Latest Patents

Nishizaki holds a patent for a process for producing hollow aluminum extrudates for use in a vacuum. This process involves hermetically closing the forward open end of a hollow shaped material immediately after extrusion. Subsequently, a predetermined length of shaped material is extruded, cut off, and hermetically closed at the cut end. This method ensures that the inner surface of the hollow portion remains out of contact with the atmosphere, which inhibits the formation of hydrous oxide while allowing for the creation of a compact oxide film.
