SG PVD Coated Tungsten Carbide Slitter Scorer Knife | Anti-Stick and Chip-Free for Corrugated Cardboard

Short Description:

Shen Gong PVD coated tungsten carbide slitter scorer knives are engineered to elevate performance for corrugated cardboard processing. Hardened to HV3200, these blades operate reliably on high-speed production lines with a running speed up to 450 meters per minute.
Compared with conventional tools, they deliver far longer service life, effectively cutting downtime and reducing blade replacement expenses. Manufactured under strict ISO 9001 standards, the knives maintain excellent precision when working with A, B, C and E flute corrugated board. Featuring reliable anti-stick and chip-free cutting performance, they help streamline production and raise overall equipment effectiveness (OEE). These blades have gained wide recognition from leading packaging enterprises.

Detail Descrption

Shen Gong 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.Shen Gong Carbide Knives' PVD-coated corrugated slitter scorer knives is suitable for use with a variety of corrugated board types, including 120–600gsm (A/B/C/E flute optimized).

Applications

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 Shen Gong’s 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.
