Optimizing a Foundry Process
Through Advanced Simulation
Explore how an automotive foundry leveraged PoligonSoft to eliminate misruns, optimize cooling line speeds, and significantly enhance production yield and cycle times.
The Automotive Foundry Challenge
This section outlines the primary business and engineering challenges faced by modern automotive foundries. The goal is to provide context on why advanced simulation is critical for maintaining competitiveness in high-volume manufacturing.
In the highly competitive automotive sector, foundries are under constant pressure to optimize both cycle time and yield. Complex geometries, such as engine blocks and transmission housings, are prone to defects during the solidification process.
Key Obstacles
- → High Scrap Rates: Unpredictable defects like misruns and porosity leading to costly rework.
- → Long Design Cycles: Traditional trial-and-error physical prototyping is prohibitively slow.
- → Thermal Inefficiencies: Suboptimal cooling line layouts increasing overall cycle times.

Interactive Simulation: Cooling Line Optimization
This interactive section demonstrates the power of simulating complex thermodynamic parameters. Adjust the cooling line speed using the slider below to observe the simulated trade-off between production cycle time and casting yield (defect-free parts).
* At low speeds, cycle time is high, but thermal gradients are stable.
Resolving Misruns in Test Castings
This section highlights a specific, documented instance where simulation directly identified the root cause of a critical casting defect. By dynamically altering variables in the virtual environment, engineers found the exact threshold required for success.
Citing PoligonSoft, we note a use case: simulation identified a misrun defect and showed that raising the pouring temperature would fix it.
Source: poligoncast.in ↗A misrun occurs when liquid metal freezes before completely filling the mold cavity. Interact with the temperature controls to see how thermal adjustments impact the simulation model.
Broader Impact & Proven Results
This section demonstrates that the benefits of simulation extend far beyond single part optimization. Entire production processes benefit from the predictive capabilities of tools like PoligonSoft.
Elimination of misruns and macro-shrinkage prior to physical casting.
Shortened time-to-market by removing physical trial-and-error iterations.
Optimized gating layouts maximizing the ratio of good parts per pour.
Transforming the Foundry Ecosystem
The integration of advanced solver technologies profoundly impacts the macro-economics of the foundry floor. By simulating the holistic process—from mold filling and solidification to final heat treatment—facilities can ensure that gating layout changes do not inadvertently introduce new thermal stresses.
As highlighted in the PoligonSoft use cases, whether addressing misruns via pouring temperature or comparing water versus oil quenching during heat treatment simulation, the overarching outcome is a dramatic shift from reactive troubleshooting to proactive engineering.
