Eliminating 3 Common Necker Match Gap Issues in Can Production

Match gap on the necker is defined as the radial clearance between necking die inner diameter and the knock-out outer diameter. Knowledge of the match gap and how it is impacted by production can resolve common necker spoilage issues.

 

When experiencing collapsed or puckered cans in the necking process, the match gap design is not the only factor to review. Production parameters like trimmed can topwall, coating thickness, air gap, and temperature changes impact metal thickness and material efficiency in the necking stage. Understanding the full design of the can making process ensures the correct selection of necking dies and knock outs both in size and material to avoid common challenges.
