The types of coatings compatible with Esko Kongsberg blades include:
- C2 Coating: This is a hard, smooth, and durable coating that reduces friction by about 60% compared to standard DLC coatings. It significantly increases the blade's lifespan and efficiency, making it suitable for cutting corrugated board and various other materials. The C2 coating is biocompatible and safe for food, medical, and dental industry use.
- TiN (Titanium Nitride) Coating: This coating is used on some rotary blades for improved hardness and wear resistance, suitable for cutting tough materials like aramid fibers, carbon fibers, felt, and various textiles.
- Carbide Blades: Though not a coating but a blade material, tungsten carbide blades provide long life and durability for tougher materials and are often paired with coatings for enhanced performance on Esko Kongsberg machines.
The Esko Kongsberg C2-coated knife blades (BLD-SF216 C2, BLD-SR8184 C2, BLD-SR8174 C2, BLD-SR8170 C2, BLD-DR6160 C2, BLD-SR6150 C2, BLD-DR8160 C2, BLD-SR8172 C2, BLD-SR8124 C2, BLD-SR8180 C2) utilize a tungsten carbide C2 coating to significantly enhance blade performance and longevity.
Key blade coating features:
- Tungsten carbide C2 coating:Provides a super-hard, low-friction surface that increases blade life by up to six times compared to uncoated blades.
- Reduced friction: The coating minimizes lift and pull during cutting, requires less power, and reduces energy consumption.
- Wear resistance: The blades maintain sharpness longer when cutting abrasive materials like corrugated board, folding carton, plastics, and foam.
- Environmental safety: The C2 coating is biocompatible and environmentally harmless.
Typical applications for these coated blades include:
- Corrugated cardboard (single/double wall, microflute)
- Folding carton
- Foamed PVC / PS (Forex, Sintra)
- Corrugated plastics and display board
- Flexible magnetic foil, paper, and adhesive vinyl
Many blades in this group feature a round shank (Ø 8 mm) and cutting angles from 30° to 40°, with maximum cutting thickness up to 4.5 mm.
Summary:
If you need Esko Kongsberg blades for high-frequency production or demanding substrates, the C2 (tungsten carbide) coating offers substantially longer life, less downtime, and better cut quality. This choice is especially advantageous for corrugated packing, display production, and mixed media cutting where blade wear rates are high.
