What is the casting (high-pressure die casting, gravity casting, low-pressure casting) on the use of CAE simulation simulation analysis

In die casting, low-pressure casting and gravity casting (including sand/metal type), CAE simulation is used as the core digital tool for coupled numerical simulation of the whole casting process by constructing a three-dimensional model covering the mold, casting and sprue system. Its common core analysis module includes:Charging process simulation(Analyze liquid metal flow patterns, predict cold segregation and gas wrapping),Solidification process simulation(analyzing temperature field and solidification sequence, predicting shrinkage) andStress/deformation simulation(Prediction of thermal stresses, residual stresses and deformations). For process characterizationDie casting CAE focuses on high-speed mold filling and air roll analysis, mold heat balance and cooling optimization.；Low-pressure casting CAE focuses on precise control of air pressure field, sequential solidification and shrinkage simulation.；Gravity casting CAE focusing on natural flow regime under gravity, solidification paths and riser make-up efficiency assessmentThe fundamental role is to scientifically predict defects and optimize process parameters and mold design. The fundamental role is to scientifically predict defects, optimize process parameters and mold design to significantly improve casting quality, shorten development cycles and reduce trial and error costs.

Aluminum casting filling flow simulation analysis is a key means of high-precision numerical simulation of the flow state of aluminum liquid during the filling process in the casting system using Computational Fluid Dynamics (CFD) technology. By establishing a complete three-dimensional model including gate, runner and cavity, the analysis dynamically simulates the free surface flow of liquid aluminum, air-rolling phenomenon, turbulence development and temperature change, and accurately reveals the formation mechanism and location of defects such as fluid separation, cold segregation, air wrapping and oxidized slag which may occur in the filling process, so as to provide a scientific visual basis for optimizing the layout of the pouring system, controlling the filling speed and improving the internal quality of the castings. and decision-making support.

Aluminum casting gas simulation analysis is the use of multiphase flow computational fluid dynamics (CFD) technology, specifically to track and analyze the casting mold filling process of air or cavity gas by the liquid aluminum involved in the formation of porosity defects and stagnation of the fine simulation process. It is through the construction of “liquid aluminum - gas” two-phase or “liquid aluminum - gas - oxide” multiphase model, accurate simulation of liquid aluminum turbulence front of the splash, convergence, vortex and other complex flow patterns, dynamically capture the gas involved in the fragmentation, polymerization and uplift and escape behavior, so as to Accurately predict the size, location and distribution probability of the gas holes inside the casting. This analysis is a key digital tool for optimizing casting system design (e.g., avoiding turbulence), setting reasonable venting schemes and process parameters to minimize harmful gas entrainment, and improving casting metallurgical quality and service performance.

Shrinkage simulationCAE simulation of aluminum casting shrinkage simulation

Aluminum casting shrinkage simulation analysis is a key simulation technology based on the principles of heat transfer and solidification shrinkage to predict the void defects formed in the casting during solidification due to liquid shrinkage and solidification shrinkage without sufficient liquid metal shrinkage. The analysis is performed by constructing an accurate 3D model of the casting-gate system, coupling the temperature field, solid-phase rate field and liquid flow field, and dynamically tracking the solidification sequence and the formation of isolated liquid-phase zones, so as to accurately predict the dimensions, morphology, and spatial distribution of volumetric defects such as shrinkage holes and shrinkage loosening. The core purpose is to scientifically evaluate and optimize the riser position and size, cold iron arrangement and pouring process parameters to achieve active control of the solidification path and shrinkage channel, and ultimately obtain a dense and sound internal organization of the casting.
