Cold forming

As one of the worlds leading cold forming companies, we offer quality cost efficient cold formed fasteners, complex components and assembly parts to precise specification. For over 120 years we have been setting the pace as Europe’s leading manufacturer of cold formed fasteners and parts with sites in the UK and throughout the world. 

Nedschroef offer a complete manufacturing solution for cold formed parts and fasteners, from design, though to supply chain management, stock and delivery. Our cold formed parts can be efficiently fed straight into production lines in the UK and Europe, on demand. 

The cold forming process includes

Coiled metal wire, which is fed into a machine and precisely sheared to length. The cut pieces called blanks are then moved through several sequential extrusion and upsetting stations. There, they are pushed into progressive carbide dies at room temperature using nothing but sheer power and high speed. This forces the metal to be formed into its desired final shape which is retained upon die removal.

A multi-station cold forming machine processes blanks at all stations simultaneously, each in a different stage of development. With every stroke of the machine, a finished cold formed part is ejected from the last die. In parallel, a new blank is being sheared to an engineered length and fed into the first die. This enables production rates to hit hundreds of cold formed fasteners and parts per minute, leaving machining processes far behind when it comes to speed.

Some components may not lend themselves to the cold forming process due to incompatible shapes. Yet, our state-of-the-art cold forming machinery allows us to produce ever more complex components with incredible accuracy. Even when secondary machining operations are additionally applied, cold forming as the base manufacturing process still proves to be the most cost-effective solution.

Benefits of Cold Forming

  • Economies of scale because of high production rates
  • Increased strength due to grain structure rearrangement
  • Design versatility by using multiple progressive dies
  • Little to no waste thanks to mitigation of material removal

Nedschroef are the only global fastener company to have developed its own cold forming machines. Whilst we have deep roots in the automotive sector, we can also supply cost effective cold formed parts to: aerospace, hydraulics, defence, pneumatics, pump, fan, electronics, engineering and OEMs.
