In the printing industry, engraving is essential for purposes such as ink transport and precise glue supply on the surface. Additionally, engraving may be required when seeking the release properties of films.

• Other processing machines

A pearlescent (satin) finish refers to a surface treatment method that creates fine unevenness on the surface of a roll by sandblasting it. To enhance the release properties when a very thin film passes through the roll in the device, there is a specification to finish the surface with a pearlescent (satin) texture. There are both pre-satin and post-satin treatments, and the choice of treatment depends on the application.

• Other processing machines

When producing high-performance films, the mirror rolls, which are indispensable, come in various surface roughness levels. In recent years, there has been an increase in requests for ultra-mirror finishes, and the demand for high quality in films in the market has been rising.

• Other processing machines

The surface of the heated roll, which is melted by resin, can maintain a constant temperature by creating internal channels to allow water or oil to flow through.

"Friction welding" is a welding method that generates friction heat as a heat source by applying pressure to metal contacts while causing relative motion. Our company recognized the advantages of this friction welding early on and has utilized it in our products, as well as widely accepting processing requests from everyone, contributing to cost reduction and quality improvement. Currently, we are equipped with five automatic friction pressure welding machines and are accepting contract processing. [Features] ■ The mechanical strength of the joints is extremely high ■ Does not require welding rods or solvents, and does not need special groove processing ■ High energy efficiency ■ Capable of joining dissimilar metals ■ Material savings and reduction of man-hours are possible *For more details, please refer to the catalog or feel free to contact us.
