The origins of die casting can be traced back to the early 19th century when it was primarily used for creating movable type for printing. However, it wasn't until the 20th century that die casting began to see widespread application in industrial manufacturing. The introduction of aluminum alloys and advancements in alloy technology significantly influenced the industry. By the mid-20th century, die casting companies were producing high-quality components that revolutionized manufacturing processes.

2. High Dimensional Accuracy The dry sand mixture can be precisely controlled, enabling the production of parts with tight tolerances. This accuracy is crucial in industries where parts must fit together seamlessly, such as in automotive and aerospace applications.
