Casting machines are devices that manufacture parts of a desired shape by pouring molten metal into a predetermined mold (such as a die or sand mold) and then cooling and solidifying it. Because they can integrally form parts with complex shapes, they are indispensable for producing core components in a wide range of fields, including automobile engine blocks and transmission cases, industrial machinery parts, and architectural hardware. Typical equipment includes die casting machines, which inject molten metal into a die under high pressure, making them suitable for high-precision and mass production. Other types include sand casting machines, low-pressure casting machines, and continuous casting machines. The optimal method is selected based on the material (such as iron, aluminum, or copper alloys), required quality, and production volume. This enables the manufacturing of diverse metal products while achieving both high productivity and quality.
