Zirconia ceramic knife ring

  • Finished product characteristics

    ● High hardness, high toughness, high bending strength ● High wear resistance, low friction coefficient, ● strong corrosion resistance ● Low thermal expansion coefficient ● Good insulation ● Long life ● High temperature resistance

  • Product characteristics

    High processing precision, special ceramic formula, quality assurance, cutting edge width less than 0.1mm, diameter specifications from 30mm to 260mm complete, can be customized. Easy to clean, save ink, long-term use of the ring mouth is still bright and dense, good sealing performance, effectively prevent ink leakage.

  • Precision machining

    1. 3Y, 5Y, 8Ymol yttrium stabilized zirconia zirconia powder

    2. Open mold processing: dry pressing, CIM injection molding, isostatic pressing.

    3. Appearance processing: surface grinding, outer diameter/inner diameter grinding, fine engraving machining, grinding, polishing grinding.

  • Application field

    ● Automotive, electronics, toys and other printing workshops, supporting the corresponding size of the oil cup printing machine
