Frequently Asked Questions
For metal-foil composite or insulation paper, we strongly recommend Cemented Carbide (Tungsten Carbide) blades with hardness HRA 89+, as they offer the extreme wear resistance required for these abrasive materials.
Straight knives are cost-effective for low-confidentiality office paper. Sawtooth knives are designed for high-toughness materials like laminated paper and cardboard, offering lower cutting resistance.
Titanium Nitride (TiN) coating reduces the friction coefficient by 35%, which significantly decreases paper scrap adhesion and extends the interval between sharpenings.
Yes, we utilize advanced laser cladding technology to repair worn edges, which can restore the service life of the blade to approximately 80% of a new product.
Spiral blades are optimized for high-efficiency continuous operations. Claw knives (3/8/12 claws) are specifically designed for heavy-duty impact against hard cardboard and multi-layer corrugated boxes.
Since stainless steel has lower hardness, it requires more frequent edge checks and the use of paraffin lubrication to prevent rust and maintain cutting efficiency during intermittent use.
