Simulation-Based Design of Large Steel Castings

Large steel castings — from turbine housings to structural frames — present unique engineering challenges. Their massive geometry, prolonged cooling cycles, and complex thermal behavior increase the likelihood of defects, making simulation essential for achieving quality, reliability, and production efficiency.

Why Simulation Matters

Advanced casting simulation helps engineers predict thermal behavior, eliminate defect-prone regions, and optimize process parameters before production begins — reducing risk in large, high-value steel castings.

Simulation transforms the design process by predicting failure before metal is ever poured. PoligonCast uses industry-leading tools to model every critical phase, enabling engineers to identify risks early, optimize designs, and improve casting quality before production begins.

Mold Filling

Predict turbulence, air entrapment, and cold shuts during pour.

Solidification

Map thermal gradients to identify hot spots and shrinkage zones.

Stress Analysis

Evaluate residual stress and distortion before tooling is built.

Predict Before You Produce

By simulating mold filling, solidification behavior, and residual stresses digitally, foundries can eliminate costly trial-and-error processes and move into production with greater confidence.

From Concept to Production

PoligonCast's iterative simulation workflow eliminates costly physical trials. Each design cycle refines gating systems, riser placement, and cooling channels — converging on an optimized solution before any foundry resources are committed.

Controls fluidity, mold filling behavior, and solidification timing throughout the casting.

Determines thermal properties, shrinkage characteristics, and microstructural evolution.

Heat transfer coefficients and mold materials directly affect cooling rates.

Large section thickness variations influence feeding paths and defect formation.

Why Calibration Matters

Even small deviations in pouring temperature or alloy composition can significantly shift solidification behavior in large castings. Accurate parameter calibration ensures simulation predictions remain aligned with real-world foundry performance, minimizing risk and maximizing casting quality.

Simulation Delivers ROI

Advanced casting simulation transforms foundry performance by reducing defects, minimizing costly physical trials, and lowering material waste — delivering measurable improvements in quality, efficiency, and profitability.
