Integrative Simulation

Integrative Simulation
  • Integratively simulate parts using reinforced plastics or reactive PU-foams

Material processing has a big impact on part performance. Before a structural load case can be studied, a process simulation needs to be performed. Ultrasim® is the pioneer in integrative simulation for plastic and foam applications, focusing on the impact of material processing on part performance. Since 1999, we have been providing comprehensive simulations for SFRPs (short fiber reinforced plastics), reactive PU foams, and particle foams, optimizing design and production processes for high-quality plastic components.

Static and Dynamic Mechanical Simulation

Improve product quality and reduce development times with Ultrasim®'s mechanical simulation. Analyze and optimize component performance for improved structural integrity.
  • Analyze and optimize structural integrity and performance of components and parts

Ultrasim® enables comprehensive static and dynamic mechanical simulation, allowing you to analyze and optimize the structural integrity and performance of components and parts for improved product quality, reduced development times, and ultimately cost savings. Two major characteristics of Ultrasim® are fundamental for its high accuracy: First, its unique material model considers most of the specific properties of thermoplastic materials, such as anisotropy, strain rate sensitivity, tension-compression asymmetry, and temperature dependency. Second, it uses an integrative approach by using fiber orientation information from the process simulation to determine material anisotropy in each integration point of the mechanical simulation model.

How to analyze and optimize the performance of components and parts

Injection Molding Simulation 

Revolutionize your injection molding process with Ultrasim®'s advanced simulation tools. Optimize tool design, mold troubleshooting, and the molding process for efficient and effective production.
  • Part and mold design
  • Optimize molding process
  • Process and mold troubleshooting

Injection molding simulation utilizes advanced tools and techniques to assist with tool design, optimize the molding process, and troubleshoot mold-related issues. It helps ensure efficient and effective production by analyzing factors such as filling behavior, pressure behavior, and early identification of potential issues during the development phase.

How to support tool design, optimization, and troubleshooting

Polyurethane Simulation

Unlock the full potential of polyurethane simulation for tool design, optimization, and predicting part properties. Discover how Ultrasim®'s advanced PU simulation tools can help you identify issues early on and optimize the foaming process.
  • First-time-right part and process design
  • Accelerated mold prototyping
  • Trouble-shooting of foaming processes
  • Predicting part performance 
We support you to optimize your PU foaming process and mold regarding robustness and performance. Our in-house simulator predicts the flow and expansion of our PU foams in your mold. Issues like the formation of voids or thermal hot spots can be avoided by design before the first prototype is manufactured. We predict the density distribution in the mold and its impact on the mechanical and insulation performance of your part.
