These include very rough or uneven surfaces “veins” or “rat tails” caused by cracking of the mold at high temperatures “elephant skin,” which is puckered due to quick cooling burned sand and stripping defects. Surface casting defects are visible to an inspector. Some casting defects like a very rough surface are visible to the unassisted eye. The different types of defects include surface defects, inclusion defects, molding and pouring defects, and cooling defects. Defects in casting represent unwanted abnormality in the metal casting manufacturing process. Like other manufacturing processes, casting is vulnerable to several types of defects, whether it’s sand casting or lost-wax casting. These inspection methods help identify potential casting defects. ![]() Testing methods are in place to help inspect castings for quality assurance. Metal casting in foundries is a complex process. Dive deep into surface, inclusion, molding, pouring, and cooling defects Metal casting is vulnerable to defects, so it is vital to test and identify them with proper inspection.
