Corrugated Knives
Tungsten Carbide Slitter Blade for Corrugated Board Lines | No Edge Crushing
Core Advantages
Precesion Edge Profil - Zero Edge Crushing
Self-Developed Submicron Carbide - Extened Service Life
Our in-house submicron tungsten carbide maintains a sharp, consistent edge profile for much longer. It keeps delivering crush-free cutts even during extended high-speed production runs. The material balances hardness and toughness perfectly. It offers significantly better wear resistance than standard carbide grades and cuts down on downtime needed for blade changes.
20+ Years Mature Production – Stable Quality, Competitive Price
We have refined corrugated blade edge geometries for over 20 years. Our mature, scaled production line delivers consistent edge precision across every batch. We also deliver solid cost efficiency through scaled manufacturing. You will get premium cutting performance at a lower total cost of ownership.
Quality Assurance
•ISO-Certified Production Control
Designed for continuous cutting of abrasive steel wire reinforced rubber materials. All manufacturing follows ISO9001 quality standards. From powder formulation to final grinding, every step follows standardized protocols to eliminate batch-to-batch variations.
•End-to-End Batch Tracebility
Every batch of raw materials is tracked through the full production chain – powder mixing, sintering, grinding and inspection. We retain samples for 3 years for full tracebility.
•Pre-Shipment Cutting Performance Test
Beyond dimensional checks, every blade passes a simulated cutting test before shipping. We verify zero flute crushing and burr-free edges to ensure it works right out of the box.
