How cans are made
Cans for food, drinks and non-food products may be constructed out of either two or three pieces of metal.
The first cans ever produced were three-piece and they were developed in the middle of the 19th century. They consist of a cylindrical body rolled from a piece of flat metal with a longitudinal seam, usually formed by welding, with a top and bottom, each seamed on the ends of the body.
Three-piece cans may be manufactured in almost any practical combination of height, diameter and shape. This process is particularly suitable for making cans of different sizes as it is relatively simple to change the parameters of the can under production.
The Cazander Brothers mainly have machinery for three-piece cans in stock.
What is an assembling machine?
An assembling machine inserts an aluminium (covering) foil into a can, to protect its contents.
The machine is often part of the end making; at the end of the production process the aluminium foil is fitted into a ring which is placed on the top inside of a tin can after which the lid is fixed.
This foil is used purely for hygienic reasons, for example with baby powder. The sequence from bottom to top is: ring (to attach the foil), aluminium foil, lid, plastic cover.
Cazander Brothers regularly offers quality used Oberburg and TDV assembling machines from their extensive stock.
