Casting Defect\u00a0in Lost Form Casting Causes of Wrinkle Casting Defect Wrinkle casting defects arise when polystyrene foam undergoes pyrolysis due to exposure to high-temperature molten metal. This process generates a significant amount of carbon, which accumulates on the cavity&#8217;s outer surface. These defects frequently occur at the colder ends of the liquid metal flow or where the flow is interrupted, such as at the top of grinding balls. Methods to Address Wrinkle Casting Defect Using Low-Density EPS Foam Selecting low-density EPS foam specifically designed for casting can help mitigate wrinkle defects. This material gasifies quickly and leaves minimal residues, reducing the likelihood of wrinkle formation.
