Magnesium is the lightest structural material supplying very excellent damping characteristics, weldability and superb shielding against electro-magnetic interferance, and is unlimited in supply. It has been an outstanding 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 computers, automotive gear housings, vehicle wheels and engine blocks. The most prevalent techniques to create magnesium parts are die casting and thixomolding processes. Even so, these runner and gating processes provide a low material yield of only 30% for thin-wall casting and can only produce thin walls of among .7mm to 1.2mm. precision investment casting process If we can type magnesium parts from sheet metal just like metal stamping of steel and aluminum parts, we can achieve much better material yield of about 80% and possibly safer operation due to the lower processing temperature. Nonetheless, magnesium is identified to be non-formable as it is really 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 become operative. Substantial process study in this area have resulted in a couple of warm forming hydraulic presses accessible in the marketplace for draw forming. Recently, research in warm draw forming of magnesium to make cell telephone chassis has successfully 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. While the existing warm forming press systems are complex to operate as they demand the preliminary constructing of stroke and force profiles for the precise merchandise making use of data acquisition modules and forming simulation softwares, the increased replacement of aluminum and plastics with magnesium for handheld electronic devices may properly accelerate this procedure. Progressive early adopters of this technologies would have a first mover advantage in the competitive global manufacturing business.
