SinterCast AB reported a strong rise in compacted graphite iron series production during Q2 2025, up 10% from the first-quarter volume to 3.4 million engine equivalents, or 170,000 metric tons. Compared with the second-quarter of 2024, the new result showed a -15% decrease thanks to stoppage at one high-volume engine program and the broader effects of reduced commercial-vehicle demand in Europe and North America during that period.
Compacted graphite iron (CGI) is a lightweight material that offers greater tensile strength, stiffness, and fatigue strength than gray iron or aluminum. As such it is gaining acceptance for diesel engines, for commercial vehicles and industrial systems.
Stockholm-based SinterCast’s CGI process control technology is used by foundries worldwide for series production of engine castings.
The second quarter of this year included a new SinterCast installation at the Saroj Foundry, in India, and the third quarter has already brought firm orders from foundries in Brazil (Maringa Soldas) and China (Xu Ruifeng.) Those installations will proceed during the summer, according to SinterCast, and discussions toward other installation are ongoing.
“One year ago, we posted our thirteenth consecutive quarter of year-on-year quarterly growth. Now, with the increased volume in the second quarter, we start to see the onset of the recovery,” stated SinterCast president and CEO Dr. Steve Dawson.
“In the near-term, we look forward to beginning a new string of consecutive quarterly increases before year-end,” he added.
In line with the Q2 production increase, sales of SinterCast sampling cups for CGI production totaled 58,050 units for the April-June period, and rose to 103,950 units for the first half of 2025.
“The highlight of the second quarter was the announcement of three new commercial vehicle programs with combined volume of more than 500,000 engine equivalents (25,000 metric tons) per year,” Dawson stated. “Together with the programs that are already in the ramp phase, these new programs provide the building blocks for reaching the 5 million and 6 million engine equivalent milestones.
The announcements also validate our longstanding confidence that all commercial vehicle OEMs will adopt compacted graphite iron before the end of this decade,” he concluded.
