What is fettling losses?

Fettling losses refer to the material waste and inefficiencies that occur during the fettling process in manufacturing, particularly in foundries. Fettling involves the removal of excess material, such as flash or burrs, from castings to achieve the desired shape and finish. Losses can arise from the removal of excess metal, the use of tools and consumables, and the time spent on manual labor. Minimizing fettling losses is crucial for improving production efficiency and reducing costs.
