A diversity of wire coiling techniques that gives rise to highly sophisticated filaments.
Mitsuwa's wire coiling technology responds to a wide variety of configurations, including continuous coiling, variable pitch coiling, and double coiling, etc. It can coil an ultra-fine wire to high precision and support characteristics problems including selection of properties, shape, and material of the filament.

    100% -240% | 
| MD/WD ratio | 170% *2 | 140% *3 | 270% *2 | 
* Send separate inquiries about dimensions.
*1 Coil pitch: Ratio of distance between wire diameters to wire diameter; values in the table are recommendations.
  *2 MD/WD ratio: Ratio of core wire diameter to wire diameter; that for double coiling is the value for the primary coiling.
