Down Gauging and How It Affects Our Windows of Runnability

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. 

 

 

Aluminum Conversion Costs Parameters

Filler demands:

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

Starter gauge

Tool design

  • Cupper
  • Bodymaker
  • Necker
Canmaker technologies

Can design

  • 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.
