GE Aviation and SeaCast have established a 50/50 joint venture (JV) called Montana Precision Products which will produce engine components at SeaCast’s facility in Butte, Montana. SeaCast is headquartered in Marysville, Washington, and produces castings and speciality components; the JV will produce tubes, ducts and small structural castings for GE engines. SeaCast’s Butte operation has supplied GE Aviation for several years, producing parts for engines such as the GE90 and GEnx high-thrust models for large commercial aircraft. Both GE and Butte will invest in the Butte facility in order to handle the higher volume, with the workforce expected to grow over the next four years from its current strength of 70 individuals. Colleen Athans, VP and GM, supply chain division, GE Aviation, said that the Butte operation offers “critical skills in welding and fabrication”, adding that the new partnership will bring “much needed additional capacity”.
