending on the installed technology. Additionally, the automation system must also deal with the dunnage that the parts are contained. Dunnage can also be stored in the heat treat area and handled by automation. Robotics and automation excel in this process because of the efficient repeatability that is difficult to achieve with manual operations.

Robotic Advantages

The most significant advantages of robotic material handling are repeatability, consistency and reduction of work force. Robots execute the same motions cycle after cycle which ensures uniform loading and proper spacing between parts within fixtures or baskets. For example, in vacuum furnaces, correct part placement is essential to achieving even heat distribution and minimizing distortion. Automated loading eliminates error caused by human fatigue or procedure changes, leading to more consistent and desirable metallurgical results and reduced scrap/re-work…
