Use a casting-stage inspection gate to catch incomplete areas, obvious surface problems, distortion, poor fit and sprue-related issues before more labour is added.
Casting inspection exists to stop defects before additional finishing, setting and assembly work increase the cost of correction. Compare the physical cast component with the intended model or job specification and look for obvious issues that affect later operations.
A visual inspection cannot reveal every internal casting defect. Where a product or process requires specialist testing, use the appropriate technical method.
