Low Pressure Permanent Mold Casting of Magnesium-Recent Developments 880509

A system for low pressure permanent mold casting of magnesium alloys is presented. The equipment exploits new concepts of transfer of molten metal, eliminating the risks for melt contamination.
Consistent quality is secured by extensive recording of process parameters and the use of a flexible computer system to operate and monitor the system.
Properties of a successful permanent mold casting alloy is discussed in general. These principles are applied in the selection of suitable magnesium alloys.
An example of application of the present low pressure die casting technology is provided by wheel castings for the automotive industry.
