gravity casting的意思|示意

Gravity casting, also known as permanent mold casting, is a metal casting process that is characterised by the use of a permanent mold to shape molten metal into the desired part. This method is called as gravitational casting due to the force that is exerted by the molten metal as it is poured into the mold.

Gravity casting is a relatively simple process that begins with the creation of a mold. Molds may be created using a variety of materials, including sand, plastics, and wax. Once the mold is completed, the molten metal is poured into the cavity of the mold and allowed to cool and solidify.

Gravity casting is a versatile process that can be used to produce parts of all sizes, shapes, and design complexities. Moreover, the process can be used with a variety of alloys, including aluminum, brass, copper, steel, and magnesium.

The advantages of gravity casting include low costs, shorter lead times, as well as the ability to achieve high levels of detail and precision. The process also produces parts with consistent internal and external dimensions, making gravity casting an ideal choice for industries such as aerospace, automotive, and medical.

There are several disadvantages to this type of casting, including the presence of seams and other surface imperfections. Additionally, gravity casting is a relatively slow process, and more intricate molds may require subsequent manual machining to achieve the desired level of detail.

Overall, gravity casting is a suitable choice for metal casting projects that require high levels of precision and detail. The process is relatively inexpensive and offers shorter lead times than other casting processes, making it an ideal choice for low-volume production runs.
