• To develop a strategic innovation plan for the double seaming technology.
• Applying our experience and know-how.
• Contributing to metal can innovation.
• Deeping into the process, to achieve the technological market dominion.
• Thus becoming leaders and world reference in shaped cans double seaming.

 

When a new can design is introduced, the can may be seamed but …

• The seamer becomes less reliable, some systems are underspecified for the new cans.
• The seaming tools and other seamer components durability decreases.
• The seamer needs continuous stops and adjustements.

Many times the seaming is the real obstacle:

• Often underestimated at the first stages.
• Problems arise from today’s innovation needs.
• May block innovative can designs.
• Non-round DR tinplate cans.
• Complex shape cans.

 

Original design (2.95 mm seam height, 0.16 mm lid, 15 mm corner radius)	Proposed redesign (2.40 mm seam height, 0.17 mm lid, 18 mm corner radius)
(Plan view of chuck and lid flange strip after one 1st operation. Simulation results)
Sharp, locally concentrated wrinkles, very difficult to iron in second operation. Overall conclusion: non acceptable seam (verified by tests)	Lid flange strip shows very smooth uniformly distributed wrinkles, which will be easily ironed in the second operation. Probably only one first operation will be needed. Overall conclusions: proposed redesign will definitely yield an acceptable seam.

 

Why use Seaming Simulation in metal can design?

• Accelerates market lead-time.
• Saves development costs.
• Allows innovation while minimising risks.
