Using fast, simple, and accurate metal extrusion simulation tools, advanced numerical algorithms are used through visualization to predict visible or invisible extrusion defects during the use of virtual molds in the extrusion process environment, and to determine the causes and failure areas of defects, including profile deformation, profile surface quality, mold strength, work strip design, and prediction of the welding surface of hollow profiles Skin tracking analysis (tail end defects), grain structure prediction, pressure distribution, strain distribution, temperature management, etc. Xingshun has established a dedicated research group for simulation and mold testing technology. Members of each group work together according to three-dimensional drawing, model establishment, simulation operation, report analysis, etc. After the simulation is completed, they can selectively print comprehensive reports or enter various classification interfaces such as stress and flow rate to check and analyze the results, which serves as an important reference for establishing mold design plans.
