Cold forming

We transform sheet metal coils into finished metal components through cold sheet metal forming: we do everything within our factories, from design to delivery.

01.

Sheet metal cold forming: one process, endless applications.

Sheet metal cold forming is a plastic deformation process that changes the shape of the metal without using heat. Starting with raw material coils, we shape the material through specific moulds until we obtain the desired component.

It is a precise, repeatable and suitable for large production volumes and is the ideal technical solution for those seeking a constant result on metal components with two or three dimensional geometries, at competitive costs . At Sifral, we have been involved in this process for over half a century.

  • Three-dimensional hollow metal parts with notched edges, made by cold forming
  • Deep-drawn brass cups with side holes

Three dimensional hollow bodies

Cylindrical, conical or polygonal components obtained by progressive deep-drawing, made of different materials and thicknesses.

  • Cold-formed stainless steel clips used as precision structural parts
  • Dimensioned technical drawing of a precision structural part with a slot

Why choose the sheet metal cold forming.

Because it pays

The cold working of sheet metal does not require the use of heat, which results in lower energy consumption and a lower cost per workpiece. In addition, less material removal than other machining operations: less scrap, less waste, more efficiency. In large volumes, these benefits multiply and become a true competitive advantage.

Alternative to mechanical machining

For many components, sheet metal cold forming is a more efficient alternative to traditional machining such as turning or milling. If the geometry of the workpiece is compatible with this process, the benefits in terms of cost, cycle times and repeatability are significant. Companies often find out only after they try it, and there is no looking back.

03.

The real benefits for your production.

Choosing sheet metal cold forming means rethinking the production process in terms of efficiency: from the unit cost of the components to the quality continuity on even very large batches. An approach that, in the right hands, redefines and optimises the entire production.

Reduce production time and scrap

Optimisation of volume costs

Increased component repeatability

Quality continuity over time

Materials, batches and technical specifications.

We mainly work in stainless steel, but our experience in cold forming covers a wide range of metals. Choosing the right material is part of the co-design process we offer to each customer: based on the technical features of the component and its conditions of use, we are able to recommend the most suitable solution.
