Nikkoshi's "OGF treatment" is an oxidation coating process for non-porous, crack-free aluminum substrates. By performing OGF treatment, the gas released from the surface when heated to temperatures between 50 and 400°C is nearly the same as that of pure aluminum, and no cracks occur in the oxidation coating even near 450°C. By creating an OGF-treated coating on the inside of vacuum equipment, such as vacuum piping, it helps suppress outgassing and speeds up the vacuum process. 【Features】 ■ Reduces outgassing from metals ■ Increases the speed of achieving vacuum due to outgassing suppression ■ Superior corrosion resistance compared to anodizing *For more details, please refer to the catalog or feel free to contact us.

"Joining (brazing)" is a technology that allows for the joining of both similar and dissimilar metals by placing a metal with a lower melting point than the base metals in between them, facilitating the joining through atomic diffusion. Since the joining occurs at a temperature lower than the melting point of the base metals, there is less thermal impact. Additionally, complex structures with good airtightness can be joined simultaneously. 【Features of the Manifold Manufacturing Method】 ○ Processing Setup → Monolithic Type (Current): Requires cutting in two or more directions (vertical, horizontal, etc.) → Separated Type (Joining): Easier processing due to unidirectional cutting. ○ Cutting Amount → Monolithic Type (Current): Requires processing from the side, creating dead space. → Separated Type (Joining): Allows for manufacturing with only the necessary flow paths processed. ○ Flow Path Shape → Monolithic Type (Current): Results in a linear shape. → Separated Type (Joining): Flow path position and shape can be freely designed.
