Shrinkage porosity results from the casting metal shrinking as it solidifies, leaving small pores. To combat porosity, parts are designed with uniform wall thickness and metal savers to reduce material weight and promote consistent solidification.

DFM can incorporate fillets and radii to eliminate sharp corners, improving material flow and reducing stress concentrations. This design approach minimizes cracking, extends tool life.

Engineers optimize ejector pin bosses by strategically placing, and slightly indenting, them to ensure smooth ejection in the casting. This approach prevents casting defects and enhances overall part quality.

DFM addresses draft by incorporating tapered edges into the design, ensuring parts can be easily removed from the tool without sticking. This enhances mold release and prevents defects.
