Aluminum gravity casting is more advanced than sand casting

Green sand casting must be the most acient casting process. However speaking to aluminum green sand casting, it is not so acient as we thought. Because even the invitation of manufacturing means of aluminm alloy happened hundred year ago. No to mention the more complicated aluminum casting process. Anyway, aluminum green sand casting process is actually much aged than other aluminum casting process. However, aluminum gravity casting process has also got a long industrial history. Compared with aluminum green sand casting, aluminum gravity die casting can achieve much thinner wall thickness and much higher dimensional precision level. Another empressive advantage is gravity casting process can speed up manufacturing cycle that is to increase yeild capacity dramatically.

The other reason why aluminum gravity casting process is overwhelming preferred to greed sand casting is that gravity casting process can be assisted by automatic machine rather than plain and simple manual job. As we all know, aluminum green sand casting is featured as its dirty and heavy working environment. In the ancient time, even the sand casting workers were looked downup by people having a little bit more decent job. It is also refused and digused by young generation. But although aluminum gravity casting process is not so good as other manufacturing job like sheet fabricating or machining, its working environment is improved a lot compared with green sand casting process.

Better mechanical property of aluminum gravity cast parts than that of sand casting

Aluminum gravity casting process can not only achieve much thinner wall thickness and higher dimension precision, but also the mechanical property of casting itself. Aluminum gravity casting process applies metal die to commodate melted alloy and get it solidfied inside. Compared with sand sheel, the metal die can disspas the heat more quickly, as the melted alloy get solidifed more quickly. According the metallurgy knowage, the metal part get solidifed in shorter time can achieve much finner crystallic structure. The finner inner crystallic structure means much better mechanical property such as much higher hardness and strenghtness.NEED NUMRERICAL DATA SAMPLES HERE
