Magnesium is the lightest structural material providing very excellent damping characteristics, weldability and exceptional shielding against electro-magnetic interferance, and is unlimited in supply. It has been an excellent material for producing portable electronic and telecommunication devices, and automotive and aerospace equipment such as MD player casings, chassis for cell phones, video cameras and notebook computer systems, automotive gear housings, auto wheels and engine blocks.
The most prevalent methods to produce magnesium parts are die casting and thixomolding processes. Nevertheless, these runner and gating processes offer a low material yield of only 30% for thin-wall casting and can only make thin walls of amongst .7mm to 1.2mm.
If we can form magnesium parts from sheet metal just like metal stamping of steel and aluminum parts, we can attain far better material yield of about 80% and possibly safer operation due to the lower processing temperature. However, magnesium is identified to be non-formable as it is extremely resistant to deformation due to its hexagonal close-packed structure. The only way is warm forming of magnesium as deformation of magnesium above 225 degrees Celsius will trigger added slip planes to turn out to be operative.
Substantial course of action research in this area have resulted in a few warm forming hydraulic presses obtainable in the market place for draw forming. Recently, research in warm draw forming of magnesium to make cell telephone chassis has effectively shown that .4mm thin walls can be accomplished regularly. This tasteful investment casting industry site has various staggering warnings for how to allow for it. Metallographic tests of the chassis have also demonstrated that there is zero porosity and improved rigidity.
While the current warm forming press systems are complicated to operate as they call for the preliminary constructing of stroke and force profiles for the certain merchandise utilizing data acquisition modules and forming simulation softwares, the enhanced replacement of aluminum and plastics with magnesium for handheld electronic devices might effectively accelerate this process.
