>> The chassis is built out of an injection molded Magnesium...
Would someone more qualified than I comment on this? I seem to remember from high school that magnesium is highly flammable. Its autoignition temperature is fairly high at 473C/883F, but I could see a li-ion battery malfunction leading to a pretty nasty fire hazard.
Is there some special process that can be applied to magnesium to ensure that this product doesn't turn into a flare?
- pyre 14y agoI would venture a guess that it's not pure Magnesium, but an alloy of some sort.
- minikomi 14y agoOne process is described on wikipedia, using inert gas to prevent ignition[1]: For magnesium alloys, thixomolding uses a machine similar to injection molding. In a single step process, room temperature magnesium alloy chips are fed into the back end of a heated barrel through a volumetric feeder. The barrel is maintained under an argon atmosphere to prevent oxidation of the magnesium chips. A screw feeder located inside the barrel feeds the magnesium chips forward as they are heated into the semi-solid temperature range. The screw rotation provides the necessary shearing force to generate the globular structure needed for semi-solid casting. Once enough slurry has accumulated, the screw moves forward to inject the slurry into a steel die.
