43 simulation & software www.smart-molding.com Company profile Since 1998, SIGMA Engineering GmbH has been driving the devel- opment of the injection molding process with its simulation solution SIGMASOFT® Virtual Molding. This virtual injection molding machine enables the optimization and de- velopment of polymer components and molds as well as the mapping of the entire production process. The SIGMASOFT® Virtual Molding tech- nology combines the parts 3D geom- etries with its tooling and tempera- ture control system and integrates the parameters of the production process. This ensures a cost-efficient and resource-saving production as well as high-performance products – from the first shot. SIGMASOFT® Virtual Molding in- tegrates a multitude of process-spe- cific models including 3D simulation technologies that have been devel- oped and validated over decades and are being continuously optimized. The SIGMA Solution Service and De- velopment team support customers specific goals with application solu- tions. The software company SIG- MA offers application engineering, training, direct sales and support. A software straight from its develop- ers and designers to be a solution service to polymer engineering all over Europe. SIGMA Engineering GmbH, headed by Managing Director Thomas Klein, has subsidiaries in the USA, Brazil, Singapore, China, India, Korea and Turkey. In addition, SIGMA supports its users worldwide in a variety of in- ternational companies and research institutions with its Virtual Molding technology.
