What Is Magnesium Die Casting?
Fundición a presión de magnesio es un especializado metal casting process that uses high pressure to force molten magnesio into a steel mold (morir), producing ultra-light, piezas de alta precisión. As an innovative fundición a presión método, it capitalizes on magnesium’s unique properties—low density, excellent strength-to-weight ratio, and good castability—to meet the demands of weight-sensitive industries.
un claro descripción general del proceso highlights its efficiency: Molten magnesium (heated to 650–675°C) is injected into a closed die at high pressure (40–120MPa). The metal cools and solidifies rapidly, then the die opens to eject the finished part. Mesa 1 compares magnesium die casting to other common die casting metals:

The Magnesium Die Casting Process
El die casting process for magnesium follows a structured workflow optimized for speed and precision, leveraging magnesium’s unique thermal properties.
- Preparación: The steel die is preheated (180–250°C) and coated with a lubricant to prevent metal sticking and ensure smooth ejection.
- Inyección: Molten aleación de magnesio is injected into the die cavity at high speed (2–6 m/s) y presión (40–120MPa), ensuring full filling of complex geometries.
- Enfriamiento: The metal solidifies rapidly (10–25 seconds) in the die, maintaining precisión dimensional while pressure is held to reduce porosity.
- Expulsión: El dado se abre, and ejector pins push the finished part out—magnesium’s low shrinkage rate (0.8–1.2%) ensures the part retains its shape.
- Postprocesamiento: exceso de material (destello) is trimmed, and parts undergo optional machining or surface treatment to meet final specs.
- Automatización: Brazos robóticos manejan la inyección., expulsión, y pasos de posprocesamiento, reducing human error and increasing production efficiency by 30%.
De término medio, the total cycle time for a medium-sized magnesium part (p.ej., a laptop frame) ranges from 15–30 seconds.
