In response to increasing sustainability demands, YIZUMI is taking a forward-thinking approach by offering magnesium thixomolding—a resource-efficient alternative to traditional die casting. This process is distinguished by improved energy efficiency and significantly reduced CO₂ emissions.
YIZUMI’s integration of digital twin technology and methodical process optimization represents a milestone in manufacturing technology. By combining low emissions, optimized resource utilization, and cutting-edge digital tools, YIZUMI enables foundries to produce highly precise components while minimizing environmental impact. Companies adopting thixomolding not only benefit from superior quality but also contribute significantly to global sustainability efforts.
How Thixomolding Works
Thixomolding differs significantly from traditional casting methods. The magnesium alloy is processed in a semi-solid state, where it exhibits thixotropic properties. This allows for precise shaping with substantially reduced shrinkage. The alloy (e.g., AZ91D) is injected at temperatures below its liquidus point, eliminating the need for protective gases and significantly reducing CO₂ emissions.
During the process, mechanical shearing in the dosing and casting phases transforms dendritic particles in the melt into a globular structure. This structural change enhances material flow and results in components of the highest quality.
Optimizing Processes with Digital Twins
In collaboration with MAGMA GmbH and their simulation software MAGMASOFT®, YIZUMI employs digital twins to virtually replicate the entire thixomolding process. Key parameters such as injection speed, mold temperature, and cooling systems are simulated, enabling adjustments to be tested before physical trials are conducted.
On a YIZUMI UN1250MGII machine, simulations were combined with real-world casting trials to precisely analyze the effects of various parameters on casting quality. This approach minimizes waste and significantly enhances product quality.
