The Scania foundry in Sweden is producing compacted graphite iron cylinder blocks and cylinder heads for the new Traton Group 13-liter diesel engine, under its SinterCast AB license. The group, which manufactures trucks and buses under the Scania, MAN, International, and Volkswagen Truck brands, recently launched production of the new engines at its MAN engine plant in Nuremburg, Germany.
CGI is a lightweight cast iron that offers greater tensile strength, stiffness, and fatigue strength than gray iron or aluminum. SinterCast offers the most widely used process technology for CGI production, mainly by foundries supplying engine blocks and cylinder heads to diesel and gas engine manufacturers.
The Scania foundry at Södertälje, southwest of Stockholm, is a major producer of CGI according to the SinterCast control process.
MAN reported it will be producing approximately 50,000 of the new engines per year. SinterCast added that number corresponds to more than 400,000 “engine equivalents” of CGI per year (20,000 metric tons), meaning an increase of more than 12.5% above the current SinterCast run-rate of approximately 3.2 million engine equivalents/year (16,000 metric tons/year.)
“The start of production at MAN marks another important step in our journey with the Traton Group. The first step began in January 2019 when we received the order to install our technology in the new Scania foundry in Sweden. Following the construction of the purpose-built foundry, we began production for Scania applications in 2022 and for International (Navistar) applications in 2023. We now welcome the start of production at MAN,” according to SinterCast president and CEO Dr Steve Dawson.“
In addition to the Scania foundry, Traton 13 liter cylinder blocks and heads are exclusively produced using the SinterCast technology, at the Tupy foundries in Brazil and Mexico.
