The Graham Group on Monday announced that it acquired American Kuhne, a Rhode Island-based manufacturer of extruders, extrusion systems and screws.

York-based Graham, an engineering firm, was attracted to American Kuhne's position in the medical extrusion market and dedicated customer service, according to Dave Yenor, vice president of global business development for Graham.

"Bringing American Kuhne into the equation now enables the Graham Group to immediately diversify our market presence into the medical industry," he said.
