Formation and prevention of shrinkage cavities and porosity in lost foam casting of ductile iron parts
Shrinkage cavities and porosity are common defects in lost foam casting of ductile iron parts, which are mainly caused by volume shrinkage and insufficient shrinkage compensation during solidification. The following is a detailed analysis of its formation mechanism and prevention and control measures: 1. Causes of shrinkage cavities and porosity 1.1 Solidification characteristics of ductile […]
