What Is Aluminum Die Casting?
Pressofusione di alluminio is a specialized metal casting process that uses high pressure to force molten alluminio (O aluminum alloys) into a steel mold (die), creating complex, dimensionally accurate parts. As a core casting technology, it leverages the unique properties of aluminum—lightweight, forza, and recyclability—to meet diverse industry needs.
A clear process overview reveals its efficiency: Molten aluminum (heated to 650–750°C) undergoes metal injection into a closed die at pressures ranging from 50–150 MPa. The metal cools and solidifies quickly, then the die opens to eject the finished part. Table 1 compares aluminum die casting to other die casting process tipi:
| Die Casting Type | Metal Used | Key Benefit | Ideal Use Case |
| Aluminum Die Casting | Aluminum Alloys | Lightweight + high strength | Automotive structural parts, aerospace components |
| Zinc Die Casting | Zinc Alloys | Basso costo, small part precision | Electronics housings, hardware |
| Magnesium Die Casting | Magnesium Alloys | Ultra-light, high thermal conductivity | Laptop frames, drone parts |

The Aluminum Die Casting Process
IL die casting process for aluminum follows a structured workflow optimized for efficiency and precision, with each step tailored to maximize part quality.
- Mold Preparation: The steel die is preheated (150–250°C) and coated with lubricant to prevent metal sticking and ensure smooth ejection.
- Metal Injection: Molten lega di alluminio is injected into the die cavity at high speed (2–8 m/s) and pressure (50–150 MPa), ensuring full filling of complex geometries.
- Cooling & Solidification: The metal cools rapidly (10–30 seconds) in the die, maintaining dimensional accuracy while pressure is held to reduce porosity.
- Ejection: The die opens, and ejector pins push the finished part out. Excess material (flash) is removed via trimming.
- Post-elaborazione: Parts undergo quality inspection (dimensional checks, surface testing) and optional secondary operations (lavorazione, trattamento superficiale).
On average, the total cycle time for a medium-sized aluminum part (per esempio., an automotive sensor housing) ranges from 20–40 seconds.
