Cast-Designer Investment Casting Advanced Flow, Solidification & Stress Simulation

For Lost Wax Investment Casting

Introduction

Investment casting is a highly precise manufacturing process capable of producing complex components with excellent surface finish and dimensional accuracy. However, due to the high pouring temperatures, complex gating trees, thin sections, and ceramic shell interactions, achieving defect-free castings requires accurate control of metal flow, heat transfer, solidification, and thermal stresses.

Cast-Designer Investment Casting is an advanced simulation solution that combines intelligent design automation, expert knowledge-based engineering (KBE), and high-accuracy CAE analysis to optimize the complete investment casting process.

  • Gating tree design and mould filling
  • Shell radiation effects and enclosure behaviour
  • Solidification and porosity prediction
  • Thermal stress and distortion analysis
