Metalcasting is a modern manufacturing industry, and cast products are utilized in 90% of durable goods, from lamp posts to space shuttles. Still, no casting is perfect. Even with recent innovations in simulation and process technology, nearly every cast product will contain some level of defect. A clear understanding of casting defects is vital for any casting customer, as it helps guide realistic expectations when working with a casting facility.

While experienced casting facilities are skilled in finding a balance between cost and quality, purchasers should be closely involved in determining admissible levels of defects in deliverable products.
