Die Casting: The Right Casting Method to Manufacture Aluminum Office Chair Bases
Die casting is the right casting method for creating aluminum office chair bases. Before understanding die casting process of aluminum office chair bases, you should know what is die casting? Die casting is one of the primary casting methods that mainly used to customize complex shapes with light metals such as aluminum alloy, zinc alloy, etc. So, for office chair bases in aluminum alloy, die casting is the way to go.
Basic die casting process of aluminum office chair bases include:
1. Preparing the Mold
As die casting is an OEM service, so before starting the casting process, mold preparation is the first step. Once the mold is made, CFS aluminum foundry applies a lubricant to the interior walls of the mold, which will make the removal of cast aluminum office chair bases easier.
After installing the mold onto the die casting machine, molten aluminum alloy is injected into the mold under high pressure. Make sure the mold is completely closed and sealed in this step. The pressure controlled in die casting process maintains until the molten aluminum alloy is fully cooled and solidified.
3. Cavity Ejection
When the molten material is solidfied, the solid aluminum chair base is formed. Our worker will eject the newly made chair base from the mold. It is worty to mention that, the chair base must be solid for it to eject. If the aluminum material is still liquid, aluminum foundry must wait for it to cool before the chair base is ejected from the mold.
