The Step-by-Step Can Seaming Process
1. Container Infeed & Precision Positioning
Whether integrating with an automated line or running a manual batch operation, specialized alignment guides securely position tin, aluminum, or plastic containers to prevent spillage and guarantee consistent centering.
2. Synchronized Lid Placement & Pre-Press
The automatic cap feeder releases and matches each lid with precision. A heavy-duty pre-press assembly clamps the lid firmly onto the container body, preparing the assembly for flawless seam formation.
3. Dual-Operation Double Seaming & Inspection
First and second-operation seaming rollers engage sequentially to fold and compress the metal layers into a certified hermetic seal. Continuous monitoring options verify tight tolerances to eliminate leakage risks.
4. Automated Outfeed & Easy Clean-Down
Finished cans transition smoothly onto the discharge conveyor for downstream labeling or packaging. The sanitary open-frame design allows operators to quickly sanitize components and swap tooling for different can sizes.
