Sand Casting is very traditional process, In ancient China, there have many products already used this process to produce goods; they can use kind of material(like gold, iron,Brass, Aluminium and so on) to produce various products, till now it still use on many industry area. like many Machine equipment base, what is advantages and disadvantages of sand casting? today let us dig it out.
| Advantages of Sand casting | Disadvantages of Sand casting |
|---|---|
| Simple production process | Handmade process |
| Low cost Casting molds | Low strength |
| Lower production costs | Low dimensional accuracy |
| Wider material choice | Rough surface quality |
| High complexity shapes | More casting defects |
| Short lead time | Unstable casting quality |
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.
