Die casting is a metal casting process in which molten metal is injected into a mold cavity under high pressure. Which of the following is commonly produced by this process?

• A. Die casting
• B. Welding
• C. Forging
• D. Casting

Answer: (A)

Die casting is used to produce metal parts with complex shapes, tight tolerances, and smooth surfaces in high volumes. The result of this process is die castings—the metal components created directly by injecting molten metal into a steel mold under high pressure. The other terms refer to different manufacturing methods or outcomes: welding is joining pieces together, forging reshapes metal by deformation, and casting is a broader category that includes methods other than high‑pressure die injection. So the item commonly produced by this process is the die casting itself.
