Metal casting is a modern process with ancient roots. In the metal casting process, metal parts a produced by pouring molten metal into a mold cavity, either made from a die or sand. In the mold it then cools and hardens in the shape of the mold and later extracted from the mold. Metal casting is arguably the earliest and most influential industrial process in history. It’s used to make many of the metal objects used in our daily lives: automotive parts, train wheels, lamp posts and much more. Die casting is better suited for larger quantities of parts while sand casting is usually for smaller production runs.
