Examination of the design principles of machines used for pressure die casting of magnesium alloys

Magnesium is the lightest of all metals used as the basis for constructional alloys. It is this property which entices automobile manufacturers to replace denser materials, not only steels, cast irons and copper base alloys but even aluminium alloys by magnesium based alloys.The simplest division of the process for a cold chamber is the following: 1) filling the shot sleeve, 2) slow plunger velocity, 3) filling the runner system 4) filling the cavity and overflows, and 5) solidification process (also referred as intensification process). During all cycle of enjection process, the most important two parametres; pressure and velocity. Because of this, these two parameters is used as key parameters by most of systems, due to control of process.Die casting compenents of magnesium alloys has been increased by the years. And as can be seen the use of magnesium is predicted to rise into the new century.In this study, examination of the design principles of machines used for pressure die casting of magnesium alloys which has 1 MN (100 ton) locking force.Key words: Magnesium Alloys, Pressure Die Casting, Design Principles
