basic information
【Other Features】 <Internal Structure of the Roll> ■ It is possible to maintain a constant temperature by creating internal channels to pass water or oil through the surface of the roll heated by melted resin. <Surface Finish / Ultra Mirror Finish (Ry0.05s or less)> ■ Ultra mirror rolls are essential for high-performance film manufacturing. ■ The surface of the roll after hard chrome plating can be finished to Ry0.05s or less. <Surface Finish / Satin Finish> ■ Satin finish enhances the release properties of the film. ■ A surface treatment method that creates fine unevenness by sandblasting the surface of the roll. ■ To improve release properties when very thin films pass through the roll in the device, there is a specification to finish the surface with a satin finish. ■ There are both pre-satin and post-satin treatments, which are differentiated based on the application. <Surface Finish / Embossing and Engraving> ■ Engraving is applied to the surface for purposes such as ink transport and precise glue supply, which are essential in the printing machine industry. ■ Various engraving processes are supported through collaboration with partner companies. *For more details, please refer to the PDF document or feel free to contact us.
