What Is Copper Die Casting?
Fundición a presión de cobre es un especializado metal forming process that uses high pressure to force molten copper alloy into a steel mold (morir), producing parts with exceptional conductivity, fortaleza, y durabilidad. As a key branch of die casting basics, it addresses the unique challenges of copper’s high melting point (1,085°C) by using specialized equipment and techniques.
un claro descripción general del proceso highlights its efficiency: Molten copper alloy (heated to 1,100–1,200°C) is injected into a preheated die at pressures ranging from 80–150 MPa. The metal cools and solidifies under pressure to minimize porosity, then the die opens to eject the finished part. Mesa 1 compares copper die casting to other common die casting metals:

The Copper Die Casting Process
El Copper Die Casting Process follows a structured workflow optimized for copper’s high melting point and thermal properties.
- Preparación del troquel: The steel die (made from heat-resistant H13 or H11 steel) is preheated to 250–350°C and coated with a high-temperature lubricant to prevent metal sticking.
- Inyección de metales: Molten copper alloy is transferred from a holding furnace to the die’s cold chamber, then injected into the cavity at high speed (1–4 m/s) y presión (80–150MPa) to ensure full filling.
- Cooling and Solidification: The metal solidifies under pressure (15–40 segundos, dependiendo del tamaño de la pieza) to reduce porosity and maintain precisión dimensional. Los canales de refrigerante en el troquel aceleran este proceso y evitan la deformación.
- Expulsión: El dado se abre, and ejector pins push the finished part out—copper’s moderate shrinkage rate (1.2–1.5%) ensures the part retains its shape.
- Trimming and Finishing: exceso de material (destello) is removed via automated trimming tools, and parts undergo optional machining or surface treatment.
- Control de procesos: Los sensores en tiempo real monitorean la temperatura, presión, and injection speed to ensure consistency and minimize defects.
De término medio, the total cycle time for a medium-sized copper part (p.ej., an electrical connector) ranges from 25–45 seconds.
