Before the first drop of molten metal ever enters a die, mold flow simulation gives engineers a powerful preview of what’s going to happen inside the tool. By digitally simulating how metal fills the cavity, mold flow analysis helps predict problems—before they become expensive tooling mistakes.
What is Mold Flow Simulation?
Mold flow simulation is a computer-aided engineering (CAE) process used to visualize the flow of molten metal through the sprue, runner, gates, and into the mold cavity. It models temperature gradients, pressure, fill time, and air entrapment—key variables that affect casting quality.

Why It Matters
Detecting Air Entrapment and Porosity
Simulations highlight where trapped gases may form, allowing engineers to redesign venting or runner paths.
Avoiding Cold Shuts or Incomplete Fill
By analyzing fill patterns, engineers can adjust gate sizes and injection profiles to eliminate areas that cool too quickly.
Minimizing Shrinkage and Warpage
The software can predict uneven cooling, helping to adjust mold cooling channels or casting wall thickness to reduce distortion.
Reducing Tool Trial Iterations
With upfront insights, simulations reduce the need for multiple tooling trials—saving both time and money.
At LVIO Precision, we collaborate with experienced toolmakers who incorporate mold flow simulation into the design phase of every critical project. This ensures a smoother DFM process, shorter time-to-market, and higher first-shot success rates for your die-cast components.
