Thixomolding is a semi-solid (Thixotropic) molding process for magnesium somewhat analogous to plastic injection molding.
Magnesium chips are fed at ambient temperature into a heated barrel
and propelled forward by a rotating screw.
The combined heat from resistance type heater bands and the shearing
force provided by the rotating screw create a slurry of spheroidal
solid particles within a molten matrix.
This slurry is forced into a pre-heated mold to produce high precision,
ultra-thin wall net or near net shaped parts.
The process combines the benefits of die casting and plastic injection molding.
