What is Solving Pin Hole Challenges in Foundry about?
The document discusses a foundry that was experiencing an increase in pin holes in their castings starting in April 2008, which were investigated and found to likely be caused by carbon monoxide bubbles due to impurities in a purchased carbon raiser additive; after testing samples and material changes, purchasing a different carbon raiser solved the pin hole problem, though the document notes that new challenges will continually arise for metallurgists to address.
