Pressure casting is called die casting
Die-casting method in which a molten alloy liquid is poured into a pressure chamber,
a cavity of a steel mold is filled at a high speed, and the alloy liquid is solidified under pressure to form a casting.

· Advantage and disadvantage of die casting
Advantage :good quality high production efficiency good price
Disadvantage: material limited :only aluminum zinc magnesium lead copper tin can be used to casting so far.
Expensive equipment, and high cost tooling

· The major flaw of die casting
Inside: Stomata, shrinkage hole, sand hole, loose
Surface: Crack, cold partition, wrong type, oversized billet, bubble, carbon deposit,
sticking mold, strain, sag, trace, pockmark, scouring, crack, top drum, piercing
Die-casting is one of the most advanced metal forming methods. With the continuous improvement of die-casting technology,
die-casting alloys are no longer limited to non-ferrous metals such as zinc, aluminum, magnesium and copper. The size and weight of die-
casting parts will also increase as the power of the die-casting machine increases, so the prospect of die-casting is very broad.
Die casting process has its Superiority also has its limitations. The quality, quality and cost of the products
processed by different processes are different. How to choose the right product processing
process in the production process requires us to choose.
