6.Factory price offer

7.We offer you after sales service .


Corrugated Slitting Knives are consistently produced to the highest ISO9001:2015 standards . There are over 4 steps

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.


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.





Q1. How do you control the quality ?

First control is 100% raw material from WC supplier, 100% inspecting throughout each process.

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


Q8.How about the delivery ?

If you order in the hot sale season,delivery time will be over 1 month .normally ,some size we keep small stocks ,mostly will need take 3-4 weeks to finishe products
