Process Parameters
| Process | Pressure die castings | Gravity casting | Sand casting |
| Forming method | The molten metal is press-fitted into the mold with a die-casting machine and is rapidly cooled under high pressure. | The molten metal is injected into the metal mold under the action of earth gravity, and the expected shape of the product is obtained after cooling. | The molten metal is poured into the sand mold made with clay bonded sand to obtain casting after cooling. |
| Molding material | Metal mold；repeated use； highest production efficiency； mass production. | Metal mold；repeated use； high production efficiency； mass production | Sand mold used once, low production efficiency, small batch production |
| Pattern | Heat-resistant alloy steel with high cost | Heat-resistant alloy steel with high cost | Wooden or Al-alloy pattern with low cost |
| Part weight | few grams to30kg | 1KG – 1000KGS | 20-1000kg |
| Wall thickness | 0.3—10mm thin wall | More than die castings | Thick wall |
| Surface quality | Dimension accuracy CT6-8Surface roughnessRa6.3-Ra12.5；Small machining allowance | Dimension accuracy CT CT7-10Surface roughnessRa12.5-Ra25，Commonly machining allowance | Dimension accuracy CT10-12Surface roughnessRa25-Ra50；Big machining allowance |
| Inner quality | Easy to appear internal air holes; Can ‘t carry out T6 heat treatment. | No sand holes and air holes; internals with uniformly and compact; T6 heat treatment to obtain high mechanical strength. | Easy to appear shrinkage and porosity and internal air hole al air hole; Low the internal density; T6 heat treatment to obtain high mechanical strength. |
| Application | Widely used in automobiles, tractors, electrical instruments, medical devices and other fields; such as transmission case，gear cover，housing，cover etc. | Widely used in automobile, motorcycle, motor, communication, hardware tool and other fields; such as bracket, Crankcase，intake manifold etc. | Widely used in aviation, automobile, power meters, tools and civil utensils and other fields; such as pump body, impeller, gearbox, instrument shell etc. |
