The basic element is the disk, which has
predefined characteristics in term of quality
(purity of the metal) and dimensions (diameter
and thickness). In the case of rectangular disks,
one begins with the outline, and after pressing,
shearing of the surplus flange is required.

The Production
Stages of a pot
Pressing or turning
The press forges the disk
, which roughly assumes the desired shape. Subsequently it is touched-up
to eliminate imperfections and is cleaned, giving the final appearance. For steel pots, a final working
step known as polishing is needed, which gives the sheen typical of this metal. Compared to pressing,
it allows an easy and quicker preparation of the machine, aiding therefore the passage from one size
to another in shorter times. It is carried out via the pressure of a lever on the cold sheet, which is
modelled by turning it on the underlying mould (a very similar concept to the manual working of
With the help of computers, the modern automatic lathes allow the generation of pieces which are
identical to one another, whereas the manual lathes still depend on experience and the hand of the
In the case of aluminum it passes along the stripping tunnel, guaranteed to clean
sufficiently to yield an object suitable for food contact.
Handles must meet certain important requirements to allow professional, safe and efficient
First of all, they must be made of a material which does not conduct heat, to prevent
the user from being burnt: for example tubular handles in inox steel are often used.
Plastics are largely used only in domestic products, seeing as though in the professional environment
high temperatures, long exposure times and the dimensions of the burner can compromise the handles.
One should not be fooled by the design, and instead, more functional aspects should be evaluated such
as the
safety of the handle
and the
stability of the joint
: therefore the welded joints or the number
of rivets with which the handles are applied to the body of the pot are also evaluated. Finally, the ease
with which it can be cleaned should also be taken into account.
The application of handles onto copper and aluminum pots is carried out by nailing them
onto the body of the pot with particularly resistant alloy rivets (AG5) or with rivets made
from the same metal as the container. For steel on the other hand, which is a very hard
material, the handles are soldered directly onto the body of the pot.
In both cases it is necessary to check that the number of points of attachment is proportional
to the dimensions of the recipient.To guarantee robustness and resistance, the dimensions
of the rivets should be assessed.
Handles are mostly made from steel
, in order to lower the
risk of being burnt. Only in the case of copper, is the use of brass handles preferred, and
this is due to aesthetic reasons.
For metal pots the main stages of production are as follows:
