Basics of coldforming

Cold forming allows you to produce parts with superior mechanical properties at high speeds, with a minimum to no waste. This technology provides an attractive alternative to conventional production methods. 

Cold forming technology 

Step into the world of Nedschroef Machinery and the fascinating field of cold forming. Discover the fundamental principles that make it an essential manufacturing method. ‘Cold forming’, or ‘cold forging’ allows precision components to be made with unparalleled efficiency, precision, and excellence.

Nedschroef Machinery is at the forefront of cold forming technology, offering state-of-the-art solutions that leverage core principles and advantages to enhance your manufacturing operations. With our expertise and commitment to innovation, we are ready to shape the future of your industry.

Cold forming has always been our core business and key competency. With this manufacturing process, we produce metal parts at the highest speeds and precision and contour parts before further processing.

The cold forming process

  • Coiled metal wire is fed into a machine and precisely sheared to length.  
  • The cut pieces (‘blanks’) are moved through sequential extrusion and upsetting stations. There, they are pushed into progressive carbide dies at room temperature using sheer power and high speed. 
  • This forces the metal 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 sheared to an engineered length and fed into the first die.

Production of hundreds of cold formed parts per minute

We're leaving machining processes far behind when it comes to speed. Some component shapes may not lend themselves to the cold forming processes. However, our state-of-the-art cold forming machinery allows us to produce even more complex components with great accuracy. Even when secondary machining operations are applied, cold forming as the base manufacturing process often proves to be the most cost-effective solution.

Benefits of Cold Forming

  • High production rates in comparison to conventional machining
  • Increased strength due to grain structure rearrangement 
  • Design versatility by using multiple progressive dies 
  • Reduction of raw material consumption
