Basic Knowledge of Metal Casting. Metal casting has been widely used in our residential and industrial fields. Casting is the foundation of modern machinery manufacturing industry.. Casting process is to pour the melted metal into the mold, after the solidification by cooling, to get the curtain shape, size and performance of metal castings.
3. The casting are taken out from the moulds when cold and fettled. 4. The fettled castings are inspected and sent for dispatch. 5. The fettlings and rejected castings constitute the foundry returns (generated scrap) and are returned to melting furnace for re-use. b. Quality Control and Standards:
grasp the complete casting process. Then, some of the latest casting technology can be introduced to the students in order to expand their horizons. That is good for their future development in this field. On the other hand, the needs of the enterprises ought to be considered. In the Pearl River Delta, most of the enterprises are export-oriented.
