The type of furnace used depends on the metal being cast and can range from electric induction furnaces to gas-fired furnaces. The metal is heated to its melting point to ensure it becomes molten and ready for pouring. 6. Metal pouring: Once the metal has melted, it is poured into the mold cavity. Care must be taken to ensure the metal is poured evenly and at the correct temperature to prevent defects or inconsistencies in the final casting. 7. Cooling and solidification: After the metal is poured, it begins to cool and solidify inside the mold cavity. The cooling time depends on the size and thickness of the casting, as well as the type of metal used. Cooling can be accelerated by using cooling fans or water-cooled molds. 8. Mold removal: Once the metal has completely solidified, the mold is removed. This can be done by shaking, vibrating, or breaking the mold, depending on its type. The mold is typically destroyed during this process, as it cannot be reused. 9. Finishing and cleaning: The final step involves removing any excess material, such as gates and risers, from the casting.
