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.

● To determine the sealing and waterproofing of sealed products based on pressure changes, it is not necessary to conduct tests that involve spraying water on the product or immersing it in water. ● Once the product is placed in a dedicated fixture within the inspection device, waterproofing can be quantitatively confirmed through automatic measurement. ● The target product size is W 300 × D 210 × H 100 mm or smaller. ● The target products include automotive cameras, smartphones, ECUs, small motors, and other packaging containers, and are effective for any products that require confirmation of sealing, waterproofing, and airtightness. ● For product specifications and details, please contact us.

In battery manufacturing lines, if components containing copper are used, there is a possibility that metal powder may mix in, dissolve, ionize, and pass through the separator, causing a malfunction that connects the positive and negative electrodes. Such minute metal powders may not be detected during pre-shipment inspections, and even if they are found, they can lead to various issues, such as the need to increase inspection processes to detect them. Therefore, Fukuda has developed a copper-free (all stainless steel) air leak tester that can be safely used in the production lines of battery manufacturers and secondary battery manufacturing equipment manufacturers.
