Stamping refers to a set of operations performed on thin laminated sheet of various metals and non-ferrous alloys, so that a finished product is generally obtained at the end of the process in terms of shape and dimensions.
The operations are usually carried out with the aid of stamping tools, installed in presses. Stamping is manufacturing process in which the sheet is placed on a die and subjected to a force of a punch in order to acquire the geometric shape of the die.
Stamping is understood as the process of manufacturing parts by cutting or deforming sheets in cold pressing operation. Stamping operations can be summarized in three basic: cutting; bending and drawing. Stamping of the sheet can be simple, when performing a single operation, or combined in progressive processes. With the use of sheet metal stamping, we currently manufacture carbon steel, stainless steel and aluminium parts.
Due to its characteristics, this manufacturing process is ideally suited for the large series of parts, obtaining great advantages, such as: High production; Reduced cost per parts; Good finishing, requiring no further processing; Higher strength of parts due to conformation; Low cost of quality control due to uniformity of production and ease of detecting deviations.
At Newstamp we have progressive processes for high volumes, manual transfers for aesthetic parts and simple processes for reduced volumes. In the high volume parts (50.000 to 500.000 pieces / year) we try to automate to the maximum, in the aesthetic parts (8.000 to 40.000 pieces / year) we developed the processes to safeguard that the visible surface is aesthetically immaculate, thus cleaning the tools and the parts between operations is frequent. In the reduced cadence parts (2.000 to 10.000 parts / year) we try to obtain the pieces formed with the minimum investment in tools.
We also have extensive experience in deep draw parts (50 to 400mm deep) using part annealing.
Each reference has its production process properly characterized to ensure that all employees perform in the same way and they can consult it if there is any doubt.
The parts are controlled according to the requirement of the control sheet and often using control fixtures.
In the stamping we work in 2 shifts, to know more about our capacity and machinery park see the resources page.
