Heat treating equipment setters, operators, and tenders in the metal and plastic industries are responsible for controlling the processes that heat, cool, and treat materials to change their physical and chemical properties. These professionals set up and operate machinery that applies heat to metals and plastics to enhance their strength, ductility, corrosion resistance, and other material characteristics. They typically work with equipment like furnaces, kilns, and ovens, and may also handle quenching systems that involve cooling materials rapidly after heating. The role requires a strong understanding of the materials being treated, as well as the heat treating processes, including annealing, hardening, tempering, and sintering. Attention to detail, precision, and a commitment to safety are essential, as the processes can involve high temperatures and hazardous materials. Overall, the work is critical to ensuring that components used in various applications—ranging from aerospace to automotive to manufacturing—meet specific performance standards and regulatory requirements.
