Once the mold is prepared and the pattern (the model of the final product) is placed in it, an opening is created to allow the molten iron to flow in. When the iron solidifies, the mold is broken apart to extract the cast piece. This method is cost-effective and can produce complex shapes with good dimensional accuracy.

(1) The influence of casting structure: a. Casting wall thickness, large shrinkage rate, thin casting wall, small shrinkage rate. b. The free shrinkage rate is large, and the hindered shrinkage rate is small.
