Product Description


Tungsten carbide circular slitter blades corrugated paper cutting round knives

Hardness: If hardness is high, when the blades meet higher tensile strength steel, it is easy to crack.If the hardness is low,then the wear resistance is not good, that means work life is shorter.


Features and Benefits

  • Lower yearly knife consumption costs.
  • Strictly quality control for excellent valve.
  • High precision, high intensity.
  • Excellent hardness,small thermal deformation.
  • Matched to their applications.
  • Reduce unsurpassed edge quality.
  • Reward customers with high Productivity.
  • Increased blade lifetime and reduced retooling time.
  • Excellent cutting quality,stable and reliable cutting performance.

Key Performance Indicator

  • Suite material selection.
  • Good price and offering.
  • Advance cutting technology.
  • Production cost optimized.
  • Stock & Inventory efficiency.

Before using knives

  • Check the existing package.
  • Check the number , specification , operation and trouble-shooting.
  • Understanding of our technical & products.



  • Paper industry
  • Printing industry
  • Metal industry
  • Textile industry

Tungsten carbide blade is mainly used for cutting paper in printing industry
tungsten carbide knife products require high precision, no glitches, maximum abrasion resistance.
we are using HIP sintered and fine grinding, polishing plating to reduce frictions when cutting, improved the accuracy and speed slitting greatly, tool life extended .

tungsten carbide circular slitter blades corrugated paper cutting round knives


Corrugator slitter blade is made of ultra-fine tungsten carbide powder and cobalt powder pressed into sintering, is the best choice for cutting corrugated cardboard (3/5/7 layer) in the carton manufacturing industry. Ultra-specular (maximum surface roughness of .025μm) prevents film build-up on the blade for cleaner, more precise cuts.

Corrugated Slitting Knife can be accepted to work in harsh environments, so that product strength is greatly improved should not be damaged when used, the high-precision m-class special equipment production and processing, to ensure that the flatness of the product reached the slitting board does not fall edge shape, meet All kinds of cardboard cutting requirements.




As a long standing partner to the Corrugated Industry ,zhuzhou mingri cemented carbide co. ltd ,manufactures Corrugated Slitting Knives for word renowned primary Corrugated Processing machines such as Agnati, BHS, Fosber, Gopfert, Isowa, Marquip, Mitsibishi, Peters, TCY, Xiexu, LMC, K & Machinery .



Q1. How do you control the quality ?

First control is 100% raw material from WC supplier, 100% inspecting throughout each process.
Continuous training for experienced engineers and workers.

Q2. How can I choose the right TC Grade for the carbide products ?

If you can not confirm which TC grade is right for your products, please kindly provide us with your purpose of usage, we would suggest the most suitalbe grade for you.

Q3. Why the short working life time of corrugated board knives ?

1.Is the grain size of the grinding wheel proper? Too coarse grain size of grind wheel :make a short working life time of knives.
2.Too frequent grinding; the grinding time is too long, or the grinding pressure is too high.

Q4. Why the edge of corrugated boards cut by knives with burr and dent ?

1.Please check the cutting edge of your blades. Is the cutting edge keen enough?
2.The corrugated board is too wet.

Q5. Why the knife break ?

1.Improper assembly(e.g. deformed flange plate; improper screwing)will cause the quick break of blades. Any improper touch of the blades is strictly prohibited during the working.
2.Unstable swing grinding wheels break the knives, please check the bearing of grinding wheels.
3.Improper touch or strike with other hard things.
4.Accident collision of knives

Q6. Why chips on the cutting edge after the grinding ?

1.Unstable swing grinding wheels may cause this problem, even break the knives.
2.The strike of hard things may cause the chips on the cutting edge.

Q7. Why the edge of corrugated board is not straight.

Unmatched strength of the knives for the corrugated board with high density.


About packing 


1 we will make sure that your tungsten carbide disc cutter clean before package.
2 rubber strip wrap sharp cutting edge to avoid edge broken.
3 put into plastic bag and styrofoam box to keep tungsten carbide disc cutter steady when express deliver
4 add plastic foam into inner box for the whole tungsten carbide disc cutter for sweet protection.
5 we will make export standard strong cartonn or plywood case package according to your needs.
