Technically, the roots of SIGMASOFT® go back to a MAGMA R&D project in the mid-1990s, which was focused on a new coupled heat flow / fluid flow solver for non-Newtonian flow of semi-solid aluminum. Today, after 20 years of ongoing development, the SIGMASOFT® Thixo module allows the prediction of all relevant phenomena occurring at mold filling and solidification of semi-solid processed Aluminum and Magnesium. The covered processes are Rheocasting, Thixocasting, Thixomolding®, Metal Injection Molding etc…

Typically, all semi-solid metal casting processes have critical small process windows. So mold concept and layout of the casting process have to be developed much more accurately than in “normal” metal casting – and preferably hand in hand with the part design.

SIGMASOFT® Thixo is an easy-to-use tool to answer those questions by reproducing exactly the same working conditions as in the casting machine and runs several cycles one after other. Electrical heating devices can be simulated exactly as in reality, with all the information about their material, power and control system. In this way, the thermal layout of the mold can be understood and optimized.

SIGMASOFT® Thixo uses an intuitive graphical user interface to guide the user through the setup step by step. An intelligent meshing algorithm generates a 3D mesh for a complete mold within less than 5 minutes. The possibility to load in complete mold geometries allows SIGMASOFT® Thixo to truly look into the process.
