Large thin-walled casting saddle

The saddle is a key component connecting the suspension and frame. Due to the newly developed saddle being a cast product, its large size, complex structure, and thin wall easily lead to problems such as shrinkage porosity and shrinkage defects during the production process. Casting simulation is a technology...
