Gravity cast aluminum specification

In our life, we come into contact with many parts of equipment and work by casting. Only qualified products will be favored by users, and a large part of the product quality is determined by the casting process, so we must be familiar with the casting process.


We will discuss one of them: gravity casting aluminum gas is actually the process of injecting molten metal into the mold under the action of gravity. It includes different kinds, mainly depending on which aspect you look at, for example, sand casting, metal casting, investment casting, lost foam casting, mud casting, etc. in the broad sense are gravity casting; in the narrow sense, gravity casting mainly refers to metal casting.


At present, there is a less used casting process, that is, low-pressure casting. It looks like gravity casting, but the opposite is true. The liquid metal of low pressure casting is injected into the mold under the condition of complete vacuum and no external force. It can also be divided into broad sense and narrow sense, for example, the broad sense of pressure casting includes pressure casting of die casting machine, vacuum casting, low-pressure casting, centrifugal casting, etc.; the narrow sense of pressure casting specifically refers to metal mold pressure casting, similar to gravity casting aluminum gas. Although it is not a very complex processing technology, these casting methods are still the most used at present. As you can see, they certainly have their own attraction.
