Casting defect Wikipedia

A casting defect is an undesired irregularity in a metal casting process. Some defects can be tolerated while others can be repaired, otherwise they must be eliminated. They are broken down into five main categories: gas porosity, shrinkage defects, mould material defects, pouring metal defects, and metallurgical defects.

5 Steps to Identify Green Sand Metalcasting Defects

Step 1 Identify the Defect. Foundry personnel have a tendency to identify a defect based on cause like slag defect or sand inclusions.
