What Is Zinc Die Casting?
Fundición a presión de zinc es un especializado metal casting process that uses high pressure to force molten zinc alloy into a steel mold (morir), producing complex, piezas de alta precisión. As a core tecnología de fundición, it leverages zinc’s unique properties—excellent castability, fortaleza, and affordability—to meet diverse industry needs.
un claro descripción general del proceso revela su eficiencia: Molten zinc (heated to 380–420°C, far lower than aluminum) undergoes high-pressure injection into a closed die. The metal cools and solidifies rapidly, then the die opens to eject the finished part. Mesa 1 compares zinc die casting to other die casting process types:
| Tipo de fundición a presión | Metal Used | Melting Point | Beneficio clave | Caso de uso ideal |
| Zinc Die Casting | Zinc Alloys | 380–420°C | Bajo costo, small part precision, fast cycle time | Carcasas para electrónica, hardware, automotive small parts |
| Aluminum Die Casting | Aleaciones de aluminio | 650–750°C | Ligero + alta resistencia | Automotive structural parts, componentes aeroespaciales |

The Zinc Die Casting Process
El Zinc Die Casting Process follows a streamlined workflow optimized for speed and precision, leveraging zinc’s low melting point to minimize cycle times.
- Injection Process: Molten zinc alloy is drawn into a heated gooseneck (in hot chamber machines) and injected into the die cavity at high pressure (30–100 MPa) y velocidad (1–5 m/s), ensuring full filling of even tiny details.
- Cooling Process: The metal solidifies rapidly (5–15 seconds) in the die, maintaining dimensional tolerances while pressure is held to reduce porosity.
- Ejection Process: El dado se abre, and ejector pins push the finished part out—zinc’s low shrinkage rate ensures the part retains its shape.
- Trimming Process: exceso de material (destello) is removed via automated trimming tools, creating a clean, finished part.
- Quality Control Process: Parts undergo inspection for defects, precisión dimensional, and surface finish before moving to surface treatment or shipping.
De término medio, the total cycle time for a small zinc part (p.ej., an electronics connector) is just 10–20 seconds—faster than most other die casting processes.
