Step-by-Step Overview of the Process
- Mold Preparation: First, the mold is preheated and coated to ensure smooth metal flow.
- Metal Injection: Then, molten metal is pushed into the mold at a low, controlled pressure.
- Solidification: The metal cools and hardens within the mold.
- Ejection: Once solid, the casting is removed from the mold.
- Finishing: Lastly, the component undergoes trimming, polishing, or heat treatment for final use.
Key Materials Used in Low Pressure Die Casting
Depending on the specific application and required properties, several metals and alloys are used in the Low Pressure Die Casting process. The most common materials include:
