Press Release Summary:

Simulation Software integrates all elements in mold.

Jul 27, 2012 - With reengineered solver technology and meshing concept, SIGMASOFT® v5.0 can cut simulation time required in elastomer applications. Meshing technique uses unstructured meshes, which can automatically mesh finer regions where complex thermal and flow phenomena take place, such as part boundaries and thin walls. It can also save mesh elements in regions where fewer interactions take place. Through parallelization, solver architecture makes it possible to exploit potential of multi-core technology.

Press release date: Jul 26, 2012

Thanks to a completely reengineered solver technology and a revolutionary meshing concept, with SIGMASOFT® Version 5.0, the simulation time required in elastomer applications can be reduced by up to 80%. With this dramatic speed-up, simulation can now be integrated in the elastomer processing on a daily-basis, both for part design and process troubleshooting.

Schaumburg, IL, - At the DKT conference in Nuremberg, Sigma Engineering GmbH, Aachen, presented SIGMASOFT® Version 5.0, the latest release of its process-oriented simulation software. With a completely reengineered solver technology and a new meshing concept, calculation times have been dramatically reduced, while keeping all the advantages of accuracy and user friendliness of a complete 3D-simulation approach.

"With SIGMASOFT® Version 5.0, we have achieved a major breakthrough in injection molding simulation," explains Dr. Marco Thornagel, Executive Manager at Sigma. "Some years ago, users had to wait sometimes days to get the results of a simulation. It was not viable to use simulation to support every-day production activities, or to quickly optimize products. Now, however, simulation can be part of the daily production tools used in the mold shop or in the production floor, to deliver reliable and profitable answers both to design new products and to optimize existing molds."

SIGMASOFT® is still the only option available in the market to seamlessly integrate all elements in the mold within the simulation. Thanks to the implementation of "Finite Volume" numerical methods, not only can the cavity be considered in the simulation, but also the complete real mold configuration, including tempering channels, heating elements and inserts. SIGMASOFT® is and has always been based exclusively in 3D technology, developed over a quarter century. The mesh required to conduct the simulation is generated effortlessly by the user in only minutes, without requiring any manual optimization.

The new meshing technique in the latest version of the software uses "unstructured meshes." These are basically "intelligent meshes," which can automatically mesh finer regions where complex thermal and flow phenomena take place, such as part boundaries, thin walls or complex runner systems. It also can save mesh elements in regions where fewer interactions take place, such as mold boundaries. The calculation effort is reduced and the productivity of the software increases.

Through parallelization, the new solver architecture makes it possible to exploit the complete potential of multi-core technology in state-of-the-technology computers. Beyond a significant reduction in computational time, the technology now allows users to simulate more complicated injection molding processes. This will be now the focus of further developments in the software, according to Sigma sources.

SIGMA® ( is 100% owned by MAGMA® (, the world market leader in casting process simulation technology based in Aachen, Germany. Our SIGMASOFT® process simulation solution optimizes the manufacturing process for injection molded plastic components. SIGMASOFT® combines the 3D geometry of the parts and runners with the complete mold assembly and temperature control system and incorporates the actual production process to develop a turnkey injection mold with an optimized process.

At SIGMA® and MAGMA®, our goal is to help our customers achieve required part quality during the first trial. The two product lines - injection molded polymers and metal castings - share the same 3D simulation technologies focused on the simultaneous optimization of design and process. SIGMASOFT® thus includes a variety of process-specific models and 3D simulation methods developed, validated and constantly improved for over 25 years. A process-driven simulation tool, SIGMASOFT®, with its comprehensive simulation approach, provides a tremendous benefit to production facilities. Imagine your business when every mold you build produces required quality the first time, every time. That is our goal. This technology cannot be compared to any other conventional "Design" simulation approach employed in plastics injection molding.

New product success requires a different communication between designs, materials, and processes that design simulation is not meant for. SIGMASOFT® provides this communication. SIGMA® support engineers, with 450 years of combined technical education and practical experience, can support your engineering goals with applications specific solutions. SIGMA® offers direct sales, engineering, training, implementation, and support, by plastics engineers worldwide.
