The article discusses how using SolidWorks software and CAE-driven design can improve the stamping process in plastic machinery manufacturing. By creating a unified design and simulation model, the system ensures that product design, process design, and forming simulation are updated simultaneously. This approach avoids surface and accuracy loss caused by data exchange between traditional CAE software and CAD platforms. The researchers applied this method to simulate the forming of an automobile bumper and found that the system is practical and accurate, as verified by comparing simulation results with experimental results.
