Detailed analysis of mold designs is becoming increasingly necessary as advanced mold technologies are adopted. Conformal mold cooling is a cooling technique that aims to offer optimal cooling conditions exactly where you need them. The technology has been around for many years, but has become a real option now with the better and cheaper ways to manufacture conformal cooling cores. Hot runner systems are very commonly used in plastic injection molding. Although these are simple systems on the surface, what actually happens inside the hot runners and how they lose heat into the mold can be quite complex. With the Cool (FEM) functionality inside Autodesk Simulation Moldflow software coupled with Autodesk® Simulation CFD software, you now have the capability to model even the most complicated conformal geometries and hot runners in full three-dimensional detail of all components. This process enables you to evaluate and optimize the hot runner and conformal cooling design to achieve an optimal mold design and injection molding process.

Key Learnings

  • Use Simulation Moldflow Insight to evaluate whether an investment in conformal cooling will pay off
  • Explain what hot runners and conformal cooling are and why they are used
  • Describe advances in simulation of hot runners and conformal cooling in Simulation Moldflow Insight 2013
