In this video, we will discuss the various processes involved in turning a coil of aluminum into a finished can. From metal preparation to forming, coating, and curing, everything must work in unison to deliver quality cans to our customers.

The can-making process begins at the cupper, which takes aluminum coil and produces a blank. This blank is then drawn into a cup, marking the first transformation in the process.

The next step occurs inside the Bodymaker, which is responsible for four key progressions: the redraw die and three ironing dies. The redraw die changes the cup into a can, while the three ironing dies further refine the can's dimensions by thinning its walls until it reaches its final height.


At the end of the Bodymaker's stroke, the can has a dome shape, a final diameter, and a jagged edge along the top.

After the Bodymaker, the can moves to the trimmer, which removes the jagged edge. This process is critical, as a trimmed can emerges clean and free of debris, though it may still have residual lubrication and oil.

Next, the can is sent to the washer to remove all lubrication and coolant. Once cleaned, it proceeds to the dry off oven, resulting in a "bright can." This term refers to its shiny appearance after all contaminants have been washed and dried, preparing it for decoration and internal coating.

The decorator applies the external label to the can. After decoration, the can enters the pin oven, where the wet decoration is cured to ensure durability.

Following decoration, the can moves to the IC spray machine, which sprays a protective lacquer on the inside. This lacquer prevents the beverage from coming into direct contact with the aluminum, ensuring both the beverage's safety and the can's integrity.


The lacquer is then cured in the internal bake oven (IBO), completing the internal coating process.

The next stage occurs in the necker, aptly named for its function. Here, the can undergoes a necking process, where each stage narrows the neck further until it reaches the final shape. After necking, the can receives a flange, which will later secure the lid or end once the can is filled with a beverage.
