Lade Drinks – Getränkedosen bedrucken

Aluminum cans are hugely popular as containers for beverages ranging from soda to beer. These thin, glossy, lightweight cans line supermarket shelves holding the drinks we all know and love. But just how does a soda can start? How do they make aluminum into cans? Let me tell how cleverly sheets of this aluminum are made into convenient beverage cans.

First, five and a half inch diameter circles are cut out of a thin sheet of aluminum. These circles are called blanks. The blanks are drawn up at the edges to form short sides. This can now looks a bit like small tuna can.

Next, all the little “tuna cans” are stacked on their sides in a chute that carries them to a special machine. This machine is called the “draw and iron machine”. As they enter the machine, the cups are held tightly by snug sleeves of metal. In the blink of an eye, each horizontal can is slammed into from one side by a cylindrical mold called a punch. The resultant elongation of the can around the mold forms what looks like the bottom of a can with a jagged top edge.

Next, this unavoidable wavy edge is trimmed off and the cans proceed to the washing area. The washing process consists of six cycles. The first two washes are with warm hydrocloric acid, to add shine. The next four are with warm neutralized water which removes all traces of acid. The clean cans emerge from washing shiny and attractive and are air dried before printing.

Printing the beverage cans is a quick and clever process. The cans are held against spinning inked rollers, and each color is applied one at a time in layers. After inking, the cans are baked to ensure that the ink in dry and smudge-proof. A few minor but necessary procedures are performed on the cans before they move to the last shaping stage. For instance, the inside of the cans are sprayed with a water based coating that is supposed to keep the aluminum taste from getting into the drink.

Lastly, the cans go into a final shaping machine called the “necker”. As you may have guessed, the necker forms the necks and tops of each can. This is done by gently “choking” the top of the cylindrical can into a smaller “neck” and adding a lip to the top. This lip is folded over a receiving lip on the actual pull tab lid, and is the part you put your lip against when drinking from a can.

So there you have it. The can is finished as far as the actual manufacturer is concerned. Later, when the drink manufacturer is ready to put the lid on after filing the can, the lid is simply placed on top and the can lip folded over it. The beverage is now conveniently contained in the aluminum can and is shipped of to the stores where ordinary folks will buy and drink from the can, many oblivious to the journey this can has taken from metal sheet to handy container.
