Some of the Casting Simulation Results

  • Flow Velocity

    Flow Velocity

    In casting simulations, flow velocity is crucial for predicting how molten metal fills the mold. It helps identify issues like air entrapment, turbulence, and cold shuts, ensuring smooth flow, better mold filling, and improved casting quality.

  • Sample Image 2

    Flow Temperature

    In casting simulations, flow temperature is vital to ensure proper mold filling and solidification. It helps detect risks like cold shuts, misruns, and uneven cooling, enabling optimized gating design and improved casting integrity, surface finish, and mechanical properties.

  • Sample Image 3

    Air Enrapment

    In casting simulations, air entrapment indicates where air may get trapped during metal flow. Monitoring it helps prevent porosity, blowholes, and incomplete filling. Identifying air pockets early allows for better venting and gating design, improving overall casting quality and reliability.

  • Sample Image 4

    Flow Velocity Vector

    In casting simulations, flow velocity vector direction shows the path and behavior of molten metal within the mold. It helps identify turbulence, short-circuiting, and uneven filling, guiding gating system optimization to ensure smooth, uniform flow and high-quality castings.

  • Sample Image 5

    Fill Time Plot

    In casting simulations, the fill time plot shows how long molten metal takes to fill the mold cavity. It helps identify slow-fill zones, cold shuts, and misruns, enabling optimization of gating design for balanced filling, better quality, and defect prevention.

  • Sample Image 1

    Flow Oxides

    In casting simulations, the flow oxides plot highlights areas where oxides may form due to turbulent metal flow. This helps detect risks of inclusions, weak spots, and surface defects, allowing engineers to refine gating and pouring to minimize oxidation-related issues.

  • Sample Image 2

    Maximum Air Pressure

    In casting simulations, the maximum air pressure regions plot identifies areas where trapped air builds up during mold filling. High air pressure can lead to blowholes, porosity, or incomplete filling. This plot guides venting and gating improvements to enhance casting quality.

  • Sample Image 3

    Materail Trace Lines

    In casting simulations, the material trace lines plot tracks the path of molten metal during filling. It helps visualize flow patterns, detect dead zones, and analyze mixing behavior, enabling better gating design and ensuring complete, uniform filling for high-quality castings.

  • Sample Image 4

    Solidification

    In casting simulations, solidification analysis reveals how and where molten metal solidifies in the mold. It helps identify shrinkage defects, hot spots, and non-uniform cooling, allowing optimization of riser design and cooling rates to improve casting quality and integrity.

  • Sample Image 5

    Shrinkage Porosity

    Shrinkage porosity indicates areas where metal volume loss during solidification can create voids. Identifying these zones helps optimize riser placement, cooling rates, and solidification patterns, ensuring sound castings with improved structural integrity and reduced internal defects.
