Nilcra Zirconia Boosts Durability in Food Can Manufacturing

In the fast-paced world of food and beverage production, efficiency and reliability are paramount. The introduction of Nilcra® zirconia, a high-performance ceramic material, is transforming can manufacturing by addressing long-standing challenges in mold durability and production downtime.

The Limitations of Traditional Can Manufacturing

Conventional can manufacturing has relied heavily on tungsten steel and tool steel molds. While these materials have served the industry for decades, they present significant drawbacks in today's demanding production environments:

• Rapid wear requiring frequent replacement
• Vulnerability to corrosion from acidic contents
• Increased maintenance costs and production downtime
• Potential for damaging can coatings during forming processes

Nilcra® Zirconia: A Material Breakthrough

This advanced ceramic material offers several key advantages that are reshaping can manufacturing:

• Exceptional Wear Resistance: Outperforms traditional metals by significant margins, extending service life and reducing replacement frequency
• Superior Corrosion Resistance: Maintains structural integrity even in acidic environments common in food processing
• Surface Protection: Ultra-smooth finish preserves can coatings and prevents contamination
• Reduced Friction: Low coefficient of friction decreases energy consumption and heat generation
• Food Safety Compliance: Meets stringent FDA standards for food contact materials

Applications in Can Production

Nilcra® zirconia components are being implemented across various stages of can manufacturing:

• Proseamer™ ceramic seaming rolls for hermetic can closures
• Necking dies for precise diameter control
• Spinning flanging wheels for reinforced edges
• Z-bar tooling for base and end formation
• Double seaming rolls for enhanced seal integrity

Performance Advantages

Beyond its material properties, Nilcra® zirconia delivers measurable operational benefits:

• High strength-to-weight ratio withstands forming pressures
• Exceptional fracture toughness prevents catastrophic failures
• Thermal stability maintains dimensional accuracy
• Customizable geometries accommodate diverse can designs

Industry Adoption and Results

Early adopters report significant improvements in production metrics. A major beverage producer achieved:

• 300% increase in component lifespan
• Reduction in defective seals
• Enhanced production throughput

Similarly, a food canning operation noted marked improvements in surface finish and corrosion resistance when processing acidic contents.

Comparative Advantages

While other ceramics have been tested in can manufacturing, Nilcra® zirconia demonstrates clear advantages:

• Superior mechanical properties versus alumina
• Enhanced wear resistance compared to silicon carbide
• Lower friction coefficients than silicon nitride
