Roll Shaft

We manufacture various roll shafts indispensable to various facilities that support the information industry, and contribute in each field.

"Roll & roll", various products invented from combination of this simple materials. We pursue a system of the production control that can correspond to any type of needs every day.

We are very proud to introduce our accruate and advanced quality with stable finishing that can correspond to the demand regarding ' From the material to heat treatment ', ' Machine work ', ' Grinding ', ' Industrial chromium plating ' and ' The roll mirror finish '.

Here, we explain the "internal structure" and "surface finish" that are important for making jacket rolls with a multi-tube structure.

We also explain the "flow of roll production", so we hope you will get to know the world of jacket rolls as much as possible.

By creating a flow path inside and letting water or oil pass through, the surface of the roll heated with the melted resin can be kept at a constant temperature.

The pattern of the flow path varies depending on the mechanical specifications and the type of resin to be flowed, and even the spiral specification has 2, 3, and 4 threads, and there is also a path method in which the flow path flows in the longitudinal direction.

It is a mirror surface roll that is indispensable for producing high-performance film. The surface degree also varies. In recent years, there have been many requests for the production of ultra-mirror surfaces, and there are increasing calls for high quality films in the market.

Seimitsu Industrial Co., Ltd. can finish the roll surface after hard chrome plating to Ry0.05s or less.

Satin Finish is a surface treatment method that creates fine irregularities by sandblasting the surface of the roll.

There is a specification to finish the surface to Satin in order to improve the releasability when a very thin film passes through the roll in the device.

Satin has pre-satin treatment and post-satin treatment, and the treatment is selected according to the place of use.

The surface is engraved for the purpose of transporting ink and supplying a fixed amount of glue, which are indispensable in the printing press industry.

We support various engraving processes in cooperation with partner companies.
