The ThixoForming process offers an opportunity to manufacture high density, complex shaped components from magnesium alloys, for medium to high volume applications. ThixoForming takes advantage of the thixotropic, or semi-solid nature of heated materials, to assist in microstructure refinement and enhanced properties . Injection molding of this semi-solid material yields complex, net shape and high density components. The process offers excellent metallurgical and tolerance capability when compared to conventional die casting. ThixoForming combines the shape making capabilities of plastic injection molding along with conventional die casting technology.
Magnesium alloys are the most common materials utilized.
Once the part solidifies in the mold, it is ejected and trimmed. Because the material is injected under relatively lower temperatures, allowing for laminar material flow, the resulting part has excellent qualities over conventional die casting . Geometries can be more intricate, densities are higher, and the finish is finer in detail. ThixoFormed components range in size from 50 grams to over 4 kilograms. Mold construction consists of either single or multiple cavities depending upon the estimated annual requirements and plan view area of the component.
