“…The updated dendrite-to-globule transformation mechanism also provided ideas for designing the simplified processing systems through eliminating the injection screw completely and replacing it with a plunger. The recent design by MAXImolding represents a vertically oriented, semisolid metal alloy injection molding machine with a plunger instead of the injection screw [19]. The design assumes that the generation of thixotropic slurry with spherical solid particles in the melt can be achieved in the thermal mass reactor under the sole influence of heat.…”

Injection molding has proven for over 150 years to be the efficient mass manufacturing technology of net-shape components from plastics, however, its application to metallic alloys, despite four decades of commercialization, still creates challenges. Although early designs assumed a direct replacement of plastic with magnesium, subsequent research revealed essential differences in machinery and processing requirements, imposed by metallic alloys. The key discovery revealed that the dendrite-to-globule transformation during coarse particulate melting is caused by strain induced melt activation (SIMA) due to feedstock deformation imposed at their manufacturing stage, not due to the injection screw shearing during processing. As a result, the process control parameters and the screw and barrel design can be optimized with a focus on other screw functions. That discovery also led to the simplified machinery designs, eliminating the complex injection screw, and replacing it with a simple plunger.
