Casting process of alloy gravity casting and advantages of small batch production
- May 21, 2018 -

Alloy gravity casting has lower melting point and better casting performance when used, and can be widely used in motors, telecommunications, hardware tools, automobiles, motorcycles, and other fields during use. Aluminum alloys have lower melting points and better casting properties, especially for large-walled products.

To a certain extent, alloy gravity casting mainly refers to the process in which metal liquid is injected into the mold under the action of gravity. It is also called gravity casting to a certain extent. To a certain extent, its broad-based gravity casting effectively includes metal. Casting, investment casting, sand casting, lost foam casting, mud casting, etc.

Alloy gravitational casting can be effectively divided into gravity casting and pressure casting according to the casting process of its molten metal. During the operation, gravity casting mainly refers to the process in which the molten metal is injected into the casting mold under the action of the earth's gravity. It is also called casting. Gravity casting in a broad sense includes sand casting, metal casting, investment casting, lost foam casting, and mud casting.

Alloy gravity casting of metal mold casting mainly uses the heat-resistant alloy steel to make the casting hollow mold during the operation. The metal mold can be gravity-casted or pressure-casted. Metal-type molds can be used many times and repeatedly, and once casting metal liquid, one casting is obtained, which has a long life and high production efficiency.

Alloy gravity cast metal-type castings not only have good dimensional accuracy and smooth surface when used, but also have a casting strength higher than that of a sand mold and less likely to be damaged when the same molten metal is poured. Therefore, in the mass production of small and medium-sized non-ferrous metal castings, as long as the melting point of the casting material is not too high, it is generally preferred to use metal casting.

Alloy gravity casting For low-volume production, the cost of molds allocated to each product is obviously too high, and it is generally not easy to accept. Because metal-type molds are limited by the size of mold materials and the capacity of cavity processing equipment and casting equipment, they are also incapable of handling particularly large castings.
