Sheet Metal


Process Engineering
In engineering we have 5 mechanical engineers, equipped with 5 workstations DELL and 5 licenses of Visi-Progress software, where we develop our processes, tools, fixtures and special machines. 

All projects are developed by teams of 2 persons (project leader and toolmaker) to share knowledge and responsibilities. Projects are carefully reviewed to meet client requirements. 

Whenever we need to increase the capacity we outsource two external engineers that we have worked with in numerous different projects and they have the same software as us. We have an export/import to/from Catia and have possibility to supply numerical simulations with Autoform.
Stamping
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.

Surface Treatment
Newstamp has a network of partners specialized in surface treatment such as Anodizing, Cataphoresis, Lacquering, Zincing and Shot blasting. These are services we outsource weekly to companies in our region. We have been supplying components with surface treatment since 2004, but as we have a wide range of treatment types we have strategically decided to have partners to perform these services to us.
Assembly
At Newstamp we are constantly looking to add value to our components, so we naturally begin to perform assembly operations on some of our components so that the customer receives a complete set and not just a stamped part. The most common operations we perform are assembling bi-adhesive tapes, bonding textile elements as well as plastic parts. Being specialists in aesthetic parts it’s common the need to assemble the final product so that later on there’s as little handling as possible in the supply chain. We currently have 3 end product assembly stations and can quickly grow to embrace new challenges.
