In life and work of people came into contact with a lot of equipment parts are by casting to and product's users are only interested in the quality of clearance of qualified products, and products quality a large part is casting of the decision process, thus casting knowledge is very important.
The following is a description of a casting called: gravity casting, that is, the gravity of the liquid metal under the action of a process. It contains the type is also different, mainly to see you is from which point of view, such as the generalized angle, sand casting, metal mold casting, investment casting, lost foam casting, mud casting, etc. These are a kind of gravity casting; in essence, mainly is to pass the metal mold casting of a production method.
There is a casting process is relatively familiar, that is the pressure casting. In my opinion, it is similar to the gravity casting, but in essence, it is completely contrary to the process of pressure casting, which is the process of casting the casting under the action of external force other than gravity. It also has broad sense and narrow sense in kind, such as including die-casting machine pressure casting and vacuum casting, low pressure die casting, centrifugal casting, etc. These are the generalized pressure casting; however, metal pressure casting is basically a narrow pressure casting, which have similar place and gravity casting.
Although this process is not very complex, but this kind of casting method is still used up to now, you can conclude that they have an unusual place.
