A differentiation between casting process
TypeMetling LiquidQualityAdvantageDisadvantage
Sand casting (green sand mold)Iron, copper and aluminum etc.LowSave costMore defects
Gravity CastingAluminum alloy etc.HighThe mold can be reused, good surface roughness and accurate dimension.Easy to have pore and shrinkage defects
Investment casting(Lost wax casting)Wide range of applicable metalsHigh1. Reduce costHigh cost
2. Whether it is simple or complex in shape, it can be produced easily casted holes.
3. Reduce processing and wear and tear.
4. Widely material selections and mass production.
5. Precision tolerance: Lost wax casting parts can get tightly dimension without any machining
6. The surface of the casting is fine and the internal structure is dense.
7. Flexiable design.
Die castingLight AlloyHighCastings with accurate dimension depend on the material.Easy to have pores
LOST FOAM (Polystyrene)Wide range of applicable metalsMediumHigh precision without sand core in the traditional casting.Easy to get deformed
Resin shell moldWide range of applicable metalsHighSmall surface roughness, high dimensional accuracy and good qualityHigh cost
