Blackpearlnite ブラシクパールナイト


  • Shocking Mold & Die material spending in month end?
  • O. E. E. couldn't achieve due to 6 Big Losses?
  • Spending in tooling doesn't bring significant return?
  • Troublesome in Mold & Die inventory management?

ブラシクパールナイト Blackpearlnite vs Nitriding

Revolution in surface finishing which brought us a 10 years leaps in relevant industries. Blackpearlnite consolidate advantages from conventional Nitriding process and Coating (PVD/CVD/TD).

Characteristic included:
  • High Precision, < 2μm changes
  • Lower Coefficient of friction
  • Lower Cost compare to Coating
  • Strong Wear Resistance
  • Erosion & Heat Check Resisance
  • Corrosion Resistance, >400hr S.S.T.
  • High Thermal Resistance
  • Lubricant Free
  • Fatigue Resistance
  • Shorter Delivery Lead Time
  • Wide Range of Application

Investing in ブラシクパールナイト Blackpearlnite and get return:

  • Eliminate 6 BIG LOSSES, achieving world class O.E.E.
  • 70% saving in RAW MATERIAL.
  • Realization of K.P.I. target in short term(1~3 MONTHS).
  • Tooling failure isn't a valid escuse anymore.


  1. Free Release Agent

    Due to its erosion resistance, heat resistence and releasability are higher than ceramic coating, it does not react with molten metal or solid metal. Therefore, it has better heat checking resistance as compared to nitriding treatment.

  2. Low Temperature Treatment

    Due to lower temperature treatment as compared to tool steel’s tempering temperature, there is no deformation or distortion in dimensions.

  3. Uniform Treatment to Complex Shaped Product

    Unlike conventional PVD coating, Blackpearlnite can heat treat various 3-D solid complex shapes with deep holes, narrow slits and therefore it has wide range of applications.

  4. Applicable to Large Scale Prod

    It can heat treat small pin to 1 ton (depends on furnace size)

  5. Low Cost

    Heat treatment cost is relatively cheaper than conventional PVD, CVD and TD method.

  6. Shorter Delivery Leadtime

    Heat treatment cost is relatively cheaper than conventional PVD, CVD and TD method.
