![]() ![]() Tube bending in PAM-STAMP was developed in cooperation with academic and industrial institutions. Its easy-to-use user environment ensures time-saving process setup and tool design and helps the user handle the complexity of hydroforming processes. Liquid bulge forming and high-pressure techniques can be modeled separately or combined within PAM-TUBE, covering the whole range of tube forming processes. Hydroforming is an advanced forming technique that gives the possibility of forming complex parts and improving surface quality. In response to market demand to form complex parts with small bend ratios, PAM-STAMP offers accurate tube bending simulation with realistic tool modeling and behavior for better forming results to avoid downstream problems. The complete value chain is nowadays available, allowing analyzing the complete press hardening process from initial part cost to distortion after quenching, cooling channel analysis, and a virtual reality check. This is again a step towards end-to-end virtual manufacturing – even if the challenge to simulate all the different aspects remains. The part performance in the final crash can also be tested virtually. The part manufacturing, with all its different aspects, can be virtually tested before the expensive hot forming process begins. This is a common area where Virtual Manufacturing can play an essential role in getting new processes running. With this new process, the stamp engineer is suddenly confronted with several new areas where he has to have high-level knowledge to get the process right.Įven for the most talented engineers, it's not feasible to become an expert in all these fields. The stamping department has to build knowledge in metallurgy, heat transfer, cooling, and fluid dynamics – typically, areas where several specialists are involved. Hot forming itself is a manufacturing technique where different fields will play together to make it work or not. ![]() This means that the crash engineers have to rely on the stamping department to manufacture the parts with the right properties. To get the properties of the end part right is crucial to achieving the crash performance. The whole chain has to be accounted for – from the early design stage. It even allows you to build small-sized vehicles with an outstanding crash performance – enabling the traditionally weaker group A cars to obtain 5 stars in the Euro NCAP crash tests (e.g., Fiat 500).īecause of this, looking only on the formability of the part during stamping doesn't make sense. Today all major OEMs work with hot-formed parts in their vehicles as crash reinforcements. This makes it a natural choice for the crash relevant parts in the car. ![]() No traditional available material that is formable is even close to the strength of the hot-formed steel. Hot forming is a rapidly growing and fascinating manufacturing technique, where the good formability of the warm blank is combined with exceptional strength of the end part due to the quenching in the tools. ![]()
