There are many ways to classify casting processes. These classification methods are divided based on some detailed differences in general processes.

Let's first introduce the general process.

According to the shape of the casting, we first make a mold, which is convenient for us to pour liquid metal into it. A funnel can be set up on the mold to facilitate subsequent processes. Depending on the material of the mold, we can divide casting into sand casting, metal mold casting, ceramic mold casting, etc.

There are many ways to make molds, which leads to many casting classification methods. Kindly contact us, If you want to know more.

Melting the metal, we also need to add some auxiliary materials during the melting process to increase the final performance of the casting. Methods for melting metal include electromagnetic heating and flame heating.

Pour the metal down the funnel into the mold. During the pouring process, we need to pay attention to the temperature of the metal, surface oxide scale, etc. to avoid defects in the casting.

Overall cooling. Wait for the mold and interior to cool. This process can divide casting into gravity casting and die casting.

For casting cleaning, we open the mold, clean the mold surface, and cut off the excess parts of the casting.

Surface treatment, we use grinding equipment to treat the surface of the casting to make the surface smoother. It can then be left in place longer by applying a rust-proof coating. There are many methods of surface treatment, but due to space reasons, I will not explain them in detail here. Those who are interested can use the search function to fully understand.
