Manufacturing Simulation Reduces Development Costs and Time in Cold Forming Tool Design

Omni-Lite Industries is an advanced material company. They recently designed a new part that was exhibiting a unique material flow. The part was cold formed out of 1100 aluminum material.

The initial tool design was completed and reviewed using the Simufact.forming simulation. Upon initial review, everything seemed to be acceptable, with the exception of the volume of material in the flange of the part. The second station trap extrusion die radius was then reduced in order to accommodate the material volume requirements.

Accurately Predicting the Behavior of Pneumatic Tires

When developing the sub-systems of a vehicle, compromises have to be made among several contrasting objectives. On one hand, one wants to set all sub-systems – such as suspensions – so that they allow efficient and safe handling of the vehicle. On the other hand, comfort cannot be sacrificed too much. Being the support of the vehicle and providing forces necessary to control it, pneumatic tires are one of the most important components. However, it is very challenging to model them due to both their complicated composition and the materials used in their manufacturing process. On top of that, the modeling is done by suppliers and an in depth understanding of the interaction with the vehicle must be attained.
