In industrial production, gravity die casting is a widely used metal forming technology. With its unique technological advantages, it plays an important role in manufacturing high-precision and high-quality metal products. This paper will introduce the gravity die casting technology in detail, including its principle, characteristics, application fields and future development trend.

Principle of 1. Gravity Die Casting Technology

Gravity die-casting technology, as the name suggests, is a process method that uses gravity to naturally fill and solidify molten metal in a mold. In the die-casting process, the molten metal is first heated to a certain temperature to maintain its fluidity and wettability, and then injected into the pre-designed mold cavity through the gate. Under the action of gravity, the metal surface gradually rises until it fills the entire cavity. Subsequently, the mold is cooled, the metal solidifies and shrinks, and finally the desired metal product is obtained by demolding.

Features of 2. Gravity Die Casting Technology

1. High precision: gravity die-casting technology uses precision molds for molding, which can ensure the dimensional accuracy and surface quality of products.

2. High quality: Because the metal fills the mold cavity naturally under the action of gravity, the generation of gas and inclusions is avoided, thereby improving the density and mechanical properties of the product.

3. Wide applicability: Gravity die casting technology is suitable for forming a variety of metal materials, such as aluminum alloy, copper alloy, zinc alloy, etc.

Energy saving and environmental protection: Compared with the traditional casting process, gravity die casting technology has low energy consumption and low pollution, which meets the requirements of modern green manufacturing.
