It is possible to produce metal foil with a surface roughness at the single nanometer level in the form of a hoop-shaped roll extending up to 100 meters.
We perform mirror finishing on various metal foils (such as SUS304, copper, aluminum, brass, nickel, molybdenum, tungsten foil, etc.) using our unique wrapping processing technology. We have independently developed an automatic mirror finishing device that continuously supplies, polishes, and rolls up long tape-like metal foils. In addition to long strips, we also accept mirror polishing of metal foils in desired shapes (from a thickness of 0.001mm). For long strips, we can accommodate thicknesses starting from 0.01mm (depending on the material) and sizes up to 300mm (based on past performance). 【Supported Materials】 SUS304, copper, aluminum, brass, nickel, molybdenum, tungsten foil, etc., with plans for gradual expansion.

Company information
We specialize particularly in ultra-precision mirror surface processing, with a maximum size capability of φ1500 for single-sided machines. We excel in improving flatness, parallelism, and surface roughness for precision stages and suction plates. For suction plates around φ300*10t, we produce with flatness of 0.001, parallelism of 0.001, and Ra below 0.01 (for SUS material). For φ100*5t (materials such as SUS, Ni, Ti, Mo, Ta, W, ceramics, Si, etc.), we can manufacture plates with precision of less than 0.001 in flatness and around Ra 0.001, which are used as ultra-high precision jigs and molds. ◆ Selected as one of the 300 vibrant small and medium-sized manufacturing companies in 2007. ◆ ◆ Chosen as one of the "Global Niche Top 100 Companies" by the Ministry of Economy, Trade and Industry in 2014. ◆ Selected as a "Regional Future Leading Company" by the Ministry of Economy, Trade and Industry in 2018.
