Die casting

What is die-casting? 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 Die-casting flow chat: Die casting parts surface treatment: 1.Painting 2.Powder coating 3.Plating 4.Oxide anodizing 5.Polishing, sanding 6.Oil painting 7.Bead blasting 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.
