How Cans Are Made

How many pieces are used to make a can? How involved is the process? Get an inside look at how the food and beverage cans we use every day are manufactured.

Ironing and DomingCup is forced through a series of rings to iron out cans to full length and form bottom dome.

Cans are spun as cutting tool trims to length.

Washer cycles hundred of cans per minute through multiple cleaning stations.

At printing station, cans are rolled against cylinder to print up to four colors simultaneously.

Inside SprayingA protective specially compounded coating is applied to inside of cans.

Can rims are flanged for future double seaming of ends. Then, each can is mechanically tested for leakage. Finally, cans are automatically stacked in cartons or on pallets for shipment.

The large coil of metal is cut into sheets at the rate of 160 sheets per minute on the shear press

The large coil of metal is cut into pre-scolled sheets at the rate of 150 sheets per minute. The irregular ends of the sheets are designed for the maximum number of ends per sheet.

An inside protective coating is placed on the sheets and cured.

An inside protective coating is placed on the pre-scroll sheet and cured.

The sheets are decorated with whatever printing the customer desires and then an over coat of varnish is placed on the decorated sheet and cured.

The body sheets are now stacked on pallets for shipment to a fabricating plant.

A second inside protective coating is placed on the sheets and cured.

Body sheets containing up to 35 body blanks per sheet are slit into individual body blanks which will be formed into cans.

The pre-scrolled sheets are now cut into small scroll sheets which will be fed into the end making press.

End FormingEnds are stamped out of the scroll sheets at the rate of 650 ends per minute. Finished ends are packed into tubes for delivery to fabricating plants and customers.

Body blanks are fed into a bodymaker where they are formed into cylinders and joined at their side seams by solder, cement or weld.

The formed cylinder comes from the bodymaker to the flanger. Here the metal on both ends is rolled to form a flange on each end of the can. This flange will at a later time accept double seaming.

One end, top or bottom, depending on customer specifications, is double seamed on the can.

A final coating is placed on the interior surface of the can. This is a specially compounded protective coating.

here the final interior coating is baked and cured through a funnel type oven where the time-temperature cycle must be controlled carefully.

A 100 per cent quality control inspection for any micro leak is given to every can.
