This technology is a precision rolling process that improves strength and creates a good surface by applying cold rolling, which our company specializes in, to materials that have been softened through heat treatment. Various metals undergo heat treatments such as annealing, solution treatment, and aging treatment in-house during the rolling process as needed. Additionally, our staff, who inherit the technology cultivated over many years in titanium foil spacers, produces materials with a thickness accuracy of ±2% or less. This processing technology is adopted for reference plates of measuring instruments, and we meet the requirements for special tolerance products with a thickness accuracy of 1% for beryllium copper alloys and pure iron. *For more details, please download the PDF or feel free to contact us.
