  • Sand inclusion - Giesserei Lexikon

    Sand can also be torn off when stripping the pattern and during the casting process itself and thus cause such defects. The defect manifests itself often as thickening zones on surfaces and edges of a casting, mostly near the gate, and accordingly as sand crusts in remote casting sections. Sand inclusions are one of the most common casting defects.
