Introduction

Metal can seamers are essential machines in the packaging industry, as they ensure the integrity and preservation of canned products. In this article, we will explore how these machines work, how to regulate them and the importance of proper maintenance.

Operation of the metal can seamers

1. Means of transport: The metal containers are moved along the seamer by means of cable or chain transport systems. A spindle doses the containers into the machine, and throughout the process, the stars convey the container and the lid.
2. Closure formation: During the closure cycle, the height of the container body is reduced to achieve the correct formation of the body hook and lid. This is done by exerting a constant and controlled pressure on the body of the container.

Regulation of metal container sealers

Each can seamer requires a specific regulation according to its specifications, format, tinplate gauges, type of lid and body. The quality of the closure depends on the design and mechanical condition of the metal can closer, as well as the selection of suitable tooling.

1. Plate pressure: Plate pressure during sealing is a crucial factor in the formation of a proper seal. The appropriate spring pressure depends on the size of the container to be sealed, and the necessary information can be obtained from the manufacturers of each can seamer.
2. Mandrel and rollers: It is essential that the mandrel is correctly dimensioned and that the profile of the rollers is adequate. Adjustment is much more delicate in form fillers, since their mechanical condition must be very good to avoid looseness in the mandrel arms, off-centering of the mandrel and compression plates, laminated closures and other closing defects.

Maintenance and training of mechanics

The training of the mechanics in charge of setting up the seaming machines is of great importance to ensure optimal operation and avoid problems in the seaming process. The metallographic or filling industries should provide adequate courses to their mechanics to ensure proper maintenance and regulation of metal can seamers.

Conclusion

Metal can seamers are essential in the packaging industry. To guarantee the quality of the closure and the preservation of canned products, it is crucial to understand its operation, to carry out a proper regulation and to maintain a correct maintenance. In addition, training of the mechanics in charge of these machines is essential to ensure optimum performance and avoid problems in the sealing process.
