Beverage can making process: Training videos (Part 3)

Videos which show the drying and initial internal coating parts of the beverage can making process are now available to watch online. There is an explanation of each part of the process above each video. This latest upload continues CanTech’s look at how a beverage can is produced. Keep checking back for new videos. Videos are courtesy of Ball Packaging Europe. The idea of these videos is to help those who are new to the industry to learn about can making.

Part 7: Drying

The drying oven is basically divided into three zones (two heating zones and one cooling zone). The heating zones serve to heat the cans and to evaporate the fluid constituents as well as to cross link the coating and the printing ink. The air in the heating zones is recirculated to reduce the amount of fresh air which has to be heated.

The exhaust air is supplied to the thermal incineration unit where the exhaust gases from the oven are incinerated to carbon dioxide and water without any residue. After leaving the heating zone, the cans are conveyed to the cooling zone and are adapted to the ambient temperature.

Part 8: Initial internal coating

Inside the internal coating machine, the can is conveyed to a coating turret and positioned on a vacuum plate. It is set into rotation and passes two spray guns, the first one which coats the lower section of the body and the second the body and the base.

When the spray guns have applied the required amount of coating, the can is conveyed via a discharge belt to a collective conveyer and to the internal coating drying oven connected downstream.
