Aluminum die set

Product Overview
INNOVACERA zirconia ceramic necking dies are engineered for high-speed aluminum beverage can production, providing precise neck reduction with a mirror-polished working surface to minimize friction and material pickup.

Material and Construction
Manufactured from yttria-stabilized tetragonal zirconia polycrystal (Y-TZP), the die offers high mechanical strength and wear resistance. The precision-polished ceramic working surface supports smooth aluminum flow and reduces scratching and adhesion during multi-stage forming. Dies are configurable to match can diameter, neck profile, production equipment and forming stage requirements.

Key Benefits

• Extended tooling life to reduce replacements and downtime
• Consistent neck dimensions for reliable lid fit and sealing performance
• Reduced aluminum adhesion (pickup) to preserve can surface quality
• Mirror-smooth working surface that facilitates controlled material flow
• Stable performance at high line speeds
• Resistance to typical can-line coolants and corrosion

Typical Applications

• Aluminum beer cans
• Carbonated soft drink cans
• Energy drink cans
• Juice and ready-to-drink cans
• Lightweight, thin-wall aluminum cans
• Multi-stage can necking systems on high-speed production lines

How the Zirconia Ceramic Necking Die Works
The die progressively reduces the can opening to the required diameter and profile through successive forming stages. Its precision geometry guides the thin aluminum wall while the mirror-polished ceramic surface reduces friction and aluminum pickup, maintaining stable neck geometry and supporting reliable lid fit and sealing at production speeds.
