Advantages of Sand casting


Simple production process


Use common Sand make mould or Pattern out. and ouring into Melten metal liquid into mould or pattern. after cool down, take the part out.


Low cost Casting molds


the Mould or pattern most is square one. it is simple with low cost.


Lower production costs


this process is good for low volume with very thick wall parts. and part price will not expensive.


Wider material choice


there have many material can choice, like iron, steel, Aluminium, Brass and so on, only the sand foundry have this material.


Short lead time


From make mould or pattern out to Product been casting out, it will take short lead time.


Disadvantages of Sand casting


Handmade process


Manpower to Monitor and controll this whole casting process.  will cause unstable quality.


Low strength


Sand casting is pouring molten material into by hand. no pressure. cause the part inside is loose. and easy to have porosity defects. it is different with Gravity Die Casting and High Pressure Die Casting.


Low dimensional accuracy & Rough surface quality


due to this process is use Sand core to make parts out, cause the casting parts surface is rough, also dimension is not precision, some of the dimension have to use CNC to Machine.
