Preparation: Ensure the die-casting machine is clean and properly lubricated. This helps in the smooth insertion of the molten zinc alloy into the mold1.
Heating: Heat the zinc alloy to its melting point, which is typically around 387-390°C. The machine’s shot chamber will be hot to facilitate the melting process1.
Injection: Once the zinc alloy is molten, it is injected into the mold cavity under high pressure. The high pressure ensures that the molten zinc fills the entire mold cavity1.
Cooling: Allow the molten zinc to cool and solidify within the mold. This step is crucial to ensure that the part takes the desired shape1.
Ejection: After the part has solidified, unclamp the mold halves and carefully remove the cast part. Be sure to give it enough time to cool completely before ejection to avoid damage1.
Trimming: Remove any excess material, such as flash, sprues, and runners, from the cast part. This can be done using tools like a saw or trim die
