• Shrinkage: Caused by metal solidifying and contracting, can be prevented by using risers to feed molten metal during solidification
• Cold shuts: Occur when molten metal fails to fuse properly, can be prevented by ensuring adequate pouring temperature and mold preparation
• Cracks: Caused by internal stresses or external forces, can be prevented by using proper casting design and cooling methods

8. How do you ensure the quality of molten metal before pouring it into molds?

To ensure the quality of molten metal before pouring:

• Test the metal composition using spectroscopy or other analytical methods
• Inspect the metal visually for any impurities or defects
• Maintain proper temperature and slag control
• Use fluxing agents to remove impurities
