Pressure Die Casting Process:
Pressure die casting is a metal casting process where molten metal is forced under high pressure into a sealed metal mold cavity, where it solidifies, and then the casting is ejected.
Molten metal, typically aluminum or zinc alloys, is prepared in a furnace. The molten metal is then forced under high pressure into a tightly closed metal die cavity. The metal is held in place by the pressure until it solidifies. Once solidified, the die is opened, and the casting is ejected. Depending on the application, the casting may require further finishing processes.
Key Features of Pressure Die Casting:
1. High Speed and Pressure:
Molten metal is injected rapidly and under high pressure, often exceeding 1000 bar.
2. Rapid Cooling:
The process allows for rapid cooling and solidification, leading to high-precision castings.
3. Complex Shapes:
Pressure die casting can produce complex shapes with intricate details.
4. High-Volume Production:
It is a high-volume manufacturing process suitable for producing large quantities of parts.
5. Common Materials:
Commonly used materials include aluminum, zinc, magnesium, and copper alloys.
