The recovered valve gunmetal is first spread on a sorting table and checked for iron contamination with an iron piece detector. At the same time, a visual check is performed to check if there are any foreign materials such as stainless steel or plastic.
The valve gunmetal that has been inspected is packed in a flexible container, then finally inspected again with an iron piece detector before delivered to the manufacturer as a metal raw material.
