... porosity in as-cast parts. It begins by describing a typical cycle for a traditional cold-chamber die casting machine, using detailed illustrations to show how gas can become trapped in the liquid metal. It then presents various remedies, ultimately focusing on vacuum die casting for the production of high...

... alloys can also be die cast. Parts produced by the die casting process are shown in Fig. 1 . The primary categories of the conventional die casting process are the hot chamber process and the cold chamber process. These main process variations have been enhanced in recent years to produce high-integrity...

... Two basic types of die casting machines are used for production: the hot chamber and the cold chamber. The hot chamber machine consists of an injection mechanism that is immersed in molten metal in a furnace attached to the machine. These machines are quick in operation and are normally used for lower...
