Sand Casting
A comprehensive sand casting simulation software for both ferrous and non-ferrous castings.

Powerful

EKKcapcast calculates a wide range of data using advanced techniques and powerful solvers. A complete data set assures you have everything you need to get your casting right the first time.

• Fill Time Prediction
• Cold Shuts
• Riser Sizing & Placement

• Pipe Prediction
• Porosity Prediction

Accuracy

The high quality FEM meshes produced by EKKcapcast, coupled with powerful two-phase flow simulation solvers, result in unprecedented levels of accuracy. Properties such as the changing viscosity of an alloy as it cools can be modeled, thereby directly and visually predicting mis-runs. Simulation results are consistently verified by real world castings.

Heat Transfer

EKKcapcast’s thermal analysis module uses zero-thickness interface elements to connect components and accurately model heat transfer between them. Temperature dependent material properties, thermal expansion, and changing water content in green sand are all modeled. The ability to analyze casting temperatures, solidification patterns, and thermal effects throughout the entire process is an indispensable tool.

Solidification & Porosity

Thermal results are used to predict hot-spot locations and sites of potential defects. Optimal chill placement can be quickly determined using hot-spot data to improve feed paths. The porosity module uses material property data to greatly improve the quality of predictions. Porosity defects, temperature gradients, and cooling rates are taken into account by the software to accurately determine mechanical properties. The effect of inoculation can also be observed in the porosity results.
