Low pressure casting has a number of significant advantages that make it outstanding in a variety of applications. The following are the main advantages of low pressure casting parts:
1. High casting quality: In the process of low pressure casting, the molten metal is filled and solidified under pressure, making the casting dense tissue and good air tightness. At the same time, due to the smooth filling process, the billowing, impact and splashing of the metal liquid are avoided, and the quality of the casting is further improved.
2. High dimensional accuracy of the casting: the metal liquid fills the cavity quickly under the action of pressure, which can accurately copy the mold surface. By controlling the casting temperature and the cooling rate of the liquid metal, the dimensional accuracy and shape of the casting can be precisely controlled.
3. Wide range of application: low pressure casting is suitable for a variety of casting materials, such as sand, lost wax, shell, graphite, semi-metal and metal. At the same time, low pressure casting is also suitable for a variety of casting alloys, including non-ferrous alloys, cast iron and cast steel.
4. Convenient production operation: the pouring system of low pressure casting is simple, which can reduce or eliminate the riser, and the metal liquid that has not yet solidified can flow back to the crucible, reducing the loss of the metal liquid. In addition, low pressure casting is easy to achieve mechanization and automation, improving production efficiency.
5. Casting surface clean: due to the metal liquid filling under pressure, can improve the flow of metal liquid, conducive to the formation of a clear outline, smooth surface of the casting.
6. High mechanical properties: the casting crystallizes and solidifies under pressure, can be fully supplemented, the casting has dense structure, good mechanical properties, such as tensile strength and hardness, etc., have been improved.
In summary, low pressure casting parts have the advantages of high quality, high precision, wide applicability, easy operation, high mechanical properties and surface smoothness, which make it widely used in aviation, aerospace, automotive, machinery manufacturing and other fields.
