Narit Therdsteerasukdi, Secretary General of the Board of Investment (BOI), said the new facility operated by NMB-Minebea Thai Ltd received BOI investment promotion approval to produce high-precision aircraft components. The factory will manufacture flight propulsion system parts including Ball, Race Bush and Spherical Bearing components, as well as aircraft structural and fastening parts such as Bolt, Sleeve and Fitting products.
The new building covers 16,500 square metres and is equipped with high-precision machinery and automation systems. The investment forms part of MinibeaMitsumi’s long-term expansion in Thailand, where the Japanese group first invested in 1982 through the production of miniature ball bearings.
Over the past four decades, NMB-Minebea Thai has expanded into electronics components, medical equipment parts, machinery, electrical appliances, automotive parts and aerospace components. The company has received BOI promotion for 65 projects with a combined investment value exceeding Bt115 billion.
The company currently employs more than 31,000 Thai workers and operates 10 factories across five provinces: Ayutthaya, Pathum Thani, Lopburi, Chonburi and Rayong. Thailand is also home to the group’s largest miniature ball bearing production base in the world, supplying markets including Japan, Singapore, China, the United States and Europe.
NMB-Minebea Thai began producing aerospace components in Thailand in 2003 and has spent more than 20 years developing high-precision technology and quality control systems to meet aviation industry standards. The company has secured certification from both Airbus and Boeing and has supplied components into the global aerospace supply chain for more than two decades.
Narit said the latest investment is not simply a factory expansion but an upgrade of Thailand’s role as a Global Core Factory for MinibeaMitsumi’s aviation business. The company is also establishing a research and development centre in Ayutthaya to support advanced technology development and strengthen long-term competitiveness.
President, COO and CFO Katsuhiko Yoshida said Thailand had demonstrated its ability to serve as a world-class aerospace manufacturing base. He noted that while labour shortages continue to affect aerospace supply chains in other countries, Thailand has maintained stable production, giving it a significant competitive advantage.
ThaiRath reported that Yoshida added that MinibeaMitsumi remains committed to keeping Thailand as one of its key manufacturing bases and plans to continue expanding investment in the country to help support sustainable economic growth.
