4. Ejection Once the metal has solidified, the die is opened, and the finished casting is ejected from the mold. Any excess metal, known as flash, is trimmed off.

Quality control is paramount in the production of precision cast products. Manufacturers employ advanced inspection techniques such as X-ray analysis and computer tomography to assess component integrity and detect any imperfections. These measures ensure that the end products meet the high standards required in critical applications.

After the mold is created, it is carefully removed from the pattern, creating a cavity in the shape of the intended part. The next step is to pour molten stainless steel into the mold. Stainless steel is chosen for its unique properties, which become significant during the casting process. Its high melting point, typically around 1400 to 1450 degrees Celsius (2550 to 2640 degrees Fahrenheit), requires careful temperature control to ensure an efficient pouring process.
