COLDFORM® is a finite element analysis software dedicated to the simulation of cold forming processes. Its advanced functionalities cover a very wide range of applications including cold heading for fasteners, cold rolling and sheet metal forming. Thus, the parts simulated are found in multiple sectors: fastening solutions, aerospace, automotive, medical, fine watchmaking.
The benefits of COLDFORM® can be observed at all steps in your activity:
During the R&D phase, for the development of innovative or complexe products :
reducing design costs
reducing development costs
During the production phase, to optimize the various forging steps and improve manufacturing processes :
reducing costs related to prototyping and workshop testing
reducing the quantities of materials used
optimizing the manufacturing processes
extending die service life
During the negotiation phase, thanks to the control of production costs and improved schedule reliability:
considerably shortening the design phase
reducing material costs
reducing time-to-market
controling risk provisions
COLDFORM® allows you to precisely predict:
the exact geometry and dimensions of the final parts, taking spring-back into consideration
material yield through forming sequence
possible underfillings and folds
fibering and stress distribution
marking and monitoring of specific surfaces, such as cutting surfaces, from the initial billet to the final shape
damage and rupture criteria
residual stress distribution
… but also material displacement, plastic deformation, temperature and all other user-defined variables.

The tools of cold forming undergo strong mechanical and tribological stresses during their life cycle. These can lead in certains cases of damaged premature tools. The tools represent an important part of the manufacturing cost of a part; thus it is essential to anticipate well these problems during the designs.
COLDFORM® allows you to analyze mechanical die strength in order to extend their service life. The software can compute stress distribution within the die, along with deformations, wear, temperatures and damage at any time during the process. COLDFORM® can carry out rapid analyzes which consist in applying stresses obtained during the forming process computation, to the tools. Moreover, COLDFORM® is capable of performing coupled part/tool computations, giving extremely precise results.
Thanks to the functionalities dedicated to pre-stressed dies, it is possible to accurately determine the value of the necessary pre-stressing of the interference fit of the tools. By playing on the shape, the number of rings and materials that it composes, COLDFORM® allows you to find the best design for your tools and to guarantee the best performance and durability.
