Green Sand Castings

Green sand casting process has been widely used worldwide, and many types of metal castings were produced by this process.

Green sand materials are very cheap and recyclable. They could be used to produce small and middle sizes and weights castings. In addition, this material is also suitable for both small amount and large batch production. However, it is only suitable for making iron castings, not for steel castings.

The followings are some green sand castings produced by our foundry.

1. Valve Bodies



Butterfly valve bodies normally have many models, but small annual demand. So, they are suitable for green sand. Both GGG40 and GGG50 ductile irons are suitable material grades for these products. Our foundry are producing valve bodies from DN50 to DN500.

2. Tractor Parts



Tractor and auto parts have large annual demand, and have high requirements to the dimensional tolerance and material quality. Therefore, we produced these parts by automatic molding line. We are produced tractors parts for John Deere and some auto parts manufacturer in China.

3. Brackets for trucks



Ductile iron brackets are very important casting parts for engineering trucks, especially for hydraulic system. High percent of spheroidization and less iron casting defects are the key aspects of product quality. We are producing many cradle brackets for our clients in Italy, Germany and UK.

4. Stove grates



Stove grates and burners do not have high requirements to the material grade. Normally, GG15 and GG20 are very suitable. However, the surface smoothness and less sand holes are very important. Green sand could meet the middle requirements, and shell molding could meet the high requirements, but which is more costly.

5. Boiler ash doors



Boiler parts normally required to add some content of Cr to resist high temperature. Of course, surface quality is also important for ash doors. However, most of boiler parts do not have large annual demand, so green sand castings are suitable for these products.
