Die casting is a metal casting process that involves feeding molten nonferrous alloys into dies under high pressure and at high speed to rapidly create molded products. The main materials used in die casting are alloys of aluminum, magnesium and zinc.
Die Casting Step as bellow:
Preparing the Mold
The first step of high-pressure die casting is mold preparation. During this initial step, the manufacturing company applies a lubricant to the interior walls of the mold. This is important because the lubricant regulates the mold’s temperature while also creating a film between the molten metal and the mold, thereby allowing for easier removal of the casting.
Injection
After preparing the die mold, the manufacturing company injects it with molten metal. The mold must be completed closed and sealed during this step. Otherwise, it won’t be able to “accept” the highly pressurized molten metal. Depending on the specific application, the molten metal may be injected into the mold at a pressure of between 1,500 to 25,000 pounds per square inch (PSI). The mold maintains this pressure until the molten metal has cooled and solidified.
Cavity Ejection
Next, the manufacturing company ejects the newly made cavity from the mold. The mold itself typically features ejector pins that, when engaged, release the cavity. Of course, the cavity must be solid for it to eject. If the raw metal is still liquid, the manufacturing company must wait for it to cool before it can eject the cavity from the mold.
Shakeout
The fourth and final step of high-pressure die casting is shakeout. During this step, the manufacturing company separates any scrap metal from the newly created cavity. It’s not uncommon for high-pressure die casting to produce excess scrap metal. In other words, not all of the molten metal is used to create the casting. Some remains stuck inside the mold. As a result, the scrap metal must be removed before the mold can be reused.
To recap, high-pressure die casting generally consists of four steps: preparing the mold, injecting the mold with molten metal, ejecting the newly created cavity from the mold, and separating scrap metal from the cavity.
