Navistar’s PurePower Launches CGI Program PurePower Technologies LLC, a


Navistar company, recently started production of compacted graphite iron (CGI) cylinder blocks at its Indianapolis casting facility. PurePower has licensed CGI


process control technology from SinterCast, Stockholm, Sweden, for use at its casting facilities in Indianapolis and Waukesha, Wis. The company has not yet launched a CGI program on its two casting lines in Waukesha. PurePower expects the new


capability to allow it to produce high- volume CGI castings for passenger vehicle applications and commercial vehicle cylinder blocks and heads with engine displacements as large as 15 L. “Building on more than 10 years


of CGI product development and production experience within Navistar, PurePower has the experience, facilities and team to be a world- class provider of high quality CGI engine components to the passenger vehicle and commercial vehicle industries,” said Rick Bacon, director of PurePower’s metalcasting division. “We have brought the Indianapolis casting facility on-stream in record time to meet the increased demand for heavy-duty CGI blocks.” Founded in 2009 by Navistar, PurePower produces diesel power

ME Elecmetal, Santiago, Chile, announced it will spend $12.2 million on an expansion at its metalcasting facility in Duluth, Minn., less than a year after completing a previous improvement at the facility. According to Bill Grau, Duluth plant manager, ME Elecmetal will add a third arc furnace and additional heat treating capacity to keep pace with the molding capacity increases resulting from last year’s expansion. T e investment is expected to yield a 30% melting capacity increase to 160 metric tons per day.

phases,” Grau said. “Last year, [we did] a $10 million expansion to eliminate bottlenecks, create more space, improve fl ow and lower our [work in process]. We had additional mold line capacity, but we couldn’t make any more metal. Everything we added last year was done with this in mind.” In 2011, ME Elecmetal spent
