What Is Copper Die Casting?
Copper Die Casting es un especializado metal forming proceso que usa alta presión para forzar fundido copper alloy en un molde de acero (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 destaca su eficiencia: 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, Entonces el dado se abre para expulsar la parte terminada. 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: 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 metal: Fundido 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 (80–150 MPA) to ensure full filling.
- Cooling and Solidification: The metal solidifies under pressure (15–40 segundos, Dependiendo del tamaño de la parte) to reduce porosity and maintain precisión dimensional. Los canales de refrigerante en el dado aceleran este proceso mientras evitan la deformación.
- Expulsión: El troquel se abre, and ejector pins push the finished part out—copper’s moderate shrinkage rate (1.2–1.5%) Asegura que la parte conserve su forma.
- Trimming and Finishing: Exceso de material (destello) se elimina a través de herramientas de recorte automatizadas, 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.
