An innovative cooling system is speeding production on a Stellantis hot stamping line for Jeep, Fiat, and Alfa Romeo models in Cassino, Italy. AP&T installed the press hardening line in 2007 but has upgraded it with improved cooling under a 2019 preventative maintenance deal and the change is letting the company crank out models like the Jeep Renegade faster than ever.
“It has meant substantially reduced cycle times, making it possible to form more parts in a shorter amount of time,” explained, Stellantis’ Cassino Press Shop Operational Manager, Cesare Zeppieri.
Precise control over localized heating and cooling of the tools using AP&T’s TemperBox technology lets the plant stamp pieces with both hard and soft zones at the same time, he reported. “AP&T's in-line process monitoring provides full control over heating and cooling by using infrared camera technology and a pyrometer, making it easier to ensure that each part lives up to the quality requirements.”
This precision control is possible not only with new tooling in the plant but also with existing machines. “All new tools brought into use, and many existing tools, utilize this type of cooling,” said Zeppieri. “Another solution we find highly interesting and are looking into is AP&T's in-line process monitoring.”
