Montana Precision Products

View

Montana Precision Products (MPP) manufactures high-precision aerospace and commercial components in Butte, Montana, including tube and duct assemblies, small structural castings, and flex joints. It uses investment casting (lost-wax) to create complex metal parts by building a ceramic shell around a wax pattern and pouring molten metal, resulting in parts that handle heat and vibrations. The company differentiates itself through its GE Aerospace–SeaCast joint-venture heritage, AS9100 certification, and ongoing capacity investments such as a 2022 expansion and 2025 modernization funded by GE Aerospace. Its goal is to reliably supply the aerospace supply chain with complex, quality parts and to expand manufacturing capabilities to meet rising demand.

Simplify's Take

What believers are saying

  • GE Aerospace announced a $2 million Butte investment on April 23, 2025.
  • Montana’s September 5, 2025 visit confirmed capacity modernization and plans for 60 hires.
  • MPP’s nearly 100,000-square-foot plant supports narrowbody, widebody, and military engine demand growth.

What critics are saying

  • GE Aerospace still controls demand; a single-program shift can compress MPP volumes quickly.
  • MPP faced an NLRB retaliation case filed January 29, 2025, signaling labor-management friction.
  • If GE Aerospace insources or redesigns engine hardware, MPP loses its anchor customer and financing.

What makes Montana Precision Products unique

  • Since 2012, MPP has been a 50/50 GE Aerospace and SeaCast joint venture in Butte.
  • MPP makes AS9100D-certified tube, duct, and structural castings for engines and military marine systems.
  • Its 2022 expansion added 56,000 square feet and launched flex joints manufacturing.
