Why are gravity casting machines widely used?

2025,01,07

The Gravity Casting Machine uses the principle of earth's gravity to make the metal flow to every corner of the gravity casting mold. Gravity casting machines are often used to produce aluminum castings, so they are also called aluminum alloy gravity Casting Machine. Zhuhua Technology's tilted gravity casting machine is also used by manufacturers to produce aluminum castings because it can accelerate the flow of molten metal and speed up the shaping of cast products by tilting the frame.

　Gravity casting machines are widely used in various industries. This is related to the fact that the density of aluminum castings is smaller than that of cast iron and cast steel, but its strength is higher. The use of aluminum castings under the same load can reduce the structural weight, so gravity casting machines are widely used in the aviation industry, power machinery and transportation machinery manufacturing. The properties of aluminum also result in aluminum alloys having better surface gloss and corrosion resistance.

　　Gravity casting machines are mainly used to produce AC2A aluminum alloy materials, followed by alloy materials. However, after casting, certain post-heat treatment procedures are required to improve the mechanical properties of the casting, such as tensile strength and hardness. However, alloys with different compositions have different performance requirements for castings, so the processing methods for castings are also different.

　　Gravity casting machines can also be used to produce ZA27 high-aluminum-zinc-based alloys with an aluminum content of approximately 27%. This material is also suitable for gravity casting to produce casting products. It has good strength and toughness, low specific gravity and wide application range.

　　Due to the good thermal conductivity of aluminum, aluminum castings produced by gravity casting machines are also used in heat exchange devices used in chemical production and power machinery parts that require good thermal conductivity, such as cylinder heads and pistons. The characteristics and properties of cast aluminum make it widely used, and the mechanical properties imparted to cast aluminum by gravity casting machines make it even more widely used.
