The four-day training sessions introduce participants to metalworking through online and in-person training.
Michael De Cicco checked the temperature a few times.
Clad in a silver heat-reflective suit, De Cicco, a mechanical engineering teaching faculty member at the University of Wisconsin–Madison, peered through his helmet’s drop-down visor at a high-temperature thermometer. Beside him, PhD student Rogelio Herrera had just dipped a sensor into a crucible filled with incandescent molten metal.
“That’s 970 degrees,” De Cicco told the 12 participants gathered around the grated floor in the middle of the foundry in the UW–Madison Art Lofts. “Celsius.”
That’s 1,778 degrees Fahrenheit.
It was day three of the second Metallurgical Engineering Trades Apprenticeship & Learning, or METAL, bootcamp at UW–Madison, held in late August 2026. Hosted by the UW–Madison College of Engineering in partnership with IACMI – The Composites Institute, the bootcamps introduce participants to metalworking through online and in-person training.
UW–Madison is one of 17 institutions in a growing national METAL network, which is expanding access to casting, forging and manufacturing training in an effort to develop a skilled workforce and secure the nation’s defense industrial base.
Consisting of nearly 120 foundries and employing 18,000 people in communities across the state, metalworking contributes more than $11 billion to Wisconsin’s economy, and the industry supports mining, construction, transportation, consumer products and military applications, according to the Wisconsin Cast Metals Association. This breadth, along with UW–Madison’s strengths in manufacturing and materials engineering, makes the university a strong fit for the program.
Inspiring people to pursue careers in metal casting and forging continues a longstanding tradition in Wisconsin, which has the most foundries per capita of any state in the United States, says Frank Pfefferkorn, a UW–Madison professor of mechanical engineering who leads the university’s METAL program. “Anyone who is interested can participate in the hands-on experiential bootcamps — no prior knowledge or experience is required,” he says.
The bootcamp’s lessons included forging and casting methods; modeling, heat treating and measuring the properties of differently processed alloys; pouring aluminum and brass medallions; and polishing finished pieces on the final day. Castings took place in the Art Lofts foundry, a facility shared by the UW–Madison Art Department and the College of Engineering.
With the temperature confirmed, De Cicco and Herrera led three bootcamp participants through pouring brass from the crucible into medallion molds lined up on the grated foundry floor. They moved as a team, with one participant at each end of the two-person crucible shank. The other participant and Herrera stayed close to each end as backups. De Cicco guided the effort from the center, directing the team from pour to pour.
They poured silicon brass, a mix of copper, zinc and about 4% silicon, into molds that would produce four medallions each. About a half hour later, the group broke the cooled castings out of the sand molds and discussed the results with the instructors.
