Shen Gong Carbide Knives' PVD-coated corrugated slitter scorer knives redefine durability and precision in cardboard processing. Designed for demanding high-speed lines (up to 450m/min), our HV3200-hardened blades cut downtime significantly and slash blade replacement costs with a longer lifespan advantage over traditional knife. Trusted by premier packaging groups, these ISO 9001-certified knives deliver highly precise accuracy across all flute types (A/B/C/E), ensuring smoother operations and higher OEE.
Our slitter scorer knives are coated with PVD (Physical Vapor Deposition) technology, featuring TiN or TiCN coatings that offer superior hardness and wear resistance. This advanced coating ensures that the blades perform reliably even in high-speed production settings. The surface hardness of our knives reaches HV3200 (HRA 91.7). With a nano-thin coating thickness of 0.3-3μm, our knives maintain sharp cutting precision throughout their long service life, ensuring consistent performance without frequent re-sharpening. These PVD-coated corrugated slitter scorer knives are suitable for use with a variety of corrugated board types, including 120–600gsm (A/B/C/E flute optimized).

Applications & Performance
A major packaging group faced challenges with frequent downtime and blade wear in their high-speed corrugated production line (450 meters/min). The need for frequent blade replacements was increasing operational costs and production stoppages. By switching to our PVD-coated slitter scorer knives with TiN/TiCN coating, the group achieved a significant increase in hardness (HRA91.7) and wear resistance. This upgrade resulted in smoother slits, reduced downtime, and a 20% increase in production efficiency.

Frequently Asked Questions
Q1: What is the benefit of PVD coating on slitter knives?A: PVD coatings like TiN and TiCN significantly increase surface hardness and reduce friction, leading to longer tool life and cleaner cuts.
Q2: How hard are these corrugated slitter knives?A: Our knives reach a surface hardness of HV3200 (approximately HRA 91.7), providing exceptional durability.
Q3: What types of corrugated boards can these knives cut?A: They are optimized for 120–600gsm corrugated boards, including A, B, C, and E flutes.
Q4: Can these blades operate in high-speed production lines?A: Yes, they are designed to perform reliably in lines operating at speeds up to 450 meters per minute.
Q5: What is the waste rate when using these knives?A: Due to the 40% lower friction, the waste rate is typically maintained at ≤0.8%.
Q6: How thick is the PVD coating layer?A: The nano-thin coating ranges from 0.3 to 3μm, ensuring the blade remains sharp without compromising precision.
