Neosho Trompler

Neosho Trompler is an established family-run precision machine shop based in Hartland, Wisconsin since its founding in 1967 by Lorant and Margit Trompler. The company specializes in high-quality custom machined parts for diverse industries including hydraulics/fluid power (with subsidiary manufacturing hydraulic pumps/cylinders), construction equipment, agriculture machinery components, defense applications and more. With over six decades of experience and significant investment in modern equipment—including more than sixty-five advanced CNC machines—the firm delivers both prototype development and high-volume production runs from its ISO-certified facility. While it has no direct involvement or product pipeline within the life sciences/biotech/pharma/healthcare sectors—and thus does not work with therapeutic modalities or targets—it remains a key supplier to American industry through its focus on quality engineering solutions.
