ADSTEFAN-Casting Simulation System

Time, High Accuracy. ADSTEFAN can solve all losses by all defect.
“ADSTEFAN” is a CAE system which can contribute to the decrease of trial & error, reduction of lead time, and cost reduction by analyzing the process of molten metal flow and solidification, and visualizing the process, and preventing casting defects from generating at initial stage.
 
Trusted CAE System
ADSTEFAN is a casting CAE system, which is researched and developed by experts gathered from many casting industries and universities including Tohoku University in “casting CAE workshop” for about seven years, and is made into a project by Tohoku Techno Arch. So, that is why the system has a high reliability by utilizing and supporting by many users.

Solver

  • Fluid Flow Analysis : Melt flow is simulated. Filling sequence, pressure, and temp change can be observed.
  • Solidification Analysis : Macro porosity, size and geometry of shrinkage porosity are predicted.
  • Die Temperature Analysis : The series of die temperature by setting of each process(Shot, Mold Open, Ejection, Blow) can be analyzed. By the setting of parting agent spray and water volume in cooling tube, the accuracy of analysis is improved, and the effect by spot cooling can be also evaluated.
  • Sleeve Analysis : Behavior of molten metal in sleeve due to the plunger movement is simulated, and the analysis visualizes how the metal is injected from sleeve.
  • Gas-Liquid Flow Analysis : Coupling flow of air and metal are calculated so that it is used for optimization of low pressure die-casting or vacuumed casting.
  • Temperature Data Map : Mapping to the result by ADSTEFAN to the FEM’s mesh.
  • Leak Prediction : Prediction of leak's route from location of porosity and cooling tube.
  • Linkage with JMatPro : Importing material properties to ADSTEFAN’s database.
