Magnesium Die Casting: Where Lightweight Meets Uncompromised Durability.
Magnesium Die Casting
Magnesium die casting is a manufacturing process that involves injecting molten magnesium into a mold—whose cavity mirrors the negative shape of the desired part—to form components. It shares similarities with other casting methods, where liquid material fills a cavity to replicate the target product’s form.
Magnesium alloys are melted either in the die-casting machine or a separate furnace. The molten material is then either gravity-fed into the mold to solidify or forced into it and held under high pressure via a hydraulic press (pressure die casting). Once the material solidifies and takes the part’s shape, the mold opens, and the component is removed manually or automatically.
