Methodology for a good practice to investigate casting defects

”Look at it, Think about it, Try it & Control it”
By Pierre-Marie CABANNE & Serge GRENIER, RIO TINTO Iron & Titanium – Sorelmetal

Depending on the domain of activity and the process of the foundry (automotive sector, heavy and large castings, safety parts or street castings, thin or thick wall, hand molding or automatic molding line, …), the total level of scrap observed (including customer scrap) usually varies between 1 to 5%. Achieving less than 1% is a great challenge and proves that the plant is mature and has its process under control, as well as a very good maintenance activity. It is also indicative of a good sense of anticipation and a high level of knowhow; something which can only be achieved by continuously investing in both equipment and personnel training.
