Montana Precision Products (MPP) is a specialized manufacturer focused on the aerospace and commercial sectors, operating from its facility in Butte, Montana. The company was established in 2012 as a 50/50 joint venture between GE Aviation (now GE Aerospace) and SeaCast, Inc., a casting and specialty components producer. This strategic partnership was formed to enhance GE Aviation's supply chain capabilities as its jet engine production rates increased, building upon a multi-year supplier relationship where SeaCast's Butte operation produced components for GE's GE90 and GEnx engines.
The business is a key supplier of complex, high-precision components. Its product portfolio includes tube and duct assemblies, small structural castings, and flex joints. These parts are critical for various aircraft engines and systems, designed to handle thermal expansion and vibrations. The company serves the demanding requirements of the aerospace industry by manufacturing components for both narrowbody and widebody aircraft engines, as well as for military marine engines. MPP utilizes an investment casting process, also known as the lost wax process, which involves creating a ceramic shell around a wax pattern to form a mold for molten metal, enabling the production of intricate and durable parts.
Significant milestones for the company include a major facility expansion in 2022, which added 56,000 square feet to reach a total of 97,000 square feet of manufacturing space. This expansion not only increased capacity for existing product lines but also facilitated the launch of a new line for flex joints. The company has received continued investment from its parent companies, including a $2 million investment from GE Aerospace in March 2025 to modernize the facility's layout and improve workflow. While specific founders of the joint venture are not named, the partnership was built on the existing business of SeaCast, which was owned by Butte natives and brothers Bert and Mike Robins.
