Die Casting Process is a metal casting process that is characterized by forcing the molten metal into a mold cavity under the application of high pressure or under gravity. Because of the metal mold, the same mold can be used for producing the infinite number of castings, hence the process is also called a Permanent Mold Casting Process.
In permanent mold casting, also referred to as gravity die casting, molten metal is poured by gravity into a reusable permanent mold made of two or more parts (Figure 6.10).This process is closely related to die casting; however, the tolerances and surface finishes achievable by this process are not as good as those obtainable by “pressure” die casting.

The basic die casting process involves pushing molten metal into a metal mold called a “die.” Die casting is one of the most used methods for producing high-quality parts for a variety of applications.
injection of molten metal into the die cavity. Proper die design and venting of the air in the die and also optimized process parameters have a very critical precaution to reduce the gas porosity. Today, there are various venting systems used for facilitating the evacuation of air from mold. The use of vent systems in the die casting processes

Gas porosity is the biggest single problem in die casting. High gas content prevents heat treating or welding and makes strength unpredictable. There are three major sources of gas porosity for die castings: Trapped air, Steam, Gas from lubricant. Gas porosity is round and generally smooth, although it can be flattened to some extent by pressure.
