Down Gauging and How It Affects Our Windows of Runnability


Presented by David Lieb

Light weighting as a technology driver


The canmaking industry is globally challenged to light weight and improve efficiencies. But our industry has different regional requirements. Sometimes we need different solutions to accomplish the same challenge.

Filler demands:

  • Drop / DRP requirements
  • Axial load
  • Stackability?
  • Filler technology
  • Country infrastructure
  • End size

Starter gauge

Tool design

  • Cupper
  • Bodymaker
  • Necker

  • Thinwall
  • Thickwall
  • Dome Profile


Achieving the largest windows of runability helps us to meet this challenge.




Light weighting with largest "windows of runability"


If we do it WRONG:

We create narrow windows of runability

  • Leave unnecessary metal in the can
  • Increase the risk of B/m tearoffs
  • Increase risk of higher neck spoilage
  • Increase risk of dome squat causing flange width and neck spoilage issues
  • DRP, drop and axial load issues
  • Wrinkled dome issues

We reduce line performance.

If we do it RIGHT:

We create large windows of runability

  • Lighter weight optimized can
  • Lower tearoff rates than prior to light weighting
  • Maintain good can specs for DRP, drop and axil load
  • Maintain dome squat values equal to or better than before light weighting

We can actually improve line performance.
