Magnesium is the lightest structural material supplying really excellent damping characteristics, weldability and outstanding shielding against electro-magnetic interferance, and is unlimited in supply. It has been an outstanding material for creating portable electronic and telecommunication devices, and automotive and aerospace gear such as MD player casings, chassis for cell phones, video cameras and notebook computers, automotive gear housings, auto wheels and engine blocks. The most frequent approaches to generate magnesium parts are die casting and thixomolding processes. However, these runner and gating processes supply a low material yield of only 30% for thin-wall casting and can only generate thin walls of in between .7mm to 1.2mm. rent investment casting foundries If we can form magnesium parts from sheet metal just like metal stamping of steel and aluminum parts, we can obtain much better material yield of about 80% and possibly safer operation due to the lower processing temperature. Even so, magnesium is recognized to be non-formable as it is quite 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 cause further slip planes to become operative. Substantial process research in this location have resulted in a few warm forming hydraulic presses readily available in the marketplace 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. Metallographic tests of the chassis have also demonstrated that there is zero porosity and elevated rigidity. Even though the present warm forming press systems are complex to operate as they require the preliminary creating of stroke and force profiles for the specific items making use of information acquisition modules and forming simulation softwares, the enhanced replacement of aluminum and plastics with magnesium for handheld electronic devices may effectively accelerate this procedure. Progressive early adopters of this technology would have a first mover advantage in the competitive worldwide manufacturing market.
