  • High concentricity is achieved for ultra-fine nozzles with internal diameters from 0.1 mm
  • High strength and high precision processing of thin-walled pipes
  • Small surface roughness of the inner diameter (from Ra 0.1 μm) suppresses unnecessary component residue during repeated use (suppresses carryover).
  • Outstanding wear and chemical resistance lowers replacement frequency.

Surface Smoothness

* Zirconia has small crystal grains and less voids, so chipping is unlikely and the surface is incredibly smooth.
