Oiling (DOS), a crucial step in canmaking

In the metal packaging industry, oiling is an essential process carried out on the surface of cans to ensure proper sliding during manufacture and transport. This procedure not only facilitates can handling, but also plays an important role in preventing abrasions and other damage that can compromise the integrity of the can.

Oil DOS: Dioctyl Sebacate

The oil used in this process is known as DOS, an acronym for Dioctyl Sebacate. This oil is selected for its non-reactive properties and its compatibility with food packaging processes, complying with FDA and USDA regulations. In addition, DOS provides a protective film that prevents direct contact of the metal with other objects, thus reducing the risk of abrasions and scratches.

DOS Oil Application

The application of DOS oil is carried out at a later stage after tinning and passivation of the cans. By means of rollers or spraying systems, a thin and uniform layer of the oil is distributed over the entire surface of the can. This process is carried out with precision to ensure that the right amount of oil is applied, avoiding excesses that could cause problems in later stages of manufacturing or in the packaging of the product.

Benefits of Oiling in Can Manufacturing

• Lubrication: Oiling improves the sliding of cans through production lines, facilitating operations such as stamping, forming and seaming.
• Corrosion protection: By forming a barrier against moisture and oxygen, DOS oil helps prevent the formation of rust on cans during storage and transport.
• Improved package quality: By avoiding abrasions, oiling contributes to maintaining the aesthetic appearance of the package, which is essential for the presentation of the final product.

Considerations in the Oiling Process

It is essential to use acid-free oils so as not to compromise the quality of the container and the product contained. In addition, during transportation and handling of the cans, it is important to avoid jamming and excessive friction that can wear away the oil layer and expose the underlying metal.

Conclusion

DOS oiling is an important technical step in the production of metal cans. Its correct application is crucial to ensure the quality and durability of the packaging, as well as to optimize the manufacturing processes. With the use of this oil, the metal packaging industry guarantees that the products reach the final consumer in the best possible conditions, maintaining the food safety and aesthetic quality standards demanded by the market.
