The simulation for cold forming processes

Cold forming is a very widely used forming process for its numerous industrial advantages: high production rate, dimensional precision and excellent surface finish, material savings, little or no secondary operations required, improved mechanical characteristics.
Given the production of parts in large series in this area it is important that the fabrication sequence is perfectly calibrated in order to avoid negative impacts on the finished part. The deformation of the metal is able to generate defects on the part or the tool, the simulation makes it possible to be predictive and thus optimize the process.

Become predictive of your cold forming processes

Image_Fastener+Fixing

From the most traditional to the most demanding processes, the numerical simulation allows you to produce high added value forged components. Some of the most common cold forged parts include: shafts, hollow shafts, nails, screws, bolts, nuts, rivets, washers and fasteners.

With a simulation software, you become predictive of many things that influence your costs and the quality of your parts :

  • Anticipate the presence of defects: position, evolution, depth of folds...
  • Prevent deformation, wear and tear and tool breakage at any stage of the process
  • Select the adequate forging equipment according to the effort of forging, consumed energies... 
  • Assure the health of your parts with good fibering
  • Visualize critical zones subject to damage
  • Follow cutting surfaces, segregated areas and suction defects 

These criteria can be simulated with our simulation software COLDFORM® for the numerous processes including closed die forming, extrusion, cutting, punching, rolling, heat treatment, machining, and many others. It is suitable for any type of metallic alloy.

Design a suitable and resistant tool

To resist constraints and high rates of current production, the tools used in cold forming require high-performance properties: excellent resistance to fatigue and high wear resistance.The software FORGE® and COLDFORM® allow to predict all these constraints and thus optimize the design, costs and tool maintenance.  


Tool life can be extended with the analysis capacity of the simulation softwares.. Thermal or thermo-mechanical calculations in tools can be conducted to predict the stress distribution, deformations, wear, temperature and damage to any moment during the process.

FORGE® and COLDFORM® allow two types of analyzes: a fast decoupled calculation in matrices as well as a coupled calculation unique between workpiece and tools. The softwards offer a very large press database: mechanical press, hydraulic press, toggle press and orbital press. complex piloting can also be set. Tools preloaded and mounted on springs can easily be defined.

Important benefits for your activity

The simulation accompanies you and helps you in key moments: 

  • During the R&D phase, for the development of innovative or complex products
  • During the quote phase, to be able to quickly position itself towards a new manufacturer
  • During the design and development process, to speed up the time to market
  • During the production phase, to control the manufacturing costs
