Sand Casting

Yes!I am interested
The main sand casting material has iron (grey Iron, ductile Iron, S.G. Iron), bronze, brass, aluminum, zinc, steel, stainless steel, etc. Material selection is according to technical standards, including ASTM, ANSI, SAE, DIN and BS.

1. The cast parts can vary greatly in size and weight, ranging from a couple ounces to several tons.
2. The small sand cast parts include gears, pulleys, crankshafts, connecting rods and propellers. The larger sand cast used for large equipment housings or heavy machine bases.
3. Sand casting machine is also common in producing automobile parts, such as engine blocks, engine manifolds, cylinder heads and transmission cases.
4. Because of the used sand casting modeling material is cheap and easy to get, the mold has the advantages of simple manufacture, the casting of single production, mass production can be used, for a long time has been casting production is the basic process.

Sand Casting Machine Processes
Process Advantage
Green sand casting 1. Featuring low cost, flexibility, high productivity, short production cycle.
2. With approximately 60 to 70% usage of all sand casting.
3. Green sand casting is cheaper than resin bonded sand casting.
Resin bonded sand casting 1. It can effectively prevent the sand sticking on the cast parts.
2. It can removed nitrogen, sulfur and other gases.
3. It can guarantee the quality and stability of cast parts.
Shell mold casting 1. It offers better surface finish, better dimensional tolerances and higher throughput due to reduced cycle times.
2. The materials covers cast iron, grey iron, ductile iron, carbon steel, stainless steel, alloy steel, aluminum, aluminum alloy etc.
Lost foam casting 1. Lost foam casting offers similar benefits of lost wax casting, but avoiding complex process of making wax shell.
2. It is relatively simple to make mold and allows recycling of sand.
