Gravity casting refers to the process of injecting molten metal into a mold under the action of the gravity of the earth, also known as gravity casting. In the broad sense, gravity casting includes sand casting, metal casting, investment casting, lost foam casting, mud casting, etc. The narrow meaning of gravity casting mainly refers to metal casting.

 

Advantages of gravity casting

 

  1.       There are many methods for making metal materials into required products, such as casting, forging, extrusion, rolling, drawing, stamping, cutting, powder metallurgy, and so on. Among them, casting is a basic and commonly used process.

2.      The molten metal is poured into a hollow mold made of a high-temperature resistant material, and the product of the desired shape is obtained after condensation. This is casting. The resulting product is a casting.

3.      Casting can be divided into ferrous metal casting (including cast iron, cast steel) and non-ferrous metal casting (including aluminum alloy, copper alloy, zinc alloy, magnesium alloy, etc.) according to the material of the casting. The precision casting factory specializes in non-ferrous metal casting, with an emphasis on aluminum alloy and zinc alloy casting.

 4. Casting can be divided into sand casting and metal casting according to the material of the casting mold. The precision casting factory is comfortable with both of these casting processes, and designs and manufactures these two types of casting molds by itself.

5. Casting can also be divided into gravity casting and pressure casting according to the pouring process of molten metal. Gravity casting refers to the process of injecting molten metal into the mold under the action of the gravity of the earth, also known as casting. In the broad sense, gravity casting includes sand casting, metal casting, investment casting, lost foam casting, mud casting, etc .; narrow gravity casting refers specifically to metal casting. Pressure casting refers to a process in which a metal liquid is injected into a mold under the action of other external forces (excluding gravity).

In the broad sense, die casting includes die casting and vacuum casting, low pressure casting, centrifugal casting, etc .; the narrow sense of die casting refers to the metal die casting of the die casting machine, referred to as die casting. The precision casting factory has long been engaged in gravity casting of sand and metal molds. These several casting processes are commonly used in non-ferrous metal casting at present, and they are also relatively inexpensive.


Aluminum alloy has a low melting point and good casting properties, and is widely used in many fields such as automotive, medical, automation, and industrial robots. In particular, some requirements are high, the internal cavity is complex, the thickness is large, and it is irreplaceable when high strength is required. Sometimes some products that can be produced by the die casting process are also produced by the aluminum alloy gravity casting process because the mold cost of the aluminum alloy gravity casting process is lower. When the product size is large and the production quantity is small, the aluminum alloy gravity casting process can not only get high quality Products and can greatly reduce the mold costs, is a good choice.
