• Mechanical Design

Oil was discovered in Nagaoka during the Meiji era. The demand for the manufacturing and repair of mining machinery that accompanied this led to the development of the machinery industry in Nagaoka. Pretech N Co., Ltd. was established in 1916 (Taisho 5) as Nagai Iron Works, following this trend. Since then, we have expanded our scope to include the manufacturing of precision machine parts, as well as the design and assembly of industrial machinery, starting with metal processing. Throughout our 100-year journey, we have continuously refined our technology and improved our quality control system. Utilizing these strengths, we will always embrace challenges and continue to move forward step by step for the benefit of our customers and the community. 【Features of Pretech N】 ○ High processing technology ○ Integrated production system ○ Reliable delivery response For more details, please contact us or download our catalog.
