How Are Beverage Ends Made?
This video explains the manufacturing process of beverage can ends, detailing each step from coil feeding to final packaging. Beverage ends, also known as lids, go through multiple forming, sealing, and conversion steps before they are ready for shipment.
Step-by-Step Manufacturing Process
1) Shell Press: Forming the Shells
Aluminum coil is fed into the Shell Press, where individual shells (unfinished ends) are stamped out.
2) Curler: Creating the Curl
The Curler forms a precise curl on the shell’s outer edge, which is critical for seaming the end onto a filled can.
3) Balancer: Managing Line Flow
A Balancer temporarily stores and releases shells based on line demand, ensuring a continuous production flow.
4) Liner: Applying the Sealing Compound
The Liner injects a sealing compound into the shell’s curl. This compound ensures a leak-proof seal when the end is later attached to the can.
5) Compound Dryer: Curing the Liner
The Compound Dryer cures the applied sealing compound, allowing it to properly bond to the aluminum surface.
6) Second Balancer: Managing Lined Shell Accumulation
Another Balancer provides storage and accumulation for lined shells, maintaining a steady supply to the next stage.
7) Conversion Press: Forming the Easy Open End
Shells and tab stock feed into the Conversion Press, where the stay-on tab is attached, and the shell is transformed into a fully functional Easy Open End.
8) Packaging Center: Preparing for Shipment
Finished ends are stacked, counted, and packaged, ensuring they are protected and ready for shipment to can filling plants.
