Ognas Sornas Q&A Corner

■Coating for Inner Diameter - Coating cannot be applied to inner diameters of 10 mm or less. - For diameters larger than this, the basic depth will be twice the inner diameter; please consult us each time. ■Maximum and Minimum Usable Sizes - Coating can be applied to a maximum roll or plate size of approximately 2m in height, 2m in width, and 9m in depth. - Coating is also possible for small items, such as those the size of a palm. ■Regarding Recoating - It is possible to remove the existing film by blasting and reapply the coating; coating over films from other companies is also possible (consultation required). - Partial recoating or repairs are not possible. All existing films must be removed before recoating. ■Applicable Materials - Coating can be applied to common metals such as SS, SUS, and AL. - Due to the blasting and firing processes, coating cannot be applied to materials like resin or rubber (some exceptions may apply). ■Finish Precision of Coating Thickness - As it is spray coating, uniform thickness cannot be achieved, and variations within the standard thickness range will occur. - The finish will be as formed, so dimensional tolerance finishing through mechanical polishing after film formation is generally not possible. Since the thickness may vary depending on the shape of the processed item, please consult us if precision is required.
