What are the microstructural defects in cast iron? Causes and solutions

In green sand cast iron, microstructure deviation is a defect that can directly affect the mechanical properties, hardness, and machinability of the product. This error occurs when the metal microstructure of the casting does not meet the requirements for morphology, size, quantity, or distribution. ...

Casting chipping defect in sand casting: Causes, impacts, and remedial measures

In the process of cast iron casting using sand molding technology, in addition to defects formed during metal solidification such as gas porosity, shrinkage, or mold shift, castings can also encounter defects arising after casting. One of the common defects is **casting chipping defect**.This defect ...

Sand burn-on defect in sand casting: Causes, effects, and solutions

In the process of cast iron production using green sand casting technology, the surface quality of the casting is one of the important criteria for evaluating product quality. Besides defects such as gas porosity, mold shift, or burrs, sand burn is a fairly common surface defect, especially for larg ...
