Default Re: Any Reason?

Patterns (molds are made from patterns and are destroyed when the casting is released) can certainly suffer damage that can end up being cast into the pans made from them, but what's normally seen in Wapaks are defects in the casting process, like sags and sand shifts. Such things are normally the result of improper (or lazy) packing of the sand around the pattern, resulting in the mold not remaining stable when the pattern is removed and the mold halves reassembled, or when the molten iron entered the mold. These kinds of defects are seen in other makers' pans, though not to the degree and severity seen in Wapaks. Perhaps it's an indication their quality control standards were somewhat lax compared with the competition's.
