CanSCHOOL Spotlight: Compressed Air in the Bodymaker

As the punch and ram retract after forming the can, compressed air plays a key role in the process.

Air is released through the center die of the domer to help eject the can—and simultaneously, compressed air flows through the center of the ram into the can itself.

This not only assists in stripping the can off the punch, but also prevents vacuum pressure from collapsing the can as it’s removed. From there, the can drops into the takeaway system and heads to the trimmer.

$CanSCHOOL Spotlight: Bodymaker Alignment In a bodymaker, alignment is everything. The punch, redraw die, and ironing dies must remain concentric to control how aluminum flows through the draw and iron process. Even slight misalignment introduces uneven forces; leading to defects like pleats, fractured domes, cracked flanges, along with excessive tooling wear. The cradle is what holds the system together, providing the structural foundation that maintains alignment across the die pack and forming components. With the ram position fixed, overall alignment depends on how precisely the cradle and its supporting components are set relative to that axis. This includes the redraw sleeve, cup locator, stripper assembly, and domer. #CanSCHOOLSpotlight #CanMaking #Manufacturing #Engineering #MetalPackaging #AluminumCans #ForCanMakersByCanMakers$
